How to set warp and weft flight information on an air injection loom

摘要

To provide a setting method of weft travel information required for setting an injection mode of a sub-nozzle at an initial setting stage in an air jet loom.SOLUTION: In a setting method of weft travel information in an air jet loom in which a weft insertion is executed in accordance with a weft insertion condition including an injection mode of each sub-nozzle and a target weft-arrival timing, a first position located on a yarn feeding side and a second position located on the side opposite to the yarn feeding side are determined in a weft travelling path from the weft insertion start position to the weft arrival position in the weaving width direction, then a flying line obtained from weft flying information is drawn in such a figure as to bend at a first flexion point K1 located at the first position and a second flexion point K2 located at the second position, and the second flexion point is set based on both the rotation angle of a main shaft of the loom determined by the target weft-arrival timing and the second position.SELECTED DRAWING: Figure 3
