ABSTRACT:
A fabric table (11) of a device (1) for altering a warp pile loop length during terry weaving is brought by a lever system from the starting position (V) into the partial beat-up position (T) and back again into the starting position (v). The lever system comprises a lever (18) and a drive (17, 171) acting at least roughly at right angles on this lever (18). The alteration in the distance (X) between the starting or complete beat-up position (v) and the partial beat-up position (T) of the fabric table (11) is performed by the displacement of the driving point (P) of the drive (17, 171) on the lever (18) and thus of the length of the effective lever arm of the lever (18). The separation achieved changing the position of the fabric table (11) between the complete (v) and the partial (T) beat-up position and of the actual backward and forward movement of the fabric table (11) permits an alteration and adaption of the fabric table travel and thus of the loop length.
