Abstract
The invention relates to a process and a device for the winding-up of textile yarn. The process includes winding-up by double drive, namely peripheral and axial drive, according to which, in a first phase, the torque supplied by the axial drive is decreased progressively to zero, and in a second phase, the rotation of the take-up package is effected by the single peripheral drive. Preferably, the device used is a gas turbine, the inlet pipe to which is progressively obstructed. The invention applies to winding-up of chemical textile yarns.
