TECHNICAL FIELD
[0001] The present invention generally relates to the field of garments, and in particular
to the manufacturing of disposable garments.
BACKGROUND
[0002] Protective garments, such as disposable gowns for medical staff and patients, may
be produced from a sheet of a flexible material, such as e.g. a plastic film, that
is cut into parts and joined into the desired design. A drawback with this technology
is however that the manufacturing process generally involves a large number of complex
processing steps, which often requires manual intervention and handling.
[0003] With an ever-increasing demand for disposable protective garments there is a need
for improved technologies that allow for a more efficient manufacturing and reduced
manufacturing costs.
SUMMARY
[0004] It would be advantageous to achieve a technology overcoming, or at least alleviating
the above-mentioned drawback. In particular, it would be desirable to provide an improved
and more cost-effective method for manufacturing disposable garments.
[0005] To better address this concern, a method, a garment and a system having the features
defined in the independent claims are provided. Preferable embodiments are defined
in the dependent claims.
[0006] Hence, according to a first aspect, there is provided a method for manufacturing
disposable upper body garments having sleeves and a front portion. According to the
method, a first sleeve film and a second sleeve film are provided on a respective
edge portion of a main film, wherein the edge portions are separated by a centre line
extending in a longitudinal direction. The method comprises joining the sleeve films
to the main film along at least part of an outline defining the sleeves of the garments,
and defining at least part of the remaining outline of the garments by punching through
the films.
[0007] Specifically, the method may comprise feeding the main film in a longitudinal direction,
wherein the first and second edge portions of the film are arranged transversely opposing
each other on a respective side of the centre line. An assembly may be formed comprising
the first sleeve film and the second sleeve film arranged on the upper surface of
the main film, wherein the first sleeve film is arranged on the first edge portion
of the main film and the second sleeve film is arranged on the second edge portion
of the main film. For a first one of the garments, the first sleeve film may be welded
to the main film along at least part of an outline defining the sleeves of the first
one of the garments. For a second one of the garments, the second sleeve film may
be welded to the main film along at least part of an outline defining the sleeves
of the second one of the garments. Further, the method may comprise a step of punching
through the assembly to define a neck opening of the garments, and punching through
the assembly along an outline of the first one and the second one of the garments.
[0008] According to a second aspect, a disposable upper body garment manufactured by the
method according to the first aspect is provided.
[0009] According to a third aspect, a system for manufacturing of disposable upper body
garments according to the first and second aspects is provided.
[0010] The present inventive concept is based on the realisation that by arranging the first
and second sleeve films on the edge portions of the main film, and using the sleeve
films to form the sleeves of the resulting garment, the manufacturing of the garment
can be more efficient. Several advantages may be associated with the present aspect.
Firstly, the sleeve films allow for the front portion of the garment to be provided
with sleeves in a relatively easy and efficient way. The sleeves may be formed by
joining the sleeve films and the main film along lines defining the armpit to arm
seams of the garment and, optionally, the shoulder to arm seams, and punching the
films at the arm opening so as to define the outline of the sleeves. This can be done
"on the fly" as the film assembly is feed forward in the longitudinal direction. Secondly,
the size of the sleeves can easily be determined by varying the width of the sleeve
films, wherein a wider sleeve film allows for a wider sleeve and vice versa. Thus,
the design of the sleeves can be varied by modifying the width of the sleeve films,
the position of the welds joining the films, and the cuts or perforations defining
the outline of the sleeves. Thirdly, the garments can be manufactured in a roll-to-roll
process, which advantageously allows for increased productivity and reduced waste,
especially compared to processes requiring individual and manual handling of the garments.
[0011] In the present specification, the term "disposable" may refer to a garment intended
to be thrown away after use. This may also be referred to as one-use or expendable
and should generally be understood as a garment that is not intended to be re-used
multiple times.
[0012] The term "upper body garment" generally refers to an item of clothing suitable for
the upper part of the body, in particular the trunk and the arms. The garment may
also be referred to as a gown or an apron, such as a sleeved apron (with long or short
sleeves). Preferably, the garment is a protective garment, such as a medical garment
providing a barrier between patient and professional.
