Device for weft cancellation on a weaving machine offers wefts (1), (2), (3) to at least one weft insertion (5), (6), (7) on a weaving machine, which can be operated in order either to bring a weft within the feed area of a weft insertion or to hold it out of this feed area, to effect a weft cancellation. The device has a yarn carrier (19) which can be moved by a weaving machine drive in order to bring a weft (2) within the aforementioned feed area. The device can be operated in order to bring the yarn carrier (19) and a weft (2) into a first and a second mutual position, in which this weft (2) can or cannot be carried along by the yarn carrier (19) within the aforementioned feed area. A first embodiment comprises a movable pusher element (22) that can be operated in order to bring a weft (2) into a first and into a second position in relation to the yarn carrier (19). In a second embodiment the yarn carrier (19) can itself be brought into two different positions.
Device for offering weft threads (1), (2), (3) to at least one weft insertion means (5), (6), (7) on a weaving machine, the device can be operated in order either to bring a weft within a feed area of the weft insertion means so that a weft can be inserted, or to hold it out of this feed area to effect a weft cancellation, characterized in that the device comprises a yarn carrier (19), a weaving machine drive connected to the carrier for moving the carrier to bring said weft (2) and the carrier within the aforesaid feed area, such that the weft (2) and the yarn carrier (19) are brought into a first and a second mutual position, and wherein the weft (2) in the first mutual position can be carried along by the yarn carrier (19) to the aforesaid feed area and wherein the weft in the second mutual position cannot be carried along by the yarn carrier to the aforesaid feed area.
Weaving machine comprising a device for offering weft threads to at least one weft insertion means on a weaving machine, the device being adapted to either bring a weft within a feed area of the weft insertion means so that a weft can be inserted, or to hold the weft out of the feed area to effect a weft cancellation, a yarn carrier, a weaving machine drive connected to the carrier for moving the carrier to bring the weft (2) and the carrier within the aforesaid feed area, such that the weft (2) and the yarn carrier (19) are brought into a first and a second mutual position, and wherein the weft (2) in the first mutual position can be carried alone by the yarn carrier (19) to the aforesaid feed area and wherein the weft in the second mutual position cannot be carried along by the yarn carrier to the aforesaid feed area.
