ABSTRACT:
Terry cloth is woven by determining the pile warp yarn consumption during partial and full beat-ups of the pile warp on the basis of reference pattern data established for the terry cloth that is to be woven and which is used to control the payout of pile warp several picks in advance of the pick when a given length of pile warp yarn is actually needed. A feed-back arrangement compares the required length of pile warp for any given beat-up with the length of pile warp actually paid out and makes adjustments to the pile warp payout mechanism to compensate for any differences between them. As the length of pile warp yarn between a supply thereof and the fell in the weaving machine varies, due to differences between the instantaneous rates of yarn payout and consumption and/or other factors, a compensating roller in engagement with the pile warp yarn keeps its tension constant to assure the weaving of correctly sized terry loops.
