ABSTRACT:
The fabric-side hook thread end (GN), which was previously longer than the fabric-side needle thread end (NN) by the amount corresponding to a stitch length, is to be shortened in sewing machines with a thread-cutting device. This object is accomplished by the feed device of the sewing machine, of which there is at least one, performing a partial feed step in the reverse feed direction during the performance of the thread-cutting process.
