ABSTRACT:
In a process of producing hemstitches by means of a zigzag sewing machine, in which straight stitches spaced from the edges of the fabrics to be sewn are formed, first zigzag stitches of a predetermined width are formed which extend between the edge of the fabrics and the straight stitches at a predetermined distance corresponding to the predetermined width of the zigzag stitches and secondly, zigzag stitches are formed which extend between the first zigzag stitches and the straight stitches. The second zigzag stitches formed are wider than the first zigzag stitches.
