ABSTRACT:
A method and sewing apparatus including a twin-needle sewing machine (3) for making a pocket insert having a flap. The workpiece (47) is placed in a preparation station (50) and gripped by clamping plates (41, 42), then transported into a sewing position (51), and thereafter into a cutting position (52). Before the seams are made, measurement variables which provide information with respect to the angles formed by the flap-limiting edges are fed to a control (23). As a function of the measurement variables, a control (23) automatically sets the angles of the corner knives (69, 70) provided at the cutting position (51).
