Folding Workpiece Patents (Class 112/475.06)
  • Patent number: 6481362
    Abstract: A panel positioning system can be used to position side panels during manufacture of a pant. As a pant is transported in a machine direction, the panel positioning system moves a pant side panel in a direction generally perpendicular to the machine direction. The panel positioning system can comprise a drive mechanism, a positioning mechanism operatively connected to the drive mechanism, and a head connected to the positioning mechanism. The drive mechanism and the positioning mechanism can cause the head to move in an orbital profile and contact the side panel. The orbital profile can lie in a plane generally perpendicular to a pant transport plane or in a plane oblique to a pant transport plane.

  • Patent number: 6439144
    Abstract: A method of making flower-shaped bath scrubber uses a bar as the support to pierce through a netting band which is folded at one end, then use the bar as an axis to have the remaining netting band run through one end of the bar. Then move the netting band laterally along the bar to another end and have the remaining netting band run through the bar from another end. The foregoing process is repeatedly performed until the netting band is completely disposed on the bar. Then fasten one end of the netting band and remove the bar. The wound around netting band then may be unfolded and stretched to form a shape desired. After another fastening, a flower-shaped netting bath scrubber will be formed.

  • Patent number: 6435116
    Abstract: The present invention provides a continuous process for the manufacture of a garment. A web of fabric including opposing web side edges wherein one of the opposing web side edges is proximate the garment bottom edge of the garment is provided. The web of fabric is cut, thereby forming a fabric web wherein the fabric web includes one of the opposing web side edges opposed to an octagonal shape pattern defining pairs of shoulder side edges having a side edge located between the shoulder side edges of each pair of the shoulder side edges and edges located between the pairs of shoulder side edges. The side edges of the fabric web are cut, thereby forming edges defining neck openings in the fabric web. The fabric web is cut, thereby defining discrete garment-sized pieces wherein each of the discrete garment-sized pieces of the fabric web includes at least one neck opening, a front panel having a pair of opposing garment side edges, a garment end portion, and a bottom edge.

  • Patent number: 6431252
    Abstract: A curtain for a dock shelter that is easily assembled alone and as part of a dock shelter. The curtain includes a sheet that has a pocket mounted thereon. The pocket is adapted to receive a flexible stay and include a slit that inhibits movement of the stay within the pocket. In another aspect, the invention relates to a method of making a curtain. The method includes the steps of securing a pocket to a sheet; forming a slit in the pocket (e.g., by cutting the pocket); inserting a flexible stay into the pocket; and positioning the stay adjacent to the slit. The invention also relates to a method of making a vehicle shelter and mounting the shelter to a loading dock. The method includes the steps of mounting a frame to the loading dock; securing a pocket to a curtain; forming slits in the pocket; inserting a stay in the pocket adjacent to the slit; and placing the curtain against the frame.

  • Patent number: 6412430
    Abstract: Flexible strap is passed around an elongated portion 11 of load-bearing hardware 10, and the two ends 2, 3 of the strap are overlapped, held in a curve, and stitched together. The overlapped strap portion is then centered around the elongated hardware portion and is formed into an eye that retains the elongated hardware portion. The eye is closed by stitching through all four strap layers of the strap extending from both sides of the hardware portion. A confluence wrap 5 is preferably wrapped around the eye closure area before this stitching. Preferably a nylon buffer is placed in the eye between the hardware and strap, and stitched in the eye closure area, to prevent chafing of the strap on the hardware. The curvature sewn into the overlapped strap ends provides even distribution of stress on the two ends when a load is placed on the hardware.

  • Patent number: 6401642
    Abstract: A process for folding or folding over pockets with round edge sections is provided along with a device for carrying out the process. Round folding slides (9; 53), provided with concave folding edges (49; 54), are either moved or designed such that their ends (50, 51; 55), either one after another or simultaneously, lead in relation to the middle area of the concave folding edges (49; 54). An especially intense folding effect is thus exerted on the transition areas between the round and straight pocket edge sections and a pocked folded edge that is uniform on all sides is thus obtained.

  • Patent number: 6293213
    Abstract: A method and apparatus for automatically cutting notches at specific locations on a web which are separated by predetermined lengths which are the outer dimensions of a pillowtop mattress. The web is pulled through a sewing station with a traction drive. Slack is induced in the web downstream of the traction drive. Predetermined lengths are drawn out of the slack bin in a single motion through a linear measuring device. A knife disposed in close proximity to the measuring device cuts the notches at the specific locations and subsequently severs the notched portion from the remainder of the web.

  • Patent number: 6192816
    Abstract: Method and apparatus for forming and joining large and small hems particularly on denim jeans and other types of trousers. An internally folded large hem is formed mechanically and in a highly accurate manner by engaging the end portion of a trouser leg under circumferential tension and folding a projected hem margin into the trouser leg while supporting opposite sides of the trouser leg in a region immediately adjacent to the desired hem fold line. A full depth small hem may be formed by compressing a limited portion of the large hem into a fold, with the raw edge of the fabric positioned substantially at the fold line of the large hem. The configuration of the compressed limited portion is retained until the sewing machine is in position to grip it and commence sewing. A continuous fold former is brought into position before sewing is commenced to complete the small hem folding initiated by the initial compression.
