ABSTRACT:
A method and assembly are for forming a thread reserve when winding a thread onto spool tube in a thread winding apparatus having a spool pin, a pressure roller and reverse thread roller device. The spool tube is carried by the spool pin and rotatably driven by a motor. The spool tube is capable of being swung in a direction toward the pressure roller. The spool tube has a smooth peripheral surface at least in the area of the thread reserve winding. A thread blocking device is disposed at an entry end of the pressure roller and holds back the thread from being introduced to the reverse thread roller device until the thread reserve winding has been wound onto the spool tube. A thread directing mechanism moves an incoming thread back-and-forth over a length of the spool tube defining the breadth of the thread reserve winding being formed. The thread directing mechanism is located ahead of the spool tube when viewing the assembly in the direction of the course of the thread through the thread winding apparatus. The incoming thread is introduced in front of the thread blocking device and into the thread directing mechanism before the pressure roller is in peripheral contact with the spool tube. The incoming thread is wound around the smooth surface of the rotating spool tube while being moved back-and-forth by the thread directing mechanism. The end portion of the thread is then cut to separate it before the pressure roller contacts the spool tube.
