[0001] The present invention relates to knitted gloves for protecting the hands of the wearer
against physical hazards, such as abrasion, cuts or puncturing, The invention, further,
relates to methods of making such knitted gloves.
[0002] Personal protective gloves are used in many areas of activity, for instance, industry,
agriculture and leisure activities. Gloves typically have four finger stalls to cover
each of the four fingers and a thumb stall to cover the thumb, but may also be mittens
which have a thumb stall and fewer than four finger stalls, usually one to cover all
four fingers together. Gauntlets are gloves, including mittens, which have extended
wrist-covering areas to protect the arms. Gloves, whether typical style, mitten style,
or gauntlet style, all have a thumb stall separate from the stall which encloses the
forefinger to allow the wearer to grip objects. Gloves also have a palm region and
the inside edge of this, i.e. the edge which joins the edge of the forefinger stall
to the base of the thumb stall, is generally known as the thumb crotch area of a glove.
Protective gloves are essential items in hazardous handling environments where an
important property of the glove is resistance to physical harm caused by abrasion,
cutting, or puncturing. Protective gloves must also be comfortable to maximise the
willingness of handlers to wear the gloves during potentially dangerous handling procedures.
[0003] In harsh physical environments, the useful life of a glove depends very much on the
strength of the thumb crotch area since this is subjected to stress due to the constant
flexing of the thumb and forefinger to grab hold of, and grip, objects. Consequently,
it is beneficial to increase the strength of the thumb crotch area so as to increase
the safety of the wearer and to increase the useful working life of the glove.
[0004] Many safety gloves are made up of a primary fabric layer, known as a liner, which
is then covered with a secondary elastomeric polymer, plastic or rubber layer. Such
primary fabric layers are the foundation of a glove acting as both a physical reinforcement
for the outer polymer elastomeric layer and also as a moisture absorbant or sweat
management inner material. Traditional cut and sewn fabric glove liners are being
increasingly replaced by automated knitted glove liners, often referred to as shells.
[0005] Methods of knitting glove liners are well known to those practised in the art. There
are now many manufacturers of flat bed knitting machines for knitting gloves. Probably
the best known is Shima Seiki, of Wakayama City, Japan. Examples of patents relating
to flat bed knitting machines include
US 5,398,527 and
US 5,992,183, both in the name of Shima Seiki Manufacturing Limited.
[0006] It has been long known that gloves will last longer and give greater protection when
the thumb crotch is reinforced. With both traditional cut and sewn fabric liners and
knitted liners, additional pieces of fabric have been sewn into the thumb crotch area.
The same can be said for newer machine knit liners where additional materials are
sewn into the crotch area. Sometimes, liners with polymer dip coatings are subjected
to multiple dipping steps or are multi-layered specifically in the thumb crotch area
to increase protection and durability.
[0007] A simple, previously-known method to increase the strength of the thumb crotch is
with the use of a sewing machine to add a line of lock stitch, commonly known as Overlock
stitching, around the crotch edge, around the thumb crotch palm edge and, optionally,
up the forefinger of cut and sewn liners and machine-knitted liners. This additional
sewing runs along the edge of the forefinger and then down around the thumb crotch
and up the inside edge of the thumb.
[0008] These conventional methods of thumb crotch reinforcement, whether by multiple-layer
polymer dip-coating, by the sewing on of patches in the crotch area, or by adding
Overlock stitching to the liner edge, all require additional processes and so affect
the final production costs, both in terms of materials and manufacturing time.
[0009] Various manufacturers have tried to address the issue of providing additional reinforcement
to the thumb crotch area of a glove. For instance,
US 7,089,600 describes a process which involves the double polymer coating of the forefinger to
thumb crotch region of a glove.
US patents Nos. 6,962,064,
7,213,419,
7,555,921 and
7,908,891 describe the knitting of gloves with variable knitted regions. The provision of a
polymer coating containing a hard particulate filler to a knitted glove liner or shell
by a dip coating method is described in
US 9,456,645.
