Tuck-in method and tuck-in device for shuttleless loom

摘要

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.
