A slide fastener is sewn to a pair of fabric pieces in a sewing station defined by a double-needle sewing machine. A pair of fastener stringers is twisted around in mirror symmetry with respect to the longitudinal centerline of the slide fastener. A slider, which is slidable on and along the fastener stringers, is temporarily held by a slider holder disposed upstream of and adjacent to the sewing station. As the sewing operation progresses and until after the engagement of the slider with the bottom end portion of the slide fastener, the pair of fastener stringers are automatically progressively uncoupled. The further movement of the slide fastener causes the slider to be forced by the bottom end portion of the slide fastener past the slider holder.