[0010] There is a range of glove knitting machines. These are set in gauges of machine which
relate to needles per inch. Usually, the machines are rated as 7, 10, 13, 15 and 18
gauge. There are machines which are termed 18 gauge. These, having 18 needles per
inch, will knit finer yarns and produce thinner finer fabrics from finer yarns as
opposed to 7 gauge knitting machines, which, with only 7 needles per inch, knit much
heavier, coarser yarns so producing heavier fabric gloves.
[0011] Generally, the greatest number of safety gloves made today are made on the finer
15 gauge knitted shells. Such 15 gauge shells are then coated with an elastomeric
outer layer. These gloves are, thus, lighter and more dextrous. However, gloves that
are much lighter and dextrous face a problem when higher physical strength is required.
In most cases, lighter gloves fail in the thumb crotch prematurely, long before the
palm or finger regions split or wear through. The reason for the premature thumb crotch
failure is due to the constant grab, grip and holding actions during a work process
on a relatively lighter weight dextrous glove material.
[0012] Knitted gloves, for the purposes described above, are currently made using flat knitting
machines that use a number of needles in the form of a needle array in a needle bed
and a single feed of yarn, or yarns. Typical gloves comprise eight basic component
knitted sections to form the finished glove. These eight components include one component
for each of the four fingers and thumb, two components for the palm including an upper
section and a lower section, and finally one component for the wrist area. All of
these sections are essentially knitted tubular or conical sections that join to each
other fashioning the general anatomical shape of a hand. Conventional knitting processes
use a flat knitting machine to knit each of these areas in a particular sequence.
The sequence of knitting the components follows with one finger at a time, beginning
with the little finger and continuing on through the ring and middle finger to the
forefinger. After each finger is knitted using only selected needles in the needle
knitting bed, the knitting process for each finger is stopped, and yarn is cut and
bound. The finished knitted finger or component is held in place by holders, weighted
down by sinkers. The next finger is then knitted sequentially one at a time using
a different set of needles in the needle bed. When all four fingers are knitted in
this fashion, the knitting machine then knits the upper section of the palm, picking
stitches from each of the previously knit four fingers. After knitting an appropriate
length of the upper palm, the thumb portion is then initiated. Next the lower section
of the palm is knitted using all of the needles across the needle bed. Finally, the
knitting machine knits the wrist component to the desired length. The sequence of
knitting the components of the glove is illustrated in Fig 1. The number of knitted
courses down each of the knitted components is controlled by a computer program in
the knitting machine where the number of courses can be varied to suit the required
lengths of the components. It is well known by those practised in the art as how to
set up the knitting machines to knit the required gloves.
[0013] The typical flat knitting machine has two stationary knitting beds arranged in an
inverted V formation. Latch needles slide in the tricks during the knitting action.
For a needle to be selected for knitting, the butt of the needle is caused to protrude
out of the needle bed. The needles are controlled as they pass through the tracks
formed by angular cams of a bidirectional cam system attached to the underside of
a carriage that transverses the bed in a reciprocating manner across the machine width
on guide rails.
[0014] In the knitting process using the machine described above, needles are selected for
use in knitting using needles which are located in the knitting bed. A drum, which
is cylindrical, and rotatable about its central axis and which has a plurality of
lateral grooves in its outer surface which are parallel to each other and to the axis
of rotation of the cylinder is located beneath the needle bed. The drum has a number
of needle selection pins or rods laid down in the grooves of the drum. The length
of the pin for each portion of the glove to be knitted (fingers, thumb, palms and
wrist) is different and it defines the number of needles to be activated for each
portion. This controls the width of the knitted component. The needle bed comprises
a plurality of needles ready for activation in the knitting process. Each needle is
retained slidably in a needle jack which is itself retained in a control jack. The
control jacks are located above the needle selection drum. The control jack has a
butt which extends into a groove of the needle selection drum. If the groove does
not contain a needle selection pin, the position of the control jack is not altered
and the needle retained is not brought into action in the knitting process. If the
drum rotates to present a groove, to the control jack butt, which does contain a needle
selection pin, the needle selection pin in the groove of the drum pushes up the control
jack in which the needle is secured. The control jack causes the needle butt to protrude
upwards out of the needle bed with the result that, as the carriage moves across the
knitting bed, it contacts the needle butts and so engages those needles in the knitting
process. This is shown diagrammatically in Fig. 2. Fig. 2 shows a cross sectional
view of the needle bed, wherein a needle 1 is secured to needle jack 2 retained in
control jack 3. When the control jack 3 is pushed up by a pin 4 located in a groove
5 of needle selection drum 6 this causes the needle jack butt 7 to be raised. When
a needle moves up the knitting bed, the latch of the needle opens, thus allowing the
needle hook to hold yarn. The needle then moves downward taking the yarn with it.