[0013] By "film" may be understood a material in the form of a thin and flexible sheet,
preferably stored and supplied on a roll. The film may for example be formed of plastic
or paper, or another material worked in a manner analogous to plastic. Preferably,
the film is formed of polyethylene or polylactic acid. The first sleeve film, the
second sleeve film and the main film may be formed of the same material or of different
materials.
[0014] The main film, or lower film in the assembly may generally be referred to as having
a length extension in the longitudinal direction, i.e., the feeding direction during
the manufacturing, and a width in a lateral direction, i.e., a direction orthogonal
to the longitudinal direction. Similarly, the first and second sleeve films may have
a length extension in the longitudinal direction and a width in the lateral direction.
Preferably, each of the first and second sleeve films may have a width that is smaller
than half the width of the main film. In other words, the first and second sleeve
films may be separated by a distance when arranged on the main film, such that a centre
region of the main film is not covered by any of the first and second sleeve films.
[0015] The layers of the assembly, i.e., the first/second sleeve film and the main film,
may be selectively joined together in certain regions or along certain lines so as
to form the sleeves of the garment. The joining may for example be achieved by applying
pressure or heat. In some examples, the films may be joined by welding or gluing.
Welding may be advantageous in that no additional components, such as e.g. glue, may
be required. Instead, the joint may be formed by heating the material of the films
to the point of melting.
[0016] By "punching" is generally meant the process of piercing a hole through the assembly.
Thus, the punching may result in for example a perforation, i.e., a row of holes punched
in the assembly so that a part can be torn off more easily, or a cut-out where a part
of the assembly is removed in its entirety.
[0017] By "sleeve" is generally meant the part of the garment that wholly or partly covers
a person's arm. Preferably, the sleeve is configured to wholly enclose or encircle
a part of the arm, but not necessarily the entire length of the arm. By "front portion"
is generally understood the part of the garment that is intended to wholly or partly
cover the front of the wearer's body, i.e., to be arranged anterior to the body. However,
the front portion may be suitable to be worn posterior to the body as well, depending
on the desired use. The present aspect allows for garments to be produced, which may
be open either in the back or in the front. By "neck opening" is generally referred
to an opening intended to receive the head of the user during use.
[0018] According to an embodiment, the first and second sleeve films may be formed of the
main film. The sleeve films may for example be cut out from the main film in a prior
step and arranged on the upper surface of the main film to form the assembly.
[0019] Alternatively, the first and second sleeve films may be formed by folding the main
film onto its upper surface. This may be achieved by folding a first longitudinal
edge and a second longitudinal edge of the main film towards a centre of the main
film, wherein the longitudinal edges are transversely opposed to each other. Forming
the assembly by folding the edges of the main film is advantageous in that the number
of components involved in the manufacturing process may be reduced. In other words,
there is no need for handling the sleeve films as separate components. Instead, the
sleeve films may be provided by adding a folding step to the process rather than adding
separate films. A further advantage is that the fold line may serve as a joint between
the sleeve films and the main film, thereby reducing the welding. With this, it may
suffice to weld together the sleeve films and the main film along the underarm seam,
i.e., the seam running from the armpit to the arm opening of the sleeve.
[0020] Hence, the method may comprise welding the first/second sleeve film to the main film
to form the underarm seam, whereas the first/second sleeve film is already joined
to the main film along shoulder to arm seam. The sleeve opening and the front portion
of the garment may then be defined by perforating or cutting the assembly.
[0021] Should the first/second sleeve films not be formed by folding the main film but provided
as separate films arranged on the main film, the films may also be joined together
along an upper arm seam, i.e., the shoulder to sleeve opening seam.
[0022] According to an embodiment, the first one and the second one of the garments may
be arranged adjacent to each other in the longitudinal direction. Preferably, the
opening of the sleeve of a first one of the garments is arranged next to the front
portion of a second one of the garments such that both the arm opening and the front
portion can be defined by a single, common cut or perforated line. With this arrangement
the waste may be reduced.
[0023] The inventive concept allows for a continuous, on-the-fly production of garments
that are arranged in an alternating pattern in the assembly. With every second garment
having the sleeves formed from the first sleeve film and the intermediate garments
having the sleeves formed from the second sleeve film, an alternating, compact and
relatively surface-effective layout can be obtained, allowing for reduced waste of
material.
