<p>The tuck-in device in the shuttle includes a tuck-in needle (5) that swings reciprocally across warp yarns (T). The end of the weft yarn (Y) is held by an air-operated weft holding mechanism (8, 8b, 9, 9b, 18) in an ready-for-threading position. When the tuck-in needle (5) is in the threading position an air-operated weft threading mechanism (8, 8a, 9, 9a, 17) transfers the end of the weft thread (Y) to the threading hole (5b) of the needle (5). The holding and the threading mechanism does each include either a suction or a blowing jet nozzle (17, 18). The tuck-in needle (5) includes further a guide edge (5a) that extends obliquely with respect to the direction of the warp yarn (T) therebye forming a pointed tip end (5e). The needle (5) is mount in a way that its tip end (5e) is spaced farthest from the cloth fell (W1) when the needle (5) is moved into the threading position. <IMAGE></p> |