The yarn is then pressed by sinkers to complete the stitch and, hence, advances the
fabric formation process. This conventional operation of a flat knitting machine creates
a glove with the conventional edges which, as described above, have to be provided
with reinforcement in at least the thumb crotch area by additional processes which
increase production time and costs.
[0015] It is the aim of the present invention to overcome the problems of the prior art
by providing knitted gloves with higher strength in the thumb crotch area which do
not require additional processes to achieve this. It is also the aim of the present
invention to provide methods by which such knitted gloves may be produced on a flat
knitting machine.
[0016] Accordingly, the present invention provides a knitted glove comprising at least one
finger component,
an upper palm component,
a thumb component,
a lower palm component, and
a wrist component
wherein each of the components comprises courses and each course is made of stitches,
wherein each of the courses of the upper palm component includes a tuck knit stitch
adjacent the upper palm inner edge and each of the courses of the thumb component
includes a tuck knit stitch adjacent the thumb inner edge, such that the glove has
a tuck knitted ridge along the upper palm inner edge, around the thumb crotch and
along the thumb inner edge.
[0017] The invention also provides a method of making a knitted glove comprising knitting,
in sequence
at least one finger component,
an upper palm component,
a thumb component,
a lower palm component, and
a wrist component,
wherein each of the components comprises knitted courses and each course is made of
stitches,
wherein each course of the upper palm component is knitted to include a tuck knit
stitch in the course adjacent the upper palm inner edge and each course of the thumb
component is knitted to include a tuck knit stitch in the course adjacent the thumb
inner edge, such that a tuck knit ridge is created along the upper palm inner edge,
around the thumb crotch and along the thumb inner edge as the upper palm component
and the thumb component are knitted sequentially.
[0018] Thus, according to the invention, it is possible to provide a knitted glove which
is provided with a high strength ridge in the thumb crotch region while it is being
knitted on the glove knitting machine.
[0019] The knitted glove of the invention comprises at least one finger component, i.e.
at least one component for enclosing the fingers of the wearer's hand. The four fingers
of the wearer's hand can be enclosed in a single component and a glove providing a
single enclosure for all four fingers of a wearer's hand is generally called a mitten
as mentioned above. The four fingers of a wearer's hand may each be enclosed separately
in a conventional glove which has four separate finger components, In either case,
the index finger of the wearer's hand is enabled to interact with the thumb so as
to allow a holding or gripping action principally involving the thumb and the index
finger of the hand.
[0020] A knitted fabric consists of a number of consecutive rows or courses of intermeshing
of loops of a yarn (stitches). Each of the components of the knitted glove of the
invention comprises a plurality of courses. Thus, the length of a component is determined
by the number of courses across the width of the fabric. This number will be determined
by the size of the garment to be produced,
[0021] In addition to the finger component(s), the lower palm component and the wrist component,
the knitted glove of the invention comprises an upper palm component and a thumb component.
[0022] The upper palm component is the component to which the at least one finger component
is adjoined, The upper palm component has an inner edge which adjoins the thumb crotch
area and the edge of the glove adjacent the index finger position in the finger component
and, also, an outer edge which adjoins the edge of the glove adjacent the little finger
position in the finger component. Thus, the upper palm inner edge is on the thumb
side of the glove. Each of the courses or rows of the upper palm component includes
a tuck knit stitch adjacent the upper palm inner edge. By the term "tuck knit stitch",
we mean a stitch which knits two consecutive courses or rows together. The presence
of a tuck knit stitch in each of the courses or rows of the upper palm component adjacent
the upper palm inner edge results in a ridge that projects outwards along the upper
palm inner edge.
