  • 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.
