METHOD FOR REMOVING A YARN WRAPPED AROUND A BUFFER AND FOR WINDING THE YARN INTO A PACKAGE,AND APPARATUS FOR APPLYING THIS METHOD

摘要

In a method for removing a yarn (207) wrapped around a buffer (206) and for winding the yarn on a winding spool (209) to form a yarn package a transverse displacement of the yarn is developed to compensate for tension variations. This transverse displacement is imparted to the yarn through being removed from the buffer in a continuously changing position due to differences in the speed at which the yarn is removed from the buffer (206) with respect to the speed at which it is fed to the buffer. The transverse displacement is converted into a control signal by a sensing unit, which control signal is applied to a regulating means to vary the winding speed of the yarn in such a way that said continuously changing position is kept within fixed limits.
