An air jet tuck-in device for use in a shuttleless loom for weaving a fabric (1) including a plurality of weave sections having different weft densities includes one or more tuck-in nozzles (4) disposed at a side of a row of warp yarns for tucking an end portion (2a) of a weft yarn into a warp shedding (30) after weft insertion; switching means (5) that switches an ejection position of the tuck-in nozzles (4) between a first ejection position that corresponds to a first weave section (1a) and a second ejection position that corresponds to a second weave section (1b); and control means (6) that selects the ejection position of the tuck-in nozzles (4) and operates the switching means (5) on the basis of a result of the selection, the selection being performed on the basis of a signal related to an input weft density or a weaving condition associated with the weft density.

The invention relates to a method for tucking an end (23) of a weft thread (19) into a selvedge (27) of a fabric (3) by means of a pneumatic tuck-in device (5) which blows an end (23) of an inserted and beaten up weft thread (19) extending past a selvedge (27) of the fabric (3) into a subsequent shed (1), whereby the tuck-in device (5) is moved back and forth along the selvedge (27) of the fabric (3) in synchronization with the reed (13) and blows in of this end (23) of the beaten-up weft thread (19) into a shed (1) while the tuck-in device (5) moves back and forth along the selvedge of the fabric.
摘要:
The invention relates to a tuck-in selvedge motion (1) for a weaving machine, for tucking an end of a weft yarn into a shed. According to the invention, a holder (15) is provided with a rotationally arranged insert (33) which is connected to a source of compressed air and which has at least one blasting opening (37). The blasting direction of said blasting opening can be adjusted by changing the position of said blasting opening (37).