[0024] According to an embodiment, the remaining material between consecutive garments may
be cut out and removed from the assembly. The remaining assembly may thus comprise
only garments arranged side by side in an alternating manner, wherein the sleeve opening
of a first garment is attached to the side of the body of a neighbouring garment.
Removing the remaining material between the garments may reduce the waste at the user's
end and allow for the array of garments to be rolled up and stored in a roll having
a reduced weight.
[0025] Alternatively, the garments may be separated from each. This allows for the garments
to be arranged in a stack rather than on a roll.
[0026] In an embodiment, the assembly comprising a plurality of garments may be re-reeled
into a roll. Optionally, the assembly may be folded along the longitudinal direction
prior to being formed into a roll. The resulting product may thus be protective gowns
on roll, which facilitates handling and transport and allows for an improved user
experience.
[0027] It is noted that embodiments of the invention relate to all possible combination
of features recited in the claims. Further, it will be appreciated that the various
embodiments described for the manufacturing method according to the first aspect are
all combinable with embodiments of the product and system as defined in the second
and third aspects.

DETAILED DESCRIPTION
[0030] The present aspects will now be described more fully hereinafter with reference to
the accompanying drawing, in which currently preferred embodiment are shown. This
invention may, however, be embodied in many different forms and should not be construed
as limited to the embodiments set forth herein; rather, these embodiments are provided
for thoroughness and completeness, and to fully convey the scope of the present aspects
to the skilled person.
[0031] A main film 100 and a first and second sleeve film 110, 120 according to an embodiment
will be described with reference to figure 1. The main film 100, which for example
may be a plastic film of polyethylene or polylactic acid, may be feed in a longitudinal
direction F during the manufacturing of disposable upper body garments according to
the inventive concept. The longitudinal direction F may also be referred to as a feeding
direction. The feeding of the main film 100 may for example form part of a roll-to-roll
processing, in which the main film 100 may be provided from a roll and be re-reeled
to create an output roll after processing.
[0032] The main film 100 may comprise two transversely opposing edge portions 101, 102,
or longitudinal portions 101, 102, that have a length extension in the longitudinal
direction F and are separated by a centre line C extending along the longitudinal
direction F. Further, the main film 100 has an upper surface and an opposing lower
surface, facing away from the upper surface.
[0033] As indicated in the present figure, a first sleeve film 110 and, preferably, a second
sleeve film 120 may be arranged on the upper surface of the main film 100. The sleeve
films 110, 120 may have a similar configuration as the main film 100, with the difference
that the sleeve films 110, 120 may have a width that is smaller than the width of
the main film 100 (as seen in a direction orthogonal to the longitudinal direction
F). In the present example, each of the sleeve films 110, 120 may have a width that
is less than half the width of the main film 100 such that they, when arranged side
by side on the main film 100, do not cover the full width of the main film 100. The
first sleeve film 110 may be arranged on or above the first edge portion 110 and the
second sleeve film 120 may be arranged on or above the second edge portion 120. As
shown in figure 1, the sleeve films 110, 120 may be arranged to cover the respective
edge portions 101, 102 all the way out to the longitudinal edges of the main film
100.
[0034] The sleeve films 110, 120 may be formed of the same type of material as the main
film 100, i.e. for example polyethylene or polylactic acid. In in the present example,
the sleeve films 110, 120 are formed from the main film 100 by folding the longitudinal
edges of the main film 100 onto the upper surface of the main film 100. Thus, the
longitudinal edges indicated in figure 1 may represent the fold line at which the
main film 100 has been folded onto itself.
[0035] Figure 2 shows the assembly of figure 1 after definition of a first and a second
disposable upper body garment 10, 20. According to the present embodiment, the first
and second garment 10, 20 have been defined beside each other in the feeding direction,
and turned upside-down relative to each other such that the sleeves 11 of the first
garment 10 are formed from the first sleeve film 110 and the sleeves 12 of the second
garment 20 are formed from the second sleeve film 120. The first and second garments
10, 20 are arranged adjacent to each other such that an arm opening of the first garment
10 abuts the front portion 22 of the second garment 20.
