BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to cleaning devices, and more specifically to a cleaning
device for fabrics that is capable of picking up and retaining for disposal various
debris located on a fabric surface.
2. Discussion of the Related Art
[0002] When cleaning fabric surfaces, often times mechanical vacuum cleaning devices are
utilized in order to effectively remove dirt, dust, and other debris from the fabric
surface. However, due to the often large and cumbersome construction of these types
of mechanical vacuum fabric cleaning devices, these devices are often not suitable
for use in certain situations where the fabric surface to be cleaned is relatively
small, or is positioned in a difficult to access location. In addition, for various
instances of spot cleaning certain fabric surfaces, a large mechanical cleaning device
is often impractical for the particular cleaning task.
[0003] Therefore, in order to provide a lightweight cleaning device that can be utilized
as an alternative to larger mechanical vacuum cleaning devices for these types of
situations, various types of alternative cleaning devices and brushes have been developed.
For example,
Tsuruzawa U.S. Patent No. 3,747,152 discloses a cleaning brush with dust removing and collection means. The device includes
a rotatable or slidable brush that is mounted to a housing that can be grasped by
an individual to move the brush across a surface to be cleaned. The movable brush
is formed with a number of bristles which are oriented generally oppositely to bristles
on a pair of brush members disposed on the housing surrounding the brush. The bristles
on the movable brush pick up dirt from the surface by contacting the dirt as the brush
is moved across the surface. The bristles then rotate into engagement with the bristles
on the brush members in the housing to dislodge the dirt from the movable brush. The
dirt and dust dislodged by the brush members is then collected within the movable
brush opposite the bristles for later removal through an opening in the housing to
which the movable brush is mounted.
[0004] However, this device has certain shortcomings in that the ability of the brush to
effectively retain any dirt, dust or other debris picked up by the movable brush is
determined by the contact of the bristles on the brush with the bristles of the brush
members. Because the movable brush necessarily has to move into contact with the brush
members from the exterior of the device, the brush can dislodge the dirt, dust and
other debris from the movable brush before the dirt is located within the brush housing.
Furthermore, for that component of the dirt, dust and other debris that is actually
contained within the housing as a result of the proper operation of the device, the
debris must be dispensed by inverting the device and shaking the housing such that
the debris moves through an opening in the housing, which is a highly inefficient
manner to remove the dirt from the device.
[0005] Further,
US Patent No. 2,460,183 discloses a fabric cleaning device comprising: a housing having a lower portion and
an upper portion, the upper portion being spaced above the lower portion by a pair
of opposed supports and end walls in order to define a recess between the side supports
and end walls; a first cleaning member movably secured to the housing within the recess;
a second cleaning member movably secured to the housing within the recess; and a debris
collection chamber connected to the housing and spaced from the recess.
[0006] Therefore, it is desirable to develop a lightweight, manually operable fabric surface
cleaning or sweeping device that engages dirt, dust and other debris picked up off
of a fabric surface in a manner which more effectively removes the debris from the
surface and deposits this debris within a collection chamber positioned in the device.
Further, it is also desirable to develop a fabric sweeper cleaning device in which
the dust or debris collected by the device can be more easily dispensed of using the
separate collection chamber.
SUMMARY AND OBJECTS OF THE INVENTION
[0007] According to a primary aspect of the present invention, a fabric cleaning and/or
sweeping device is provided with a housing that includes a pair of movable cleaning
members secured within a recess in the housing such that each member is engageable
with the fabric to be cleaned and with the opposed fabric cleaning member and having
the features of the appended claim 1.
[0008] The movable cleaning members rotate with respect to the housing as the cleaning device
is moved over the fabric surface, and pick up any dust, dirt or other debris on the
fabric surface. The movable cleaning members are secured within the housing in a manner
which enables the members to rotate independently of one another, but also that the
cleaning members selectively come into contact with one another. When the cleaning
members contact one another, the members effectively act as a cleaning mechanism for
one another, urging the dust, dirt and other debris off of the opposite member and
into a collection chamber for the device. The members can easily pick up dust, dirt
and other debris from the fabric surface due to the construction of the cleaning members
which include an outer surface formed of a material that readily attracts pet hair,
crumbs, dust, lint, allergens and other materials present on the fabric surface. The
materials are also chosen to be somewhat flexible such that the material, in addition
to being cleaned by the material positioned on the opposed rotatable member, can be
further cleaned of the dirt, dust and other debris picked up by the material as a
result of the contact of the material on each cleaning member with the housing.
