  • Patent number: 5123367
    Abstract: An automatic apparatus and method for forming a V-top shirt pocket or similar article with a folded region, sewing a stitch to hold the fold, and stacking a plurality of same with distributed hem build-up. An unfolded ply of material is provided to a folding station, which forms a tucked edge fold in the material. The ply is then held at the tucked edge, and the opposite end is folded over a folding rod with an air jet. Holding fingers descend to hold the fold in the ply. A transport carriage arrives at the folding station to retrieve the folded, edge-tucked ply. The transport carriage includes a clamp, which clamps on the folded, edge-tucked ply to hold the fold and edge tuck as the folding station elements retract. The transport carriage carries the folded, edge-tucked held ply through a sewing station in synchronization with a sewing machine, where a V-shaped hem is sewn.

  • Patent number: 4588120
    Abstract: Apparatus and method for cutting a continuous length of strip-like material into elongate strips and forming the strips into fastened loops such as belt loops and the like, including drawing means for drawing an amount of material from a supply, a cutter for cutting the drawn material into a strip of a predetermined length, grasping fingers for grasping the strip at the cutter and for transferring the strip to a forming area, a forming trough, mandrel and folding fingers which forms the strip into a loop, and a stapler for stapling the strip into a fastened loop. The operations of drawing the material from the supply and cutting the material into strips occur simultaneously with the steps of forming and stapling a previously-cut strip, so that high speeds of operation are possible.

  • Patent number: 4478359
    Abstract: As a strip of material is intermittently moved along its length from a reel, it is heated so as to remove its curl, it is cut into segments in the form of collar stays, and adhesive is applied to one surface of the collar stay segments. The individual collar stays are then moved laterally into alignment with spaced collar template elements, and then moved into overlying relationship with the pointed portions of the collar template elements, and a worker manually inserts a partially completed collar structure about the template elements. The worker presses the collar material against the adhesive on the collar stay and lifts both the collar and the collar stays from the templates, with the adhesive carrying the collar stays with the collar material. The collar stays are subsequently sewn into the collar with top stitching about the edge of the collar structure.

  • Patent number: 4356744
    Abstract: Dome-shaped shoulder pad discs are placed in face-to-face overlying relationship and loaded in segmented carriers of a surface conveyor system. Each carrier moves its shoulder pad discs to a first station where the material is cut between the segments of the carrier and formed into a leading stack of shoulder pads, a following stack of shoulder pads, and an intermediate stack of waste material. The carrier is moved to a second station where the intermediate stack of waste material is pushed downwardly between the segments of the carrier and ejected. The leading segment of the carrier is moved to a third station where the leading stack of shoulder pads is picked from the leading segment of the carrier and moved to a stacker, and then the following segment of the carrier is moved to the third station where its stack of shoulder pads is picked from the following segment of the carrier and moved to the stacker. The stacker forms the shoulder pads in a vertical stack.

  • Patent number: 4227470
    Abstract: A placket forming system comprises a double needle sewing machine with a cutter which cuts between the lines of stitching and a positioning apparatus including mechanically movable arms with gripping surfaces which operate in conjunction with the sewing machine and cutter apparatus. The positioning apparatus grips a work piece such as a shirt front placket assembly at the sewing machine work surface after the work piece has been sewn and cut and moves the work piece a predetermined distance along the work surface to a proper position under a cutting blade, and the cutting blade is actuated to make a crow's foot cut in the work piece at the end of the line of stitching in the work piece.
