The loading device may include a detection means to identify an empty receiving bullhorn of the creel assembly, a positioning means to adjust a bullhorn carrying a yarn package to be loaded onto the creel assembly so that the free end of this bullhorn is placed in front of the free end of the empty receiving bullhorn of the creel assembly, and a transfer mechanism for the effecting translation of the yarn package to the empty receiving bullhorn of the creel assembly.
Disclosed is a system for winding an end of a thread on a central axis of a spool. The system includes a support means for the central axis, the support means being associated with a mechanism for driving this axis in axial rotation. The system further may have a mechanism for moving a portion of the thread to be wound, positioned downstream of the free end of the thread, and a hooking interface to catch a portion of the thread to be wound, this interface being positioned at the end of the spool central axis and fixed in rotation with the central axis to drive the winding of the thread around the central axis. Finally, the system may have a cutting mechanism of the thread upstream of the portion of the thread interacting with the hooking interface.

Disclosed is a yarn management device in a yarn treatment line downstream of a crimping box and upstream of a thermofixing means for crimping, said device including a fixed support and at least one axial drum positioned upstream of the thermofixing means. In some cases, the inlet of the crimping box is formed by one or more crimping rollers for feeding at least one yarn into the crimping box. The drum is traversed by a yarn in the crimping box and mounted on the fixed support of the device so as to perform a substantially axial rotation, allowing the generation of at least one false twist on the treated yarns.
