ABSTRACT:
A sewing method and apparatus is disclosed for preventing raveling of a cut cloth edge in the making of garments such as slacks and skirts. A pair of sewing machines symmetrically arranged with respect to a cloth feeding line are disposed oppositely to each other. Each sewing machine has an auxiliary guide for contacting the upper surface of a cloth, a cloth edge guide and a cloth stopper. Opposite edges of the cloth are simultaneously and automatically guided along respective sewing lines by the guides and serged by the sewing machines without failure. In operating the pair of sewing machines, another additional sewing machine can be operated to serge other edges of the next cloth.
