<p>PURPOSE: To avoid the reed collision during return motion and to prevent the occurrence of a weaving defect by continuously rotating a spindle and a heald mechanism together at a prescribed angle via a transmission device after loom stoppage by a weft thread defect, then disconnecting the coupling and reverse rotating both. CONSTITUTION: At the time of the return movement of a drive section 16 of the spindle 17, a reed shaft and a heald mechanism 15 to the respective rotating angle after the restart after the loom is stopped by the weft defect and the faulty weft defect is removed, the spindle 17 and a drive shaft 16 are further continuously rotated by the angle smaller than 360 deg. via the transmission device 13 and thereafter the coupling of the spindle 17 and the drive shaft 16 is disconnected. The spindle 17 and the reed shaft are then rotated backward at the rotating angle smaller than 360 deg. and the drive shaft 16 is rotated backward at the angle larger than 360 deg. and thereafter, the drive shaft 16 and the spindle 17 are connected again and the return motion is smoothed. The transmission device 13 interlocks the spindle 17 and the drive shaft 16 by a belt 18 and is constituted to have a clutch 22 of 1:2 to 1:3 in a speed increasing transmission ratio between the drive shaft 16 and a driven shaft 14a.</p> |
