ABSTRACT:
An apparatus and method for the production of a multicomponent yarn which is composed of several multifilament strands with differing characteristics, such as color. The individual strands are drawn in parallel and simultaneously by a pair of godets following spinning, and then crimped by compression in an air jet crimping device. According to the invention, the individual strands are spread apart from one another prior to run-off from the drawing godet in such a way that the distance in the axial direction between the run-off points of the individual strands on the godet surface is increased. This spreading of the strands assures that the strands do not intermix prior to entering the air jet crimping device.
