Abstract
A sewing device ( ) is provided with a programmable electronic control system ( ) for sewing folds and tucks. Such that format-dependent parts (guide tongue, pressure pad) can be eliminated at the time of a change of the seam program the use of a guide tongue is eliminated that depends on the form of the seam and of a format-dependent pressure pad. The feed of the fabric is performed only with a folding tool ( ) with straight folding edge and the holding and guiding of the fabric during the sewing operation using a straight pressure pad ( ). The electronic control system ( ) can be programmed such that the desired seam course is obtained exclusively by the superimposition of longitudinal and transverse movements of the pressure pad ( ). Parameters ( ) that determine the seam course are preferably entered in a graphics-supported manner.