[0023] The thumb component has an inner edge which faces the upper palm inner edge and the
edge of the glove adjacent the index finger position in the finger component and an
outer edge. Each of the courses or rows of the thumb component of the glove includes
a tuck knit stitch adjacent the thumb inner edge. The result of the presence of the
tuck knit stitches adjacent the thumb inner edge is that a tuck knit ridge extends
from the upper palm inner edge, around the thumb crotch and along the thumb inner
edge. This ridge provides increased strength to the glove in the thumb crotch area
which not only improves the wear resistance and, thus, the working life of the glove
but also improves the safety afforded to the wearer by the glove.
[0024] In a preferred embodiment, each of the courses of at least the lower region of the
finger component which encloses the index finger of the wearer also includes a tuck
knit stitch adjacent the edge of the finger component which is closest to the position
of the index finger. Thus, in the case where the glove has one finger component for
enclosing all fingers of the wearer, each of the courses or rows of at least a lower
region of the finger component adjacent the upper palm component includes a tuck knit
stitch adjacent the index finger edge, such that the glove has a tuck knit ridge along
the index finger edge of the finger component. Preferably, the tuck knit ridge extends
continuously down from at least a lower region of the index finger edge, along the
upper palm inner edge, around the thumb crotch and along the thumb inner edge. The
continuous nature of such a ridge gives a glove increased strength and resistance
to wear.
[0025] In the case where a glove has four finger components, each of the courses or rows
of at least a lower region of the index finger component adjacent the upper palm component
preferably also includes a tuck knit stitch adjacent the outer edge of the index finger
component such that the glove has a tuck knit ridge along the outer edge of the index
finger component. According to an embodiment, the glove has a tuck knit ridge that
extends continuously down from at least a lower region of the outer edge of the index
finger component, along the upper palm inner edge, around the thumb crotch and along
the thumb inner edge. The continuous nature of such a ridge gives a glove increased
strength and resistance to wear.
[0026] As stated above, the finger component preferably has a tuck knit ridge along at least
a lower region of the index finger edge. This is a consequence of each of the courses
or rows of at least a lower region of the finger component having a tuck stitch which
stitches together consecutive courses or rows in the fabric. By the term "at least
a lower region", we mean at least one tenth (
1/
10) of the length of the finger component from the bottom of the finger component, preferably
at least one eighth (⅛), more preferably at least one quarter and most preferably
at least one half of the length of the finger component measured from the bottom of
the finger component.
[0027] According to a different preferred embodiment, the glove of the invention having
a tuck knit ridge along upper palm edge, around the thumb crotch and along the thumb
inner edge, whether or not it also has a tuck knit ridge along at least a lower region
of the index finger edge as described above, also has a tuck knit ridge along the
edge of the heel of the hand (i.e. along the outside edge of the palm/hand). Such
a tuck knit ridge, in such an embodiment, extends along at least part of the outer
edge of the glove, lying between the base of the little finger component and the wrist
component.
[0028] The glove of the present invention may be knitted from yarn comprising natural fibres,
synthetic fibres or mixtures thereof. For example, the yarns used to knit the glove
may be spun yarns, textured filament yarns or multicomponent composite yarns. Examples
of compositions that may be used as, or in, yarns include cotton, nylon fibres, polyester
fibres, high performance polyethylene (HPPE) fibres or aramid or other fire-resistant
fibres that can be used to knit gloves.
[0029] Typically, the knitted gloves of the invention will additionally have a coating on
at least part of the glove of an elastomeric polymer composition, for instance a natural
or synthetic rubber composition. Such a coating may be provided on any, or all, of
the fingers, thumb, thumb crotch, upper and/or lower palm in order to provide glove
surfaces that have water or oil-resistance, extra strength or improved gripping or
holding properties.
