摘要： A method and a device for producing a pocket on a workpiece in which a pocket cut is folded at a margin of two lateral portions and one bottom portion connecting the lateral portions and attached by a stitch row to a workpiece. According to the invention, the folded pocket cut is additionally formed with folds situated in the lateral portions so as to manufacture extensible and spacious bellow-typed pockets. The device for producing such extensible pockets on workpieces is equipped with a workpiece folding device for folding the pocket according to the method described, a sewing machine and a control system for controlling a relative motion between the needle of the sewing machine and the workpiece and the folded pocket cut, so as to automatically perform a fastening stitch row according to a predetermined contour for attaching the folded pocket cut onto the workpiece.
