Abstract (en)

[origin: EP0504110A1] The apparatus prevents formation of a swelled weaving bar which is caused by interference of the reed and the cloth fell during slow rotation of the loom in forward or reverse direction. The let-off motor (1) is rotated at a slow rate in forward direction in advance of the subsequent slow forward or reverse rotation of the main motor (M) for removal of a faulty weft yarn. Operation of the let-off motor (1) is controlled by a computer control (C) and the motor is forward rotated for a predetermined amount so as to displace the cloth fell (W1) toward the fabric (W, or retract it away from the swinging area of the reed 6. In restarting the weaving operation, the let-off motor (1) is slow rotated in reverse direction to return the cloth fell to its original position. The rotation of the let-off motor (1) is monitored by the rotary encoder (1a) incorporated therein and connected to the computer control (C 1a) so that the control (C) can determine whether or not the cloth fell displacement is accomplished properly. In the event of any abnormality in the cloth fell displacement, the warp tension detected by the load cell (15) is restored to the tension (F) detected by the load cell immediately before the commencement of the cloth fell displacement. <IMAGE>