[0030] The invention further provides a method of making a knitted glove, as stated above.
The method comprises the steps of knitting, in sequence, at least one finger component,
an upper palm component,
a thumb component,
a lower palm component, and
a wrist component,
wherein each course of the upper palm component is knitted to include a tuck knit
stitch in the course adjacent the upper palm inner edge and each course of the thumb
component is knitted to include a tuck knit stitch in the course adjacent the thumb
inner edge, such that a tuck knit ridge is created along the upper palm inner edge,
around the thumb crotch and along the thumb inner edge as the upper palm component
and the thumb component are knitted sequentially.
[0031] Each of the components is knitted in sequence, as mentioned above and, generally,
as illustrated in Fig.1. Thus, the knitting machine used will, first, knit the one
or more finger components. If only one finger component is required, i.e. in the production
of a mitten, then after that component has been knitted the knitting sequence continues
with the knitting of the upper palm component. If more than one finger component is
to be knitted, the sequence begins with the knitting of the finger components, starting
with the finger component furthest away from the thumb. The knitting sequence continues
with the knitting of the finger components moving closer to the thumb, one finger
component at a time. Thus, in the case of a typical glove with four finger components,
the sequence begins with the component for the little finger, continuing on through
the third finger and middle finger to the index finger. After each finger component
is knitted using the needles selected for this, the knitting process for each finger
component is stopped and, typically, the yarn is cut and bound. The finished knitted
finger component is held in place by holders, weighted down by sinkers and, if further
finger components are required, these are knitted sequentially one at a time using
a different set of needles in the needle bed. When all four fingers are knitted in
this fashion, the knitting machine then knits the upper palm component, picking stitches
from each of the previously knit finger components. After knitting an appropriate
length of the upper palm component, the thumb component is then initiated. Next, the
lower palm component is knitted using all of the needles across the needle bed. Finally,
the knitting machine knits the wrist component to the desired length.
[0032] The gloves of the invention can be knitted using a flat knitting machine which has
a needle selection drum located beneath the knitting bed. Such knitting machines are
well known. The needle selection drum in such machines has a plurality of parallel
grooves in the direction of the drum axis. Needle selection pins, which are rod-like,
of various lengths depending on the knitting requirements, are located in the grooves
in a predetermined arrangement pattern. A two-dimensional representation of the position
of needle selection pins in the grooves of the cylindrical needle selection drum in
the manufacture of the four-fingered grove shown in Fig. 1 is shown in Fig. 3. As
indicated in Fig. 3, the knitting process for the glove begins with the pin arrangement
A (the little finger) and sequentially proceeds through B (Ring finger), C (middle
finger) to D (forefinger). In Fig. 3 E represents the pin arrangement for the knitting
of the upper palm component of the grove, F represents the pin arrangement for the
thumb component, G is the arrangement for the lower palm component and H indicates
the pin arrangement for the wrist component of the glove. In Fig,3, numbers are shown
for each of the pins and these correspond to the numbers of courses to be knitted
for each pin. Beneath the pin arrangement for the thumb component is shown the pin
arrangement for knitting the lower palm component of the glove and, beneath this,
the pin arrangement for knitting the wrist component of the glove. The length of the
round pin, provided in the grooves of the needle selection drum of the knitting machine,
for each portion of the glove (fingers, thumb, palms, wrist) is different and it defines
the number of needles to be activated for each portion. This controls the width of
the knitted component. When one component of the glove has been knitted, the drum
is rotated by one pitch corresponding to the interval between one groove and the next
and the pins located in this next groove are brought into play. When a needle selection
pin in the drum groove pushes up a control jack in which the knitting needle is secured,
the needle jack butt of the needle jack is caused to protrude from an opening in the
needle bed. The control jack, when pushed up by the pin, pushes the needle jack butt
upwards and out of the needle bed. As a carriage moves across the knitting bed, it
contacts all needle jack butts protruding out of the needle bed and so engages those
needles in the knitting process. When the needle moves up the knitting bed, a latch
on the hooked end of the needle opens which allows the needle to hook and hold yarn
and, subsequently, to pull the yarn down as it moves downwards. The yarn is then pressed
by sinkers to complete the stitch and hence advance the fabric formation process.
