ABSTRACT:
In the stuffing of synthetic continuous filamentary threads in stuffer boxes, special value is to be placed on the thermal treatment and especially the cooling of the initially crimped filaments. The filaments in the configuration of a compact thread plug, which is formed in the stuffer box, can be wound on a rotatably driven drum in several helical windings, the last thread plug winding can then be disentangled again at the end of the drum, and the finished texturized thread drawn off. The disentangling of the thread plug and the drawing off of the thread is improved by the present invention through an application of axial and/or radial forces or pressures onto the last thread plug winding in the region of the disentangling point. Suitable mechanical and pneumatic devices are provided by the invention for this purpose.
