Sewing machine

摘要

A first carrier unit clamps two pieces of sewing material in a position relative for sewing and relocates them at a rate of carrying speed from a preparation station to a sewing station while relocating them at a rate of sewing speed during a sewing process. A second carrier unit (18) relocates with at a further rate of carrying speed the two pieces of sewing material from the sewing station to a station for deposit. A carrier subunit (16b) is relocated for the first carrier unit so as to ensure a relative sewing position during relocation of the two pieces of sewing material.