[0036] In case the sleeve films 110, 120 are formed by a folded portion of the main film
100, it may suffice to join the sleeve films 110, 120 to the main film 100 along a
portion of the outline 13, 23 defining the underarm seam. Due to the folding, the
sleeve film 110, 120 is already joined to the main film 100 along the shoulder to
arm seam. However, should the sleeve film 110, 120 be provided as a separate item,
i.e., not be formed from a folded part of the main film 100, it may be necessary to
weld the sleeve film 110, 120 to the main film 100 along the shoulder to arm seam
as well.
[0037] According to the embodiment illustrated in figure 2, the first garment 10 may be
defined by welding the first sleeve film 110 to the main film 100 along the portion
of the outline 13 corresponding to the underarm seams of the sleeves 11, whereas the
second garment 20 may be defined by welding the second sleeve film 120 to the main
film 100 along the portion of the outline 23 corresponding to the underarm seams of
the sleeves 21. In a further processing step, the assembly may be punched along the
remaining part of the sleeve outline corresponding to the arm openings 18, 28 of the
sleeves 11, 21 and along the outline 16, 26 corresponding to the sides of the front
portions 12, 22. The punching may in this example result in the remaining portion
of the assembly that is arranged between neighbouring garments 10, 20 being cut out
and removed, and the portion 18, 28 of the outline separating the arm openings from
the neighbouring garment being perforated to allow the garments to be separated later,
for example by a user. As a result, the assembly may comprise a sequence of alternatingly
arranged garments 10, 20 that are attached to each other by perforations at the arm
openings 18, 28. The sleeve film that is not used to form the sleeves of a garment,
i.e., the second sleeve film 120 of the first garment 10 and the first sleeve film
110 of the second garment 20, may be unfolded during use to form part of the front
portion 12, 22 of the garment.
[0038] The neck openings 14, 24 may be formed by cutting out a corresponding portion of
the assembly. It is appreciated that the neck opening 14, 24 in an alternative example
may be defined by perforating the assembly along an outline of the neck opening 14,
24 so as to allow for the material of the neck opening 14, 24 to be removed at a later
stage, for example by a user.
[0039] Figure 3 is a schematic side view of a system for manufacturing a disposable upper
body garment according to an exemplifying embodiment. The manufacturing process and
the resulting garments may be similarly configured as the embodiments discussed above
in connection with figures 1 and 2. The system 200 may comprise a feeding mechanism
210 for feeding the main film 100, or lower film 100, in the longitudinal, feeding
direction F (indicated by an arrow in figure 3). The main film 100 may for example
be provided from a roll by means of the feeding mechanism 210. The feeding mechanism
210 may further be configured to provide the first sleeve film 110 and the second
sleeve film 120, which in the present embodiment and like the main film 100 may be
provided from a roll.
[0040] The sleeve films 110, 120 may be arranged on the upper surface of the main film 100
by means of a downstream assembling mechanism 220. The assembling mechanism 220 may
for example comprise a guiding means for aligning the first sleeve film 110 with the
first transversely opposing edge 101 of the main film 100 and the second sleeve film
120 with the second transversely opposing edge 102 of the main 100. The resulting
assembly may be similar to the structure shown in figure 1.
[0041] The system 200 may further comprise a welding tool 230 configured to provide the
welds 13, 23 defining the sleeves 11, 21 of the garments 10, 20. The welding tool
230 may for example comprise a rotating cylinder selectively applying heat to regions
of the passing assembly, the regions extending along an outline of the sleeves 11,
12 corresponding to e.g. the underarm seam and the shoulder to arm seam.
[0042] The assembly may also pass through a cutting tool 240 for cutting out the neck openings
14, 24. The cutting tool 240 may for example comprise a rotating cylinder configured
to punch out portions of the assembly that define the neck openings 14, 24. Additionally,
the cutting tool 240 may be further configured to cut out also the regions of the
assembly arranged between two neighbouring garments 10, 20. Thus, the result as the
assembly passes through the cutting tool 240 may be a plurality of garments 10, 20
that are joined to each other at the interface between the arm openings and the lower
parts of the front portions 12, 22.
[0043] A punching tool 250 may be added to the system 200 so as to provide a perforated
outline defining the arm openings 18, 28 of the sleeves 11, 21. The punching tool
250 may be similarly configured as the cutting tool 240, and hence comprise a rotating
cylinder for cutting through the assembly as it passes by.
