  • Patent number: 4787325
    Abstract: An automatic and operator-unattended apparatus and method for forming a stitched coin pocket in a ply of material. A continuous length of material is provided to a folding station, which imparts a generally Z-shaped fold in the material by moving parallel plates along paths substantially parallel to each other, while the material is held by holding plates. A carriage with gripping fingers holds the fold in place while moving the length of material out to a predetermined length. A cutter cuts the material into a predetermined length. The carriage then pulls the ply of material through a sewing station where the fold is stitched. The carriage then places the sewn folded ply atop a stack of similarly formed articles by positively depositing same on the top of the stack. An improved stacking apparatus presents a substantially flat stacking surface for the article by allowing tilting of the stacking table to compensate for the increased thickness at one end of the ply due to the presence of the folded region.

  • 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: 4324087
    Abstract: Tubular bag material is threaded downwardly between spaced support members. A garment support assembly is inserted into the tubular bag material at a level below the support members and then moved upwardly between the support members and rests on the support members. A garment is hung from the hook at the lower end of a downwardly projecting support rod extending from the garment support assembly and the tubular bag material is pulled downwardly by an operator about the garment. A bag cutting and sealing means moves into contact with the tubular bag material about the support rod to form the upper end of the bag about the garment and to cut the formed bag away from the tubular bag material. The operator then pulls the formed bag away from the tubular bag material down onto the garment.

  • 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.

  • Patent number: 4176566
    Abstract: Sheet material is moved along its length from a supply to a take-up spool and the material is inspected as it is moved. A garment pattern image is projected on and is moved with the material. The operator determines where the material is to be cut either from the length accumulated on the take-up spool or from the image projected on the material, and if a flaw in the material is detected, the operator determines if the flaw should be removed by identifying the pattern part in the garment from the image projected on the material where the flaw will appear. If the flaw is to be removed, the operator cuts the flaw out and splices the cut ends of material together at splice marks in the image projected on the material. The spools loaded with sheet material with this procedure are loaded in a creel, and the ends of the sheets of material from the spools in the creel are aligned in a vertically stacked arrangement and moved to a cutting apparatus where the garment pattern is cut in the stacked sheets of material.

  • Patent number: 4112860
    Abstract: A series of shirt cuff pattern parts are placed in spaced apart relationship on a web of lining material and a conveyor belt system engages and holds the layers of material together as they are moved through a folder and a sewing machine. The movement terminates automatically if the space between the pattern part last received by the system and the pattern part next to be fed to the system is too great or too small. The connected together series of partially completed shirt cuffs is continuously accumulated from the sewing machine on a reel, and the reel is subsequently moved to another work station where the connected series of partially completed shirt cuffs is fed to a cutter on a demand basis. The web of lining material is cut adjacent the trailing edge of the leading pattern part, and when an operator removes the separated partially completed shirt cuff from the connected series for further processing, the feeding and cutting steps are repeated.

  • Patent number: 4004477
    Abstract: Fabric cutting apparatus for accurately cutting over-cut pattern pieces, including a pair of band knives spaced apart a distance equal to the width of the pattern pieces, and a plurality of clamp members which hold a stack of the over-cut pattern pieces while a continuous conveying means carries the clamp members between the band knives for cutting.

  • Patent number: 3979876
    Abstract: A carton sealer system moves a plurality of boxes with telescoping upper and lower sections along a horizontal conveyor path, and the top sections are lifted to expose the side walls of the bottom section. Adhesive is applied to the exposed side walls of the bottom sections, the top sections are urged downwardly to their fully closed positions, and the top wall of the top section is urged downwardly and the side walls are pressed inwardly to expel the air from the box and to seal the sections of the box together.

  • Patent number: 3970021
    Abstract: A series of shirt cuff pattern parts are placed in overlying relationship on a web of lining material and a conveyor belt engages the upper surfaces of the web of lining material and the pattern parts and holds the layers of material together as they are moved through a sewing machine. The overlying side edge of each of the pattern parts is folded down under an edge of the web of lining material, and the sewing machine sews through the folds. A predetermined range of lengths of the connected together series of partially completed shirt cuffs is continuously accumulated from the sewing machine, and are continually fed from the accumulation to a cutter, and are separated by cutting the web of lining material adjacent the trailing edge of a pattern part so that each partially completed shirt cuff is formed with a short length of the web of lining material protruding from the shirt cuff panel pattern part, and the pattern parts are stacked.
