Multiple-color weft inserting apparatus of fluid jet loom

Abstract

A multiple-color weft inserting apparatus (60,70) of a fluid jet loom includes at least three weft supply lines (L), a weft-insertion controlling device (65,75). The controlling device (65,75) performs grouping of weft supply lines (L), and performs multiple-color weft insertion (60,70) in accordance with a predetermined weft-insertion pattern using the weft supply lines (L) in the group and at least one remaining weft supply line (L). The weft supply lines (L) in the group are where the weft of the same type is set. In the case where the controlling device (65,75) executes the insertion of the weft of the type corresponding to the group while the weft supply lines (L) in the group successively operate by turns, when the weft supply sensor (3) of any weft supply line (L) in the group detects a weft supply abnormality, the controlling device (65,75) excludes the any weft supply line (L) and continues the insertion of the weft of the type corresponding to the group using the other weft supply line or lines (L) in the group.

Description

technical field [0001] The invention relates to a multi-color weft insertion device of a fluid jet loom for weft insertion of different kinds of weft yarns according to a prescribed weft insertion pattern. Background technique [0002] The multi-color weft insertion device of the fluid jet loom has a plurality of weft yarn supply series. The weft yarn of each weft yarn supply series is transported to the warp opening for weft insertion by the fluid jet from each weft insertion nozzle sprayed according to the prescribed weft insertion pattern. [0003] The yarn supply sensor detects a yarn supply abnormality such as yarn breakage of the yarn supply bobbin or consumption of weft yarn, outputs a detection signal to the weft insertion control device, and stops the loom each time. For this reason, when weft yarns with low strength, weft yarns with a lot of fluff, or short weft yarns due to bulkiness (bulky) are detected frequently on the yarn supply drum, the loom will be stoppe...

AI Technical Summary

Problems solved by technology

For this reason, when weft yarns with low strength, weft yarns with a lot of fluff, or short weft yarns due to bulkiness (bulky) are detected frequently on the yarn supply drum, the loom will be stopped due to frequent detection of the yarn supply, thus reducing the efficiency of the loom. Run rate, meanwhile, produces stop weft stalls that damage the quality of the fabric
