ABSTRACT:
Two different pile heights (a, b) can be selectively formed during the weaving of terry fabric on a loom by shifting the fabric with its actual beat-up line (10a) back and forth relative to a base beat-up line (3). First and second fabric shifting oscillating motions are performed by first and second power or motion transmission couplings (4, 11) driven through eccentric drives (5, 12) from a main loom drive shaft (DS) and controlled through valves by a central loom control (22) in such a way that a second oscillation with a different amplitude is superimposed on a first oscillation between beat-up groups of weft beat-up motions including partial weft beat-ups and a full weft beat-up motion of a reed (2) in the loom. Different oscillation amplitudes cause a beat-up line shift of different length (a or b) whereby different pile heights are formed.
