ABSTRACT:
To equalize yarn tensions in a normal winding mode and a yarn switching mode when a yarn take-up operation is carried out by a yarn winder, the surface speed of the contact roller 4 or the frequency of current for driving the contact roller-driving motor 7 is controlled in a programmed manner. The programmed control is based on whether the winder is in the normal winding mode, the yarn switching mode in which the yarn is switched from a full bobbin to an empty bobbin, or a soft-touch winding mode in which the contact roller is brought into soft contact with the empty bobbin.
