ABSTRACT:
An adjustable template for use in a sewing device for sewing workpieces of different shapes. The template has a supporting plate and a plurality of segments each having wedge-shaped lateral edges, a bearing surface for a template follower means and a slot-shaped clearance formed in the bearing surface, for receiving and slidably fastening a flexible connection wire. As a result of connecting all segments at their bearing surfaces, only several of the plurality of segments are secured to the supporting plate. Consequently, an alignment of the bearing surfaces of the segments according to a required course of a seam, is simplified.
