Abstract

Clutches in rotating drives of spools feeding threads to a weaving or knitting machine are disengaged when respective gravity-biased travelling compensating pulleys reach their lower limits and are reengaged when the respective pulleys reach their upper limits. The variable loops of thread formed by the compensating pulleys compensate for different speeds of thread take up by the machine.
