ABSTRACT:
A yarn package holder on a creel, with a mechanism for rapidly stopping the yarn package holder once yarn is no longer being drawn. The mechanism has a pivoted member, one end of which carries a transverse braking control arm that overlies the yarn, and the other end of which is secured to an end of a tensioning cord wrapped at least once around a pulley on the yarn package holder. When yarn is being drawn, the braking control arm is lifted, which has the effect the loosening the cord around the pulley so that the braking effect is small. When yarn is no longer drawn, the braking control arm drops, which has the effect of tightening the cord around the pulley and rapidly stopping the yarn package holder.
