Abstract
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.