[0033] We have found that by modifying the conventional glove-knitting process described
above, the machine can be activated to produce the tuck knitted ridge in the regions
of the glove described. The modifications required can be achieved in several ways.
[0034] One first, alternative, modification of the knitting machine components which results
in the knitting of gloves according to the invention requires i) a change to the diameters
of the needle selection pins located in the needle selection drum for the upper palm
component and for the thumb component; and ii) a change to the diameter of the set-up
cam control lever roller which is located in the knitting front carriage. With reference
to i) above, we have found that the needle selection pin for the upper palm section
should be replaced by two new pins (a) and (b); a first (a) having a diameter increased,
from the conventional diameter size of 2.5mm, to 3.07mm-3.08mm and a second (b) having
a diameter reduced, from the conventional diameter size of 2.5mm, to 2mm. Additionally,
the base needle selection pin for the thumb section should be replaced by two new
pins (c) and (d); a first (c) having a diameter increased, from the conventional diameter
size of 2.5mm, to 3.07-3.08mm and a second (d) having a diameter reduced, from the
conventional diameter size of 2.5mm, to 2mm. A two-dimensional representation of a
needle selection pin arrangement which shows the modification to the number and diameters
of pins for the knitting of the upper palm and thumb component is shown in Fig. 4.
The increased height of the needle selection pins (a) and (c) in the drum grooves
will have the effect of raising the needle second in from the edge of the components
directly above higher than is normal in the knitting process which causes both back
bed needle and front bed needle to cross and create a tuck stitch. This will result
in the particular needles in the front bed simultaneously working with the back bed
needles to form a tuck knit stitch at the upper palm edge (crotch) and thumb edge
(crotch). This creates a knitted external ridge at the edge of the knitted component.
It will be understood by the person skilled in the art that if two or even three pins
are modified then the number of tuck knit stitches in the weft increases to form a
higher, more pronounced ridge. The use of the reduced diameter pins (b) and (d) will
result in the avoidance of the working of front bed needles simultaneously with back
bed needles at the upper palm and thumb portions (other than at the edge where the
reinforcement is required).
[0035] With reference to (ii) above, in addition to the modifications of the needle selection
pins described above, a modification of the set-up cam is also required. The set-up
cam, which is located in the knitting front carriage, is capable of movement upwards
and downwards. When the set-up cam is in the upward position the cam works and when
it is in the downward position the cam does not work. The motion of the set-up cam
is controlled by a computer. The set-up cam is normally set to the working position
only during finger tip knitting to create a tuck knit at those areas so as to close
the finger tips and to create a tucked crotch between successive finger components.
The modification of the set-up cam required (in combination with the pin modification
discussed above) to enable the machine to create a tuck knit ridge as described involves
a reduction of the diameter of the set-up cam control lever roller from the normal
size of 5mm to 3.5-3.8mm.
[0036] A second, alternative, modification of the knitting machine components that enables
the machine to create a tuck knit ridge as described involves a principle similar
to that described above in that the needle is caused to raise and the effect of the
set-up cam is reduced. This modification requires a combination of an increase in
the height of the control jack butt on the control jack, a reduction in the height
of the set-up cam control bar, and a reduction in the diameter of the needle selection
pin that slots into the grooves of the selection drum.
[0037] The standard (i.e. normal) height of the butt on the control jack, with finer gauges
above 10, is 3mm. According to this modification, the height of the butt for such
gauges should be increased by 0.1 to 4mm, preferably by 0.5 to 2mm and more preferably
by 1mm. With lower gauge knitting machines, e.g. 5 or 7 gauge, the butt on the control
jack as supplied is 4mm high. According to this modification, the height of the butt
for such gauges should also be increased by 0.1 to 4mm, preferably by 0.5 to 2mm and
more preferably by 1mm.
