  • Patent number: 6155186
    Abstract: An apparatus and method for automatically stitching a material portion by moving the material portion over a sewing table relative to a sewing head. In particular, the present invention includes a structure, device, or other mechanism for reducing friction between the material portion and the sewing table, whereby the material portion is more easily movable over the sewing table. The present invention especially relates to the manufacture of mats having a non-skid backing which would otherwise be very difficult to move relative to a sewing head for sewing the mats.

  • Patent number: 6113716
    Abstract: An automated apparatus and method for sealing an edge region of a planar material ply includes a central controller and at least one platform. The automated apparatus and method further employs a mechanism for picking a single planar material ply in addition to a mechanism for moving the single planar material ply to the platform. The automated apparatus and method includes a sealing device which seals the edge region of the planar material ply where the sealing device provides a fluid to a predetermined focused region within the edge region. The fluid substantially shrinks and melts strands in the focused region of the planar material ply.

  • Patent number: 5806449
    Abstract: A highly efficient, simplified method and apparatus for joining knitted shirt sleeves to shoulder openings of knitted shirt bodies. A knitted sleeve section, oriented outside-out, is engaged by a limited shoulder edge margin only by guide rollers, which can be separated to apply a very limited, controlled circumferential tension to the mounted sleeve section. A knitted shirt body, oriented inside-out, is positioned with a shoulder edge margin directly surrounding the shoulder edge margin of the sleeve section, and also maintained under light tension. A retractable support is positioned underneath the free portion of the sleeve section during loading of the shirt body. The two fabric sections are arranged to be controllably advanced in unison by the guide rollers on which they are supported while a sewing operation is performed.

  • Patent number: 5555833
    Abstract: An apparatus for high production assembly and sewing of tubular sleeve sections to shirt bodies. Tubular sleeve sections are loaded onto sleeve cones, preferably of cylindrical or frusto-conical form. The sleeve cones may be mounted for pivoting movement to facilitate manual loading. A retractable hollow body shell closes over the loaded sleeve cones, and a shirt body is loaded over the body shell and previously loaded sleeve sections. Load fixtures, comprising a body shell and a pair of sleeve cones, are mounted on a carrier, preferably a rotary turret, for advancement from one work station to another, for loading, sewing and unloading operations. For sewing, the load fixtures are bodily detachable from the carrier, and rotated about the axis of the sleeve cones, while the shoulder seams are sewn by a stationary sewing apparatus. Shirt bodies are loaded with an inside-out orientation for the sewing operation.

  • Patent number: 5505149
    Abstract: A method and apparatus for sewing sleeve sections to a knitted shirt body. The sleeve sections are provided with a right-side-out orientation and are engaged and supported for sewing by a limited edge margin. A shirt body, supplied in an inside-out orientation, is applied over a previously loaded sleeve section, and is also engaged by only a limited edge margin at the sleeve opening, with the shoulder margin of the shirt body closely surrounding and approximately aligned with the edge margin of the sleeve section. The two components are placed under limited tension to equalize the respective circumference dimensions and are controllably advanced while a shoulder seam is sewn. The respective edges are guided and aligned as they approach the sewing position. A pair of opposed fixtures and sewing heads are provided at each sewing station, so that both sleeve sections and both sides of the shirt body can be loaded in preparation for sewing.

  • Patent number: 5406900
    Abstract: A method and apparatus are disclosed for automating the sewing of tubular sleeve sections onto tubular shirt bodies, as in the manufacture of T-shirts. Shirt bodies and sleeve sections are applied over a generally cylindrical body form having portions aligned with the sleeve openings of the shirt body. In one version, the sleeve sections are applied inside-out and inner end first over opposed hollow sleeve cones. The areas of the shirt body surrounding the sleeve openings are engaged at spaced points by positioning devices, which independently position segments of the sleeve opening edges with respect to predetermined reference planes. Thereafter, tubular sleeve sections are applied axially over the body form, in surrounding relation to the shoulder areas of the shirt body. As segments of the sleeve inner edges approach the reference planes, individual segments are engaged and retained in position, until all portions of the sleeve edges are aligned with their respective reference plane.

  • Patent number: 5365867
    Abstract: There is disclosed a computerized control system for stitching apparel parts in various stitching patterns according to individual designs or styles. The control system prevents mismatching the hardware components used to hold the apparel parts during stitching thereof and a selected computerized program which controls an individual stitching pattern. A program may not be selected unless a code identifying such program is found to match the code which identifies the hardware used for a particular style or design.

  • Patent number: 5349913
    Abstract: A method and apparatus are disclosed for automating the sewing of tubular sleeve sections onto tubular shirt bodies, as in the manufacture of T-shirts. Shirt bodies are applied over a generally cylindrical body form having portions aligned with the sleeve openings of the shirt body. The sleeve sections are applied inside-out and inner end first over opposed hollow sleeve cones. The body form, oriented horizontally for loading, is indexed to a sleeve inserting station, where it is re-oriented vertically. The areas of the shirt body surrounding the sleeve openings are engaged a spaced points by positioning devices, which independently position segments of the sleeve opening edges with respect to predetermined reference planes. Thereafter, tubular sleeve sections are applied axially over the body form, in surrounding relation to the shoulder areas of the shirt body.

  • Patent number: 5255621
    Abstract: A method and apparatus is disclosed for low cost, high production setting of pockets on tubular shirt bodies. An indexable turret apparatus is provided forming a plurality of radially extending work platforms arranged successively to receive and support loosely draped tubular shirt bodies and to support and position pocket plies thereover. At successive index positions, the pocket plies are folded and clamped on the front of the shirt bodies, then sewn to the shirts in the desired manner, and then removed and draped over a stacking bar, for eventual further processing. A single operator, working at the load station, places the shirt bodies and pocket parts in position, after which successive indexings of the equipment cause the necessary production operations to take place.

  • Patent number: 5029537
    Abstract: Method and apparatus is disclosed for the automated forming and hemming of pocket plies or like parts provided with a contoured top flap. Individual pocket plies are picked from a stack and positioned on a plate provided with V-contoured forward end edge. A clamping die clamps the ply to the plate and conforms a projecting hem-forming margin to the V-contoured (or other shaped) forward edge. A transfer mechanism completes the hem fold and, by the use of a transfer clamp, engages the folded hem area. After the clamping die is opened, the transfer clamp removes the ply and conveys it to a sewing station, while forming the top fold of the pocket ply. The top fold is completed as the transfer mechanism places the ply on the surface of the sewing table and transfers it to the control of a controllably movable sewing clamp.
