Abstract
The invention is concerned with a sewing apparatus having a sewing machine mounted on a work table, fabric workpiece clamping means capable of holding and releasing the fabric workpiece on the work table, and a feed driving mechanism for intermittently feeding the fabric workpiece clamping means, whereby machine sewing and fabric workpiece feed are repeated alternatingly thereby sewing buttons or forming buttonhole stitches to a plurality of sewing portions on the fabric workpiece. The sewing apparatus has auxiliary fabric workpiece clamping means operable independently of the fabric workpiece clamping means. In the case of processing of a long fabric workpiece, when the required amount of feed of the fabric workpiece exceeds the allowed stroke of the fabric workpiece clamping means between the feed start position and the maximum feed position, control means operate to allow the fabric workpiece clamping means to release the fabric work piece after the fabric workpiece is retained by the auxiliary fabric workpiece clamping means and to return towards the feed start position where the fabric workpiece clamping means again retain the fabric workpiece.
