Abstract (en)
A microprocessor-controlled machine and method for automatically removing adjacent pieces from a stack (380) of fabric plies (381) (382), properly orienting these pieces adjacent one another, and joining these pieces by sewing at least one stitch or seam, to form a partially sewn garment such as a T-shirt sewn at the shoulder seams. The machine includes fabric positioning and engaging mechanisms, and a transport means for engaging and conveying fabric pieces while maintaining engaged portions thereof in predetermined alignment. The over-all machine includes three portions: a positioning portion (32) having a plurality of movable platforms (76) (145) (160) and a traveling carriage (130) equipped with a powered roller (332) that carries a fabric engaging mechanism (348); a sewing portion (34) having a sewing machine, (210) a plurality of platforms and a fabric transport mechanism that includes a pin chain (206) for automatically engaging and transporting fabric past the sewing machine while maintaining the engaged fabric in proper alignment; and an unload/stacker portion (36) for disengaging the partially sewn garment from the pin chain and automatically stacking same.
