Abstract
A weft storage device has a drum around which a weft yarn is wound by a rotatable yarn guide, weft yarn withdrawal from the drum being controlled by a movable engaging pin. When the weft yarn breaks, any yarn remaining on the drum is cut off and the scraps are withdrawn by a suction arrangement. The yarn guide is moved to an angular position near the suction arrangement so an end of the yarn is held by the suction arrangement, and then to another angular position. A guide part then engages the yarn between the suction arrangement and yarn guide and moves it to the inlet of an injection nozzle, the air flow in the nozzle then threading the yarn into the nozzle. The engaging pin is then actuated to hold the yarn on the storage drum, and the yarn guide then winds a predetermined number of turns of the yarn onto the drum.
