ABSTRACT:
In a sewing station, a preceding cloth piece is sewn to a slide fastener chain from a leading end of the preceding cloth piece to a predetermined position short of a trailing end thereof, and the sewing is terminated when it reaches the predetermined position. On the other hand, in a cloth-piece supply station, a succeeding cloth piece is fed at a high speed toward the sewing station to an upstream position spaced a predetermined distance from the trailing end of the preceding cloth piece while being stopped, whereupon the sewing is started when the leading end of the succeeding cloth piece contacts with or nearly contacts with the trailing end of the preceding cloth piece. As a result, the remaining portion of the preceding cloth piece is sewn. These driving timing is sequentially controlled via a control unit based on various detection signals from a plurality of cloth-piece detectors.
