ABSTRACT:
Flypieces are fed by a conveyor to a sewing station in a sewing machine which is operated by a sensor mounted a spaced distance in front of the sewing station to sew the flypieces to a slide fastener chain. The linear rate of feed of the flypieces by the conveyor is slower than the linear rate of feed of the flypiece and slide fastener chain through the sewing station by the sewing machine, and operation and termination of the sewing machine in response to the sensor is delayed so that uniform spacing is produced between flypieces sewn on the slide fastener chain.
