Abstract
The weft yarn clearing device is of use for an automatic method of clearing weft breakages in projectile looms. In the event of the yarn breakage in the shed, the weft yarn is engaged in the shed by at least one gripper element, then supplied to the inlet of an extractor and placed between the rollers of a pair of draw-off rollers. The rollers draw the weft yarn out of the shed and the weft yarn is simultaneously supplied by the extractor to a collecting receptacle. The clearing device can also be used for a yarn breakage before the shed.
