Abstract
A method and apparatus for delivering thread from a coiled thread supply to a thread user, is arranged and constructed to avoid twisting, snagging, and breaking of the thread, especially threads of the so-called "Lurex".RTM. type. For this purpose the supply spool is positively driven in response to a drive control which drives the spool in a direction of the original winding of the thread onto the spool, that is, opposite to the direction of the unwinding of the thread from the spool so that the take-off point where the thread separates from the winding on the spool, remains approximately stationary or even completely stationary due to the compensation of the tendency of the take-off point to travel in a direction opposite to the original winding direction. The take-off point remains able to travel axially back and forth along the spool.
