Abstract
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.
