ABSTRACT:
An automatic industrial sewing machine which increases productivity and improves quality in the sewing of linings to facing material in the manufacture of jackets. The machine automatically inserts a plurality of different rates of fullnesses at predetermined locations in the seam between the lining and the facing, for a preset number of stitches for each fullness. It also provides positive feeding for piping sewn into the seam which eliminates stretching or bunching of the piping. Finally, the material is held in position after release of the drag clamp by the use of a jet stream of air impinging on the material. The operation of the machine is automatic in that the operator need only place the facing and lining into the drag clamp and into the air guide and depress a switch. The machine then automatically sews the seam with or without piping, inserting the fullnesses desired in the seam, automatically cutting the piping prior to, and at the end of, the sewing of the seam, and automatically transporting the material to a stacker.
