Abstract
The present invention introduces a yarn y that is unwound from a supply bobbin,into a control member,for controlling the propagation of twisting toward a supply bobbin, then introduces the yarn into a friction-disk-type false twister,to suppress fluff, and finally controls the yarn feeding speed in the friction-disk-type false twister in order to control the yarn tension. The present invention can reduce the amount of fluff on a yarn that is unwound from a supply bobbin and wound around a winding package and control the yarn tension. Therefore, the present invention eliminates the needs for a special device for controlling the tension.
