A thread guide is slidably disposed in a guide way and in contact with a rotating thread roll having a continuous spiral guide groove. The thread guide has a runner contacting and moving with respect to the guide slot of the roller and an elongated extension arm ending in an upright thread guding device, the extension arm being aligned with the runner of the guide. The length of the extension arm determines the longitudinal acceleration of the thread being wound in the end areas of the spool as the runner passes through the end turnaround portion of the guide slot. The thread is accelerated away from the end of the spool, thus decreasing the possibility of thread buildup or hangover in this region. A double runner device is also provided and includes a positionally adjustable extension arm for the winding of conical spools.