[0038] The second part of this modification involves resetting the height of the set-up
cam control bar, as mentioned above. The set-up cam control bar in a machine set up
to knit conventional gloves governs the working of the finger tip knitting end and
the finger crotch areas. By reducing the height of the set-up cam control bar the
needles at the edge of the workpiece are activated to form tuck knit stitches. For
all available gauges of knitting machines, the standard height of the set-up cam bar
is 16mm. We have found that, for this modification, the height of the set-up cam bar
should be reduced along the whole of its length by 1 to 8mm, preferably by 2 to 4mm
and more preferably by 3mm, where the set-up cam bar has a height along the whole
of its length of 13mm.
[0039] The third part of this modification involves a reduction in the diameter of the needle
selection pin that slots into the grooves of the needle selection drum. With higher
gauge knitting needles (10, 13, 15 and 18 gauges), the standard needle selection pin
has a diameter of 2.5mm. According to this modification, the diameter of the needle
selection pin will be 0.1 to 1.8mm less than the standard diameter, preferably 0.5
to 1.5mm less and more preferably 1mm less than the standard diameter where the diameter
of the pin will be 1mm. With lower gauge knitting needles (5 or 7 gauge), the standard
diameter of the needle selection pin, as supplied, is 3mm. According to this modification,
for these lower gauge needles, the diameter of the needle selection pin will be 0.1
to 1.8mm less than the standard diameter, preferably 0.5 to 2mm less and more preferably
1mm where the needle selection pin will have a diameter of 2mm.
[0040] A third alternative modification of the machine to enable the formation of a tuck
knit ridge as described is to increase the needle selection pin diameter as discussed
above for the first alternative modification and to reduce the height of the set-up
cam control bar as discussed above for the second alternative modification.
[0041] A fourth alternative modification of the machine to enable the formation of a tuck
knit ridge as described above is to increase the height of the control jack butt as
discussed in the second alternative modification above and to reduce the diameter
of the set-up cam control lever roller as discussed above in the first alternative
modification.
[0042] Each of the alternative modifications discussed above has the effect of raising the
needles, for the edge of the thumb and the upper palm inner edge of the glove, in
the knitting bed in the knitting process such that the back bed needle and the front
bed needle cooperate to create a tuck stitch. In the event that a tuck knit ridge
is desired along the index finger edge of the glove, as mentioned above, then the
appropriate components may be modified accordingly.
Experimental
[0043] Samples of gloves according to the invention having a knitted ridge of one course
modified as a tuck stitch through the thumb crotch as shown in Fig. 5 were compared
to standard knitted gloves.
[0044] A tear test was performed on a cut section of the gloves using a Testometric M250-3CT
testing machine. This machine comprises upper and lower jaws for clamping material
between them. The jaws are moved apart from each other and the force required to break
and tear the sample is measured.
Specimen Preparation
[0045] As shown in Fig 6, a section was cut from each glove along the line C to E and along
the line E to D as shown in the Figure such that the section contains part of the
index finger, part of the thumb and the thumb crotch of the glove. The sample was
10mm wide by 90mm long,
[0046] The thumb part of the cut section was clamped in the upper jaw of the testing machine
at point B which lies 5cm from the crotch (point E) and the finger part of the cut
section was clamped in the lower jaw of the testing machine at point A which lies
5cm from the crotch (point E).
Method
[0047] A load cell of 300kg was used for testing. The force is applied, by the testing machine,
to the specimen at a constant speed of 100 ± 10mm/minute. The breaking force is recorded
at the break point. Four samples of each of the standard glove and the glove of the
invention were tested. The results for each are shown in Figs. 7 and 8, where Fig.
7 shows the results obtained for the standard glove and Fig. 8 shows the results obtained
for the glove of the invention.
[0048] The mean force required to tear and break the specimen cut from the standard glove
was measured as 94N. The mean force required to tear and break the specimen cut from
the glove of the invention was measured as 104N, giving an increase in strength in
the glove of the invention of approximately 10%.
[0049] The higher force required to tear and break the specimen cut from the glove of the
invention indicates the increased strength provided to the glove by the tuck knit