[0009] Preferred embodiments are defined in the dependent claims.
[0010] According to the present invention, the housing includes a dirt collection chamber
with an open lower end that is in communication with the space within which the rotatable
members are positioned such that the dirt and dust picked up by the cleaning members
is diverted through the housing into the collection chamber. In one embodiment, the
chamber is preferably removably retained within the housing until such time as the
chamber becomes filled with dirt, dust and other debris picked up by the cleaning
members. The chamber can then be removed, emptied and/or replaced in order to ready
the device for additional cleaning.
[0011] According to still another aspect of the present invention, the housing within which
the cleaning members and the collection chamber are positioned is designed to enable
easy handling and use by an individual to clean a fabric surface. Additionally, the
housing is formed with a minimum of parts, which can each be formed of lightweight
materials that are relatively low cost and easy to manufacture into the housing components.
[0012] Numerous other aspects, features and advantages of the present invention will be
made apparent from the following detail description taken together with the drawing

DETAILED DESCRIPTION OF THE INVENTION
[0015] With reference now to the drawing figures in which like reference numerals designate
like parts throughout the disclosure, a fabric cleaning or sweeping device constructed
according to the present invention is indicated generally by the reference number
10 in Fig. 1. The fabric sweeper or device 10 preferably includes a housing 11 with
a base portion 12 and a handle portion 14 extending upwardly from the base portion
12. When in use, the base portion 12 of the device 10 is positioned on a fabric surface
16 and moved in a direction generally perpendicularly to the long axis 18 of the device
10 in order to pick up debris 20 disposed on the fabric surface 16.
[0016] Referring now to Figs. 1-6, the device 10 is formed with an outer housing 22 and
an inner housing 24. Both the outer housing 22 and inner housing 24 are formed of
a generally rigid material, that is also preferably lightweight, in order to enable
the device 10 to be easily manipulated by an individual's hand 26, as best shown in
FIG. 1. Most preferably, each housing 22 and 24 is constructed of a plastic material,
such that the shape of the respective housings 22 and 24 can be easily modified as
desired, and formed in a conventional plastic molding process, e.g., injection molding.
[0017] The outer housing 22 includes a lower opening 28 within which the inner housing 24
is located, and an upper opening 30 positioned generally opposite the lower opening
28. The upper opening 30 can have any desired shape, but is preferably rectangular
in shape in order to accommodate a collection chamber or bin 32 therein. The bin 32
includes a handle 34 at one end to facilitate the removal of the bin 32 from within
the upper opening 30 in the outer housing 22. The bin 32 is also formed of a generally
lightweight material, such as a plastic material, and includes a wide, closed end
36 at the top of the bin 32, and a narrow open end 38 at the bottom of the bin 32.
Inwardly tapering end walls 40 extend between the closed end 36 and open end 38 at
each end of the bin 32, and are joined by sidewalls 42. The side walls 42 are integrally
formed with the end walls 40 and include a number of open sections 44 spaced therealong.
The open sections 44 allow an individual to view the interior of the bin 32 in order
to determine how much debris 20 has been collected therein. The open sections 44 are
preferably enclosed by a transparent material 46 that can extend from one side of
the open end 38 over the adjacent side wall 42, over the top of the bin 32 to form
the closed end 36, and down over the opposed side wall 42. In this embodiment, the
transparent material 46 allows an individual to view the interior of the bin 32 regardless
of whether the bin 32 is positioned within or removed at least partially from the
upper opening 30 in the device 10. Additionally, to provide a more aesthetically pleasing
appearance to the device 10, the closed end 36 of the bin 32 can be formed of material
similar to the material forming the housing 22 to provide a more seamless appearance
between the closed end 36 of the bin 32 and the handle portion 14 of the device 10.
[0018] Referring now to Figs. 4-6, the inner housing 24 includes a lower portion 48 and
an upper portion 50. The lower portion 48 extends outwardly to conform to the shape
of the lower opening 28 in the outer housing 22, and is fixedly secured to the outer
housing 22 by suitable fasteners 52. The upper portion 50 is spaced above the lower
portion 48 by a pair of opposed supports 54 and end walls 55, preferably integrally
formed between the lower portion 48 and the upper portion 50, in order to define a
recess 56 between the side supports 54 and end walls 55. The upper portion 50 also
includes a central opening 58 having lower edges 80 that extends completely through
the upper portion 50 and allows communication between the recess 56 and the narrow
open end 38 of the bin 32. To keep the device 10 relatively lightweight, the inner
housing 24 is formed of a suitable lightweight material, such as a plastic material.
