ABSTRACT:
A textured yarn is directed through a path in which the textured yarn plug forms a loop in which the direction of the yarn plug is changed and the speed of the yarn plug is increased via a draw-off bobbin. The yarn plug within the loop is loosened and the resulting yarn is stretched to form a yarn which can be wound up. The deflection loop in which the yarn plug is loosened is stable depending upon an appropriate choice of speeds between the speed at which the plug is guided into the loop and the speed at which the yarn is drawn from the loop. The deflection loop need not be supported by any mechanical devices.
