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.

The arrangement for removing a faulty weft yarn from a shed comprises a manipulator for physically moving a yarn clamp carrier between a rest position and a yarn clamping position for engaging a weft yarn. A needle is provided on the carrier for releasing the weft yarn from the beat-up line of the cloth for delivery into the yarn clamp. A rotatable storage drum at a yarn release position winds on yarn from the yarn clamp for subsequent delivery to a suction tube for removal.

Apparatus for removing a faulty weft yarn from a weaving shed

An auxiliary member or accessory serves to reduce or limit the length of a weaving reed for the purpose of adapting it to the desired weaving width, so that the same reed can be used for differing weaving widths. The auxiliary member or accessory can be a stretching device or a detection device for the inserted weft threads. A flange of the auxiliary member is inserted between two reed lamallae or dents and is fixed on the rear side of the read by means of a locking element.

This weaving machine comprises a device for removing faulty weft threads from the weaving shed or the woven cloth respectively, also if they have already been cut from the yarn supply during the weaving cycle. The device has a reciprocatable mechanical removing member (8) by means of which also fibrous yarn threads may be removed from the beating up line. Furthermore the device comprises a catching element (10) for threads which have already been cut, which element is adapted to clamp and take along the thread.
