ABSTRACT:
A sewing unit (1) for producing a seam in a sewing-material part (92), in particular for the production of a dart seam in an article of clothing, has a sewing-material holder (45) which receives the sewing-material part (92) between two plate edge parts (54, 55) and moves it via a displacement drive (44) along a sewing machine (2). The sewing-material holder (45) is provided with plate edge parts (54, 55) which frictionally smooth the sewing-material part (92) as it is being fed by a feeding plate (11) into the sewing-material holder (45) which is then placed in its clamping position. This eliminates any need for a further transfer of the sewing-material part 92 to a clamping rail for guiding it along the sewing machine 2. The plate edge parts (54, 55) serve, in the clamped position of the sewing-material part (92), for holding the sewing-material part (92) during the sewing process.
