Abstract

The pile-to-ground warp yarn ratio of terry cloth is controlled during the weaving operation by sensing both the tension imposed on the pile warp and the amount of pile warp yarn dispensed from its supply beam. The sensed information is used to control the speed of a pile warp let-off motor which dispenses the pile warp yarn from its beam. Additionally, the sensed information is employed to selectively alter the displacement of a rocking bar to vary the height of the terry loop formed in the cloth.
