ABSTRACT:
A creel for supplying yarns from a plurality of respective packages to a takeup machine such as a warp winder has a support defining respective supply stations carrying the yarn packages, respective stationary brake elements on the supports at the stations each having a braking surface, respective tension-sensing deflectors at the stations, and guides for directing the yarns from the respective packages over the respective braking surfaces and around the respective deflectors. Respective movable jaws movable toward and away from the respective stationary jaws can be actuated via respective springs to press against the yarns on the respective surfaces with a force capable of varying smoothly and steplessly up to a relatively high nominal level corresponding to high tension in the respective yarn. A sensor connected to the deflector responds when the tension in the yarn at the deflector drops below a predetermined low tension, typically to signal a shutdown of the takeup machine so the break can be repaired. A controller effective on startup of the takeup machine maintains the force at the high level for a predetermined interval and thereafter uniformly and smoothly decreasing the force.
