ABSTRACT:
A system for maintaining a constant terry height in forming a terry cloth despite loom stoppage, e.g., to correct yarn breakage. The system includes a proximity sensor which is positioned at a predetermined distance from a floating roller, and on the same side of the floating roller as a loading spring. The proximity sensor causes stoppage of an electric motor of the feed beam for the terry warp yarns which were previously driven in a forward direction by the electric control center. Upon sensing movement of the floating roller by a predetermined distance, the electrical control sensor causes motion inversion of the electric motor to reverse the movement of the feed beam for the terry warp yarns.