[0019] The recess 56 also houses a pair of cleaning members 60 and 61. The members 60, 61
are generally semi-cylindrical in shape, such that each member 60, 61 includes a curved
surface 62, and a pair of arcuate end walls 64. Each end wall 64 includes a protrusion
66 extending outwardly therefrom in which is defined a bore 68 that receives a fastener
70 in order to rotatably secure each end wall 64 to the adjacent end wall 55 of the
recess 56. Further, the materials utilized to form the cleaning members 60, 61 are
selected to maintain the overall light weight for the device 10, such that preferred
materials for the cleaning members 60, 61 can include various lightweight metals and
plastics.
[0020] Each cleaning member 60, 61 also includes a layer of cleaning material 72 secured
to the member 60, 61 on the curved surface 62 opposite the end wall 64. The material
72 can be selected from any suitable material capable of picking up and retaining
various dirt, dust, pet hair, crumbs, lint and other allergens from a fabric surface
16 such as a number of teeth disposed, and possibly integrally formed on each member
or a material secured to the members 60, 61. Preferably, the material is formed of
a cloth-like material, with a particularly preferred material being an unidirectional,
fabric, such as velour. The layer of cleaning material 72 is secured to the curved
surface 62 of the cleaning members 60, 61 in any suitable manner, but is preferably
fixedly secured to the curved surface 62 by an adhesive.
[0021] The cleaning members 60, 61 are secured within the recess 56 such that the layer
of cleaning material 72 on each member 60, 61 extends below the lower portion 48 of
the inner housing 24 and into contact with a fabric surface 16 over which the device
10 is moved. Each member 60, 61 is rotatable within the recess 56 between a first
position where an inner side 74 (e.g., Fig. 8) is rotated into contact with an annular
shoulder 76 (e.g., Fig. 8) formed on the upper portion 50 of the inner housing 24
adjacent the opening 58, and a second position where an outer side 78 (e.g., Fig.
8) of each member 60, 61 is rotated into contact with the upper portion 50 adjacent
the corresponding side support 54. Additionally, the thickness of the layer of cleaning
material 72 on each member 60, 61 is selected to enable the material 72 on each member
60, 61 to contact the material 72 on the opposed cleaning members 60, 61 for a purpose
to be described.
[0022] In operation, referring now to Figs. 7-9, the device 10 is placed against and moved
across a fabric surface 16, and the cleaning members 60, 61 each rotate in a clockwise
direction when the device 10 is moved in a direction indicated by arrow A in Fig.
7. As the members 60, 61 rotate in the clockwise direction, the layer of cleaning
material 72 on each member 60, 61 contacts the debris 20 on the fabric surface 16
and picks up the debris 20 such that the debris 20 remains on the cleaning material
layer 72. The device 10 is continually moved in the direction indicated by arrow A
until the cleaning members 60, 61 are moved into the position shown in Fig. 7.
[0023] At this point, the device 10 is moved in the opposite direction indicated by arrow
B in Fig. 8, such that members 60, 61 rotate in a counterclockwise direction. In doing
so, the cleaning material layer 72 on the inner side 74 of member 60 contacts the
cleaning material layer 72 adjacent the inner side 74 of cleaning member 61. As the
respective layers 72 move past and contact one another, the debris 20 on the member
61 is removed and pushed through the central opening 58 in the upper portion 50 into
the open end 38 of the bin 32. The debris 20 engaged between the members 60, 61 is
continually urged upwardly into the opening 58, and cannot fall back on the surface
16 due to the close spacing of the members 60, 61. At the same time, the cleaning
material layer 72 spaced from the inner side 74 of member 61 comes into contact with
the fabric surface 16 in order to pick up additional debris 20 from the surface 16.
Movement in the direction indicated by arrow B is continued in this manner until,
as best shown in Fig. 9, the position of the cleaning members 60, 61 are essentially
reversed from Fig. 7. From the position shown in Fig. 9, the device 10 is again moved
in a direction indicated by arrow A in Fig. 7 such that the inner side 74 of cleaning
member 61 comes into contact with and cleans the debris 20 off of the cleaning material
72 of cleaning member 60, which picks up debris 20 from the surface 16 as it is moved.
This process can be repeated as many times as necessary in order for the cleaning
members 60, 61 to remove all of the debris 20 off of the fabric surface 16.
