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.

Pile warp dispensing in advance of beat-up in a terry loom

A method for weaving blemish-free smooth and terry fabric on a loom following a stoppage of the loom after it has woven a fabric fell which terminates in a last weft thread. The loom has a driven reed which reciprocates during normal weaving towards and away from the fell over a predetermined beat-up distance to successively position additional weft threads at predetermined target positions which assure a uniform, blemish-free fabric. Following a loom stoppage, the next weft yarn, for smooth fabric, and a plurality of next weft yarns, for terry fabric, are moved towards the last weft yarn over a compensated beat-up distance which is different from the predetermined beat-up distance to thereby position the next weft yarn at the desired target position relative to the least weft yarn of the fell to avoid the formation of fabric blemishes. Thereafter the reed is again moved over the predetermined beat-up distance during subsequent picks of the loom.
