Abstract:
In a method for unwinding a cake of wound elastomeric yarn by unwinding elastomeric yarn in a creel, passing the elastomeric yarn over a bend in a thread guide and beaming the elastomeric yarn onto a bobbin in a warper head, the improvement which comprisespositioning the bend in the thread guide so as to contact the elastomeric yarn passing over the bend and change the direction of the elastomeric yarn passing through the thread guide, said thread guide changing the direction of the elastomeric yarn no more than one time, attaching the thread guide to a base member so that a portion of the thread guide moves in response to changes in tension in the elastomeric yarn, said base member including means for monitoring the position of the thread guide, monitoring the position of the thread guide so that if the thread guide moves beyond a desired range in response to an increase in tension in the elastomeric yarn, the monitoring means generates an electrical signal.