[0024] The removal of the debris 20 from the cleaning material layer 72 on each cleaning
member 60, 61 is further facilitated by the presence of the debris diverting edge
80 formed on the upper portion 50 of the inner housing 24 on each side of the central
opening 58. The edges 80 on each side of the opening 58 contact the cleaning material
layer 72 on the respective cleaning members 60, 61 when the members 60, 61 move into
the positions shown in FIGS. 7 and 9 to assist in diverting and removing the debris
20 from the cleaning material 72. The edges 80 contact the layers 72 on the members
60, 61 to compress the layers 72 and scrape or otherwise direct the debris 20 from
the layers 72 into the opening 58. Continued motion of the members 60, 61 moves the
layers 72 along the edges 80 to remove additional debris 20 from the members 60, 61.
[0025] After the debris 20 has been removed from the fabric surface 16, an individual can
remove and replace the bin 32, if necessary, or can utilize the device in order to
remove debris 20 from an additional fabric surface or surfaces 16. In addition, as
opposed to the bin 32 being designed for removal and disposal separately from the
device 10, the entire device 10 can be designed to be disposed once the bin 32 has
been filled with debris 20 removed from one or more fabric surfaces 16.
[0026] Additionally, separate from the previously described embodiments, other modifications
to the device 10 are also contemplated as within the scope of the invention. For example,
the chamber or bin 32 can be integrally formed with the outer housing 22, such that
the entire device is disposable. Also, the chamber 32 can include or be formed of
a hair or lint attracting material, such as a strip of a tacky material or a hook
and loop material to trap any lint, hair or other debris contacting it. Also, the
opening 58 in the lower housing 24 could be moved to one side or the other of the
lower housing 24, along with a corresponding shift in the location of the chamber
32.
[0027] Fig. 10 shows an alternative device 110. The device 110 has a housing 110a with base
portion 112 and a handle portion 114 preferably connected by an adhesive or heat staking.
The device cleans the surface along axis 118. The handle portion 114 preferably has
a top 111, a first side 113a, an opposing second side 113b, a front side 113c, and
back side 113d. The first side and the second side have grooves 115a, 115b for receiving
the user's hand and fingers. The grooves allow the user to comfortably grip a handle
portion. Fig. 11 shows the underside of the device 110. As seen in Fig. 11 the base
portion 112 is configured to receive cleaning members 160, 161. The cleaning members
are preferably covered with cleaning material 172a, 172b such as an unidirectional
velour. The cleaning members 160, 161 are semi-circular rollers such as those described
above. In this embodiment, the rollers 160, 161 are attached to the base portion 112
with fasteners 170a, 170b and 170c, 170d located at each end of the roller. In between
the rollers is a central opening 158. In this embodiment, fasteners 170a, 170b are
preferably constructed of two main elements-for example, protrusions 166a and 166b
that are respectively received in the cavities 168a and 168b for roller 161. Similarly,
roller 160 has fasteners 170c, 170d that include protrusions 166c and 166d that are
respectively received in the cavities 168c and 168d.
[0028] As shown in Figs. 12-15, handle portion 114 has a top 121 that is preferably smooth
and rounded. The sides 113a, 113b, 113c, 113d preferably have rounded corners as shown.
[0029] Figs. 16 and 17 show the base portion 112 of the device 110 with the rollers removed.
When the rollers are on place, they fit into fastening clip cavities 150a-150d. Handle
portion 114 and base portion 112 are connected and/or aligned at points 151 as shown.
In one embodiment, ribs may be present (on either portion) to help align the handle
and base portions 114, 122 respectively and also keep the handle portion stable and
firm. Stops 155a-155d help to restrict the movement of the rollers. Protrusions 157a-157d
are preferably next to the stops 155a-155d. A rib may be between these to add stability.
As handle portion 114 and base portion 112 are essentially hollow, they define a recess
156 into which debris that is picked up by the rollers is stored. In one embodiment,
the handle 114 and base portion 112 are transparent so that the user can easily determined
when the recess 156 is full of debris. In this embodiment, since the top and bottom
portions are permanently connected at, for example, points 151 and/or points 171 a,b
and the rollers are locked into place, the device is then discarded along with the
debris. A new device then must be purchased and used for further cleaning.
