Abstract

The present invention is a device (10) for use in cleaning a fabric surface (16) of dust, dirt, pet hair and other debris (20) present on the surface (16). The device (10) includes a pair of cleaning members or rollers (60, 61) disposed on an underside of the device (10) which can roll with respect to the device (10) and with respect to one another. The rollers (60, 61) are selectively contacted with one another such that each roller (60, 61) can assist in removing debris (20) picked up by the opposite roller (60, 61) and dispensing the debris (20) into a collection chamber (32) releasably positioned within a housing (11). The removal of the debris (20) from each roller (60, 61) is also facilitated by opposed edges of a central opening (58) in the housing (11) that contact the rollers (60, 61) and direct the debris (20) into the debris collection chamber (32).

Description

WO 2006/130216 PCT/US2006/012101 -1 FABRIC SWEEPER CROSS-REFERENCE TO RELATED APPLICATIONS This application claims a benefit of priority on patent application no. 11/141,099, filed May 31, 2005, and patent application 29/239,706, filed October 3, 2005. BACKGROUND OF THE INVENTION 1. Field of the Invention 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 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. 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 2 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 5 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. 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 1o 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 15 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. Therefore, it is desirable to develop a lightweight, manually operable fabric 20 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 25 collection chamber. Object of the Invention It is an object of the present invention to substantially overcome or at least ameliorate one or more of the disadvantages of the prior art, or to at least provide a useful alternative.

3 Summary of the Invention There is firstly disclosed herein a fabric cleaning device comprising: a) a housing having a lower end and an upper end defining a recess therebetween, the upper end including a central opening in connection with the recess and s at least one debris removing surface located adjacent the central opening; b) a first cleaning member movably secured within the recess to extend at least partially out of the housing and engageable with the at least one debris removing surface, wherein the first cleaning member is semi-cylindrically shaped; c) a debris collection chamber located in communication with the central 10 opening; and d) an outer shell connected to and disposed around the housing and the collection chamber, wherein the outer shell includes an aperture generally opposite the housing within which the collection chamber is releasably positioned. There is further disclosed herein a fabric cleaning device comprising: is a) 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; b) a first cleaning member movably secured to the housing within the recess; 20 c) a second cleaning member movably secured to the housing within the recess and selectively engageable with the first cleaning member; d) a debris collection chamber connected to the housing and spaced from the recess; wherein the first cleaning member and the second cleaning member have a semi 25 cylindrical shape; wherein each member is rotatable within the recess between a first position where an inner side is rotated into contact with an annular shoulder formed on the upper portion of the inner housing adjacent a central opening in the upper portion, and a second position where an outer side of each member is rotated into contact with the upper portion 30 adjacent the corresponding side support.

3a 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 s 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 io result of the contact of the material on each cleaning member with the housing. According to another aspect of the present invention, the housing preferably 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 15 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. According to still another aspect of the present invention, the housing within 20 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.

WO 2006/130216 PCT/US2006/012101 -6 DETAILED DESCRIPTION OF THE INVENTION 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. 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. 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 forn the closed end 36, and down over the opposed side wall 42. In this WO 2006/130216 PCT/US2006/012101 -7 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. 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. 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. While the preferred embodiment discloses cleaning members 60, 61 that are generally semi-cylindrical in shape, other suitable shapes for the members 60, 61 are also contemplated. 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. 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 WO 2006/130216 PCT/US2006/012101 -8 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. 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. 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. 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 WO 2006/130216 PCT/US2006/012101 -9 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. 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 fonned 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. 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 WO 2006/130216 PCT/US2006/012101 -10 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. 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. Fig. 10 shows an alternative device 110. The device 110 has a housing 11 Oa 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, 1 15b 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 preferably 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. 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.

WO 2006/130216 PCT/US2006/012101 -11 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 171a,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. 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. 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.

WO 2006/130216 PCT/US2006/012101 -12 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 251 a-25 1 d of differing sizes which interact with the leads 250a-250d. 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. 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. 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. Figs. 26-29 show yet another embodiment. This embodiment of device 410 has a single main roller 460 mounted in a semi circular housing 420. The main roller 460 attracts and picks up hair, while internally two small sections of directional material 473 attached to the housing 420 shed the hair from the main roller 460. This leaves the hair trapped inside the housing. The main roller 460 only rotates about 90 degrees in both directions. A stop locks the main roller 460 at a specific point to pick up hair, then when rolled in the reverse direction the roller 460 will almost roll 180 degrees which brings the hair up into the housing 420. The roller 460 locks again. The motion is repeated until the housing 420 is full. The process picks up hair because the directional material is opposing one another. The velour 473 attached to the housing 420 "lays" down while the velour 472 on the large roller 460 brings in hair. When the device 410 reverses direction, the hair on the large roller 460 will pass the same small strip of velour 473 but now the velour 473 on the large roller 460 will "lay" down and the smaller strip of velour 473 traps the hair inside the housing 420.

WO 2006/130216 PCT/US2006/012101 -13 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 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. 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. 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. The device is preferably made of transparent 100% recyclable R-PET or some other suitable plastic resin. 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. The invention may further includes 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. 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 WO 2006/130216 PCT/US2006/012101 -14 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. 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 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 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.

WO 2006/130216 PCT/US2006/012101 -15 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.

WO 2006/130216 PCT/US2006/012101 -16 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 WO 2006/130216 PCT/US2006/012101 -17 a. The Fabric Springs force the assembly back up, out of the Cradle for transport or removal In the preferred embodiment described herein, the rollers fit into the device only one way. Further, although a two roller and single roller version are shown, 3 or more smaller rollers may used. The device may also have dust pan feature for catching and hold the debris within the housing. Various other features, embodiments and advantages of the present invention are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter regarded as the invention.
