Abstract

Friction crimping of synthetic threads with the aid of rotating discs characterized by the employment of the thread to be crimped for driving the discs. There may be a simultaneous crimping of two threads with twists of the same or of opposite hand, of which only one thread serves to drive the discs. Apparatus for carrying out the method of friction crimping is also provided.