[0044] It should be noted that the above cutting tool 240 and punching tool 250 may be provided
as two structurally distinct devices along the processing line, or as an integrated
tool capable of defining both the neck openings 14, 24 as well as the outline of the
garments 10, 20. Thus, the cutting tool 240 and the punching tool 250 may refer to
a single tool, such as a punching tool, for cutting out the neck openings 14, 24 as
well as the remaining portions between the garments 10, 20. Further, such a tool may
also be configured to either perforate the assembly along the arm opening 18, 28 or
to cut through the assembly so as to separate the garments 10, 20 from each other.
[0045] The resulting product may then be fed to a finishing mechanism 260 at which it for
example may be folded along the centre line and re-reeled into an output roll.
[0046] Figure 4 shows a top view of a system 200 according to an embodiment, which may be
similarly configured as the system illustrated in connection with figure 3. Thus,
the system may comprise a feeding mechanism 210 for feeding the main film 100 along
the longitudinal direction of the film, an assembly mechanism 220 for arranging the
sleeve films 110, 120 on the respective edge portions 101, 102 of the main film 100,
a welding tool 230 for joining the sleeve films 110, 120 to the main film 100 to define
the sleeves 13, 23, and a punching or cutting tool 240 for defining the neck openings
14, 24 and at least part of the remaining outline of the garments 10, 20. The punching
tool 240 may for example be configured to cut out the neck portions 14, 24 and the
portions between the garments 10, 20 (indicated by the crosshatched regions in figure
4). Finally, the assembly may be stored on a roll by means of a finishing mechanism
260.
[0047] A difference to the embodiment discussed above in connection with figure 1 may be
that the first and second sleeve films 110, 120 according to the present embodiment
may be formed by folding the edges 101, 102 of the main film 100 onto the upper surface
of the main film 100. This may be performed by the assembly mechanism 220, which thus
may be a folding mechanism 220 providing an assembly similar to the one illustrated
in connection with figure 1. After the folding of the main film 100, an assembly is
formed, in which the first and second sleeve film 110, 120 cover the edge portions
of the main film 100 and are separated from each other along a centre line extending
along the longitudinal direction of the main film 100. As a consequence, the sleeve
films 110, 120 are already joined to the main film 100 along the upper seam, i.e.,
the shoulder to arm seam by the fold and it may therefore suffice if the welding tool
230 applies a joining weld to the underarm seam, i.e., the armpit to arm seam.
[0048] Figure 5 is a flow chart illustrating a method for manufacturing disposable upper
body garments having sleeves and a front portion similar to the garments described
with reference to figures 1 to 4. The method may comprise feeding 1 a main film in
a longitudinal direction, forming 2 an assembly comprising a first sleeve film and
a second sleeve film arranged on an upper surface of the main film, and more particular
such that the first sleeve film is arranged on a first longitudinal edge portion of
the main film and the second sleeve film is arranged on a second edge portion of the
main film. This may for example be performed by folding the longitudinal edges of
the main film onto its upper surface. Further, the method may comprise welding 3 the
first sleeve film to the main film along an outline defining the sleeves of a first
one of the garments, and welding 4 the second sleeve film to the main film along an
outline defining the sleeves of the second one of the garments, cutting out 5 a neck
opening of the first one and the second one of the garments, and punching through
6 the assembly along an outline of the first one and the second one of the garments.
In some examples, the method may comprise removing 7 a remaining portion of the assembly
arranged between the first and second ones of the garments. In an optional step, the
assembly may be folded 8 along the longitudinal direction before it is rolled 9 into
an output roll.
[0049] The person skilled in the art realises that the present invention by no means is
limited to the preferred embodiments described above. For example, the welding and
punching may be performed in different order, in which the outline of the garments
for example is defined by perforating or punching the assembly prior to the welding
of the seams, or in a same processing step. Further, the outline may in addition to
welding of the sleeves be defined by perforations only, by cutting only, or a combination
of both. Additionally, variations to the disclosed embodiments can be understood and
effected by those skilled in the art in practising the claimed invention, from a study
of the drawings, the disclosure, and the appended claims. In the claims, the word
"comprising" does not exclude other elements or steps, and the indefinite article
"a" or "an" does not exclude a plurality. The mere fact that certain measures are
recited in mutually different dependent claims does not indicate that a combination
of these measures cannot be used to advantage. Any reference signs in the claims should
not be construed as limiting the scope.