[0030] Another embodiment is shown in Figs. 18-24. The device 210 is somewhat similar to
device 110 but it contains additional features. The device 210 has a handle portion
214 and a bottom portion 212 connected preferably by heat formed connector stakes
271a-f that fit into holes. On the top 221 of the handle portion 214 are indicia 223.
The indicia 223 preferably indicate the device's type or brand and may also consist
of a logo as well as the trademark registration symbol 223a. Additional indicia 225a,b
may be located at the front 227 and back 229 of the device 210. The indicia may include
an arrow that indicates to the user that preferred direction of movement for the device.
[0031] In this embodiment, the grooves 215a,b, preferably having textured surface 217 consisting
of small protrusions or indentations, grip points 219 that assist in the gripping
of the device 210. This embodiment may also include ridge 231 around bottom portion
212. The ridge 231 may have a rounded lip to prevent snags. As best shown in Figs.
19-21, this embodiment is more rounded and almost appears to be a semi circle. As
shown, two rollers 260, 261 are located partially within the outer shell of the device
210. The grip points 219 and indicia 223 may be embossed out or in.
[0032] Figs. 22 and 23 show rollers 260, 261 covered with a cleaning fabric 272, 272b. A
somewhat different fastening mechanism for the rollers 260, 261 is also shown. For
example, here spring snaps receive a protrusion on the rollers 260, 261 for easier
assembly. As best shown in Fig. 23, the bottom of the base portion 212 has ramps or
leads 250 to help assemble the rollers 260, 261 into the base 212. The rollers 260,
261 may have protruding axles 251a-251d of differing sizes which interact with the
leads 250a-250d.
[0033] Fig. 24 shows a hanger 261 as an integral part of the handle portion 214. In this
embodiment, a hanger 261 is preferably constructed of plastic and is used to hang
the device 210 from a hook on store display.
[0034] Fig. 25A shows still another embodiment. In this embodiment, device 310 has a very
small ridge 331 and also has a more aggressively sloping front 337 and rear 339.
[0035] Fig. 25B shows the bottom of the device 310 shows scallop cuts 381 in the fabric
372 and the mating bosses 383 on the rollers 360, 361. In other embodiments, these
scallops 384 are not necessary as the fabric would just be cut into rectangles and
folded over both edges of the roller, not just the one.
[0036] As mentioned, various components of the device can be attached by sonic heat staking
or hot melt glue. The heat staking process may have a feature that shows orientation
for future troubleshooting
[0037] The velour cleaning material may be applied to the rollers as a sort of label, that
is, with one side having an adhesive and one side having a unidirectional fabric.
Alternatively, the cleaning fabric may include a properly cut and sized piece of material
hot glued to the roller. The fabric may have semi circular tabs cut out to align with
corresponding structures on the rollers. This makes it easier to fit the fabric to
the roller during assembly. While the cleaning material is typically red velour, blue
and other, lighter colors such as white and yellow may be used. For example, the lighter
colors may be beneficial as they will better show dirt and debris.
[0038] The cleaning fabric preferably has some cushion. The cushion density makes a difference
in exerted force. The velour wears out after time, for example, 6 hours to 8 hours
of use.
[0039] In one embodiment, the roller fasteners may consist of de-nest lugs embedded in the
top housing. In such an embodiment, the roller removal force is about 16 pounds.
[0040] The device is preferably made of transparent 100% recyclable R-PET or some other
suitable plastic resin.
[0041] In another embodiment, the inside of the device is sprayed with glue or some other
adhesive. This feature attracts and holds the debris to the inner walls of the device.
This feature will promote the fact that the device is disposable.
[0042] A process for manufacturing a device assembly that requires a rigid part (e.g., a
roller) to have a dissimilar, in this case a cleaning fabric, material bonded to it
is here described. This process is preferably as follows:
- 1. The cleaning fabric is provided in manufactured rolls;
- 2. A width of fabric is coated on the backside with a heat activated adhesive (e.g."
"hot melt" glue);
- 3. The now adhesive coated fabric is allowed to cool (e.g., a few seconds);
- 4. The cooled adhesive coated fabric is cut to final shape;
- 5. The cut adhesive coated fabric is reheated to activate glue immediately prior to
assembly to the rigid roller part (note that the heat is preferably provided in the
form of radiant, convection, microwave, etc. and/or provided by fabric carrier, or
the rigid part is heated); and
- 6. The rigid part is then presented to the heated, cut, adhesive coated fabric to
produce the roller assembly.
