  • Patent number: 6823763
    Abstract: A fabric cutting system for cutting a pre-selected pattern from a fabric stock and transferring the cut fabric piece to a workstation. The system includes a cutter assembly for cutting the preselected pattern from the fabric stock. A configurable pickup assembly is located between the cutter assembly and the workstation and adapted to pick-up and transfer the cut fabric piece to the workstation. A hold down table adjacent to the cutter assembly maintains the position of the fabric stock in a determinable relationship to the position of the cutter assembly and the configurable pickup assembly. In the preferred embodiment, the hold down table is vacuum operated and includes a moving mesh belt on which and the fabric stock is moved downstream towards the pickup assembly as the fabric piece is being cut by the cutter assembly. This arrangement results in substantially higher throughput through the fabric cutting system.

  • Patent number: 6462820
    Abstract: A moving fabric web vision inspection system. The apparatus includes at least two electronic cameras on one side of the moving fabric web for measuring the light intensity of a predetermined area of the moving fabric web. A high frequency, backlight, contrast panel on the other side of the moving fabric web provides reference point for the cameras to detect a defect. A controller connected to each of the electronic cameras generates a stop signal if the light intensity of the predetermined area of the moving fabric web deviates from a predetermined value. The predetermined value corresponds to a detected defect in the moving fabric web. Finally, a repair station downstream from the cameras allows an operator to repair a defect detected by the vision inspection system.

  • Patent number: 5867878
    Abstract: A fabric width control system for a fabric compactor for compacting a moving fabric web. The system includes a vision assembly for measuring the width of the moving fabric web downstream of the fabric compactor. A mechanical spreader is located upstream of the fabric compactor for adjusting the width of the web in response to a control signal from an open loop controller. The controller is connected to the vision assembly and the mechanical spreader for controlling the position of the mechanical spreader in response to a change in the width of the moving fabric web from a pre-set value. In the preferred embodiment, a cloth stabilizer is located downstream of the fabric compactor for maintaining the moving fabric web at a pre-determined position with respect to the vision assembly, thereby further increasing the accuracy of the system.

  • Patent number: 5697762
    Abstract: A garment stacker for stacking garments in a garment stack. The apparatus includes a stacking tray having a support tray for supporting garments placed thereon in a garment stack and a tray actuator for adjusting the position of the support tray. A rotary stacker is positioned adjacent the stacking tray, wherein the rotary stacker repeatedly moves between a loading and an unloading position to successively stack garments on the stacking tray in a garment stack. A controller directs the tray actuator to position the support tray upwards when the rotary stacker is in the unloading position so as to press the garment stack between the stacking tray and rotary stacker. An unloader moves the garment stack from the stacking tray after a garment stack has been formed thereon.

  • Patent number: 5664512
    Abstract: An apparatus for receiving a garment piece at a first workstation and moving the garment piece to a second workstation where the garment piece is seamed together. The apparatus includes a garment piece transfer system located adjacent to the first workstation for engaging the garment piece at the first workstation and for moving the garment piece to the second workstation. A vision and control system is located adjacent to the first workstation for determining the position of the garment piece at the first workstation and sending a control signal to the garment piece transfer system to engage the garment piece at the first workstation and move the garment piece to the second workstation. A sewing machine is located at the second workstation for seaming the garment piece together. The vision and control system also determines a parameter value for a selected parameter of the garment and places the garment into a reject or a non-reject class based on a comparison of the parameter value and a reference value.

  • Patent number: 5381937
    Abstract: A pocket-folding device for folding a pocket blank and securing the folded pocket to a pocket-carrying article, the device having a locating fixture supported by a frame to receive the unfolded pocket blank, a top die and movable bottom die supported by the frame, and a vacuum hand associated with the frame selectively moving to pick up the unfolded pocket blank from the locating fixture and carry it and release it over the pocket form to form side and bottom-draped edges. The pocket form and pocket blank move up to mate with the top die. The bottom die then moves up to mate with the top die to form a die cavity around the pocket form and pocket blank while selectively directed air flows into the top die and folds the draped pocket edges around the pocket form. Heat is applied to the folded pocket edges to set pocket edge creases therein, and the pocket form, pocket and bottom die move downwardly to the original bottom die position with the pocket-folded edges held between the pocket form and the bottom die.

  • Patent number: 4044438
    Abstract: Lengths of yarn are bound together in the center to provide relatively short yarn bundles for use in forming yarn balls of the type usually referred to as "poms." A forming wheel is supported for rotation and includes equally spaced forming stations about the periphery for receiving yarns and arranging them into a generally parallel, composite arrangement. The wheel is indexed in a step-by-step manner a distance equal to the distance between successive forming stations and the composite arrangement of yarns is gripped and confined at each of the spaced forming stations. Binder elements are sequentially applied around the bundle of yarns as the successive forming stations move into alignment with a binder applying head. The bound yarns are then cut between successive forming stations to provide lengths of yarn bound together in the center and held in each forming station. The cut and bound together bundles of yarn are then successively stripped from the forming wheel and removed from the machine.
