ABSTRACT:
The machine includes a fixed guide that defines two longitudinal work tops, first and second work tops, which support and guide the edges of leather articles to be sewn together. A curved needle, located next to the first work top, pierce the edge located on the first work top, pass through a slot in a guide, pierce the another edge, which is being pressed onto the second work top by a pressure foot, and, finally, operates in combination with a crochet hook to produce a stitch. The needle-pressure foot assembly serves to intermittently feed the two edges while a feed dog, acting in combination with a second pressure foot located downstream of the assembly, crimps the edge situated on the first work top.