[0043] One advantage of this process is that a machine for manufacturing and assembling
the roller and fabric allows for ease of placement of the fabric onto and over the
edges of the rigid part
[0044] This machine that allows for fabric to be assembled onto a rigid part's surface and
allows for the fabric to be rolled over the edges of the rigid part, all in a single
operation. The machine is well suited to either manual hand assembly or high-speed
automation and has the following attributes:
- 1. Ability to apply adhesive to full roll at high speed, vs. individual pieces
- 2. Ability to apply adhesive at any time, vs. immediately before assembly onto rollers
- 3. Prevents the edges of the fabric from fraying
[0045] The basic operation of the machine is as follows:
- 1. Placing of fabric onto fabric carrier.
- a. The fabric is located on the carrier with the assistance of the "Fabric Stops."
- b. The fabric is supported initially by the "Fabric Springs," although these may be
unnecessary if the fabric is otherwise adequately located directly into the "Part
Cradle."
- c. The fabric has some type of adhesive already applied to it, or else the adhesive
is applied after the fabric is located into the carrier. If a non-adhesive attachment
method is used (i.e. ultrasonic), then the fabric does not have any adhesive on it.
- d. If the fabric is coated with a heat activated adhesive, the heat to activate the
adhesive is applied after the adhesive-coated fabric is placed into this carrier (easier
to handle cold), but directly before the next step. The carrier passes through a conveyor
type heat source, or else the carrier, or roller parts itself is heated.
- 2. Rigid Part (e.g., the roller) is placed onto part holder
- a. This could either be a hand operation or an automated feeder system
- b. Retention of the rigid part in the holder could be accomplished through a number
of means, such as vacuum, sprung retention clips, friction, suction cups, adhesive,
etc.
- 3. The fabric carrier, with the loaded fabric, moves into position under the part
holder
- a. It could also be possible that the fabric carrier is fixed under the part holder
and the fabric is sequentially fed onto it.
- 4. Downward pressure is applied to the "Pusher," compressing the "Holder Springs"
- a. This causes the Part loaded in the Part Holder to press against the fabric, depressing
the Fabric Springs,
and ultimately seating the part against the fabric, formed by the Part Cradle.
- b. Sandwiching the fabric between the part and the Part Cradle causes the ends of
the fabric to raise up from their resting position, key to allowing the Roll-Over
roller to get underneath it.
- c. The Fabric Springs eventually compress below the surface of the Part Cradle, due
to their location in recessed holes.
- d. The pressure could either be provided manually or through automated methods.
- 5. Continued downward pressure on the Pusher compresses the "Pusher Springs"
- a. It is key here that the Pusher springs are harder to compress (higher K value)
than the Holder Springs, so that the Part Holder loaded with the Part is compressed
fully into the fabric and Cradle, and then the Pusher springs begin to compress. This
produces in effect a two-stage action, first compressing the Pusher Springs and then
compressing the Holder Springs.
- 6. As the Pusher springs continue to be compressed, the Roll-Over Roller begins to
contact the Roll-Over Ramp
- a. As the Roll-Over Roller is forced onto the Roll-Over Ramp, the Roll-Over Springs
begin to bend sideways, providing constant pressure between the Roll-Over Roller and
the Roll-Over Ramp.
- b. The constant pressure is important to allow the Roll-Over Roller to get underneath
the fabric to initiate the rollover process
- c. The constant pressure could be provided by any number of means besides the springs,
such as spring wire, spring metal sheet stock, rotational springs, polymer springs,
etc
- d. The Roll-Over Roller may not necessarily need to be a roller. It could perhaps
be a thin fixed part, such as a rigid wire, a wedge shape, etc, anything that could
get underneath the fabric, travel down the ramp, and transfer adequate pressure across
its width
- e. The roll over operation could be on both sides, not just one, by mirroring the
Roll-Over Rollers, Roll-Over Springs, Roll-Over Ramp, and Part Holder Cutout
- 7. The Roll-Over Roller forces the fabric to roll over the edge of the part and seat
against the inside of the part
- a. The cut out in the part holder allows room for the Roll-Over Roller to travel inside
the part
- b. The roll-over action provides the desirable benefit of applying pressure across
the entire application surface of the fabric, including on the edge of the rigid part.
- 8. The pressure on the pusher is now released and the holder springs force the machine
back to its original state.
- a. The part is released from the Part Holder.
- 9. The now combined rigid part with its fabric surface and rolled edges is complete
- a. The Fabric Springs force the assembly back up, out of the Cradle for transport
or removal
