Abstract
A method for controlling weft insertion in an air jet type loom, includes setting an upper limit and a lower limit with respect to the running property of a weft yarn to be inserted through a shed of warp yarns by way of a main nozzle and a plurality of groups of sub nozzles arrayed in the running direction of the weft yarn, and causing air jet end timings of the respective groups of sub nozzles to become later when the running property of a weft yarn is lower than the lower limit, and air jet start timings of the respective groups of sub nozzles to become sooner when the running property of a weft yarn is higher than the upper limit. This method enables stable weaving of high-quality fabric while minimizing air consumption by properly regulating both the air jet start timing and the air jet end timing of sub nozzles of the air jet type loom, considering variation in the running property of a weft yarn.
