Abstract
Techniques produce a crimped composite thread, in which multiple individual threads are extruded in each case in the form of a plurality of strand-shaped filaments, cooled, drawn by means of a drawing device and together crimped by means of a crimping device to form the composite thread. Before the multifilament individual threads are crimped, they are entangled separately in each case by means of an entangling unit of an entangling device. A position and/or orientation of at least one of the entangling units relative to the drawing device, the crimping device and/or a further one of the entangling units is changed during the production of the crimped composite thread.
