METHOD FOR SETTING INJECTION PRESSURE OF FLUID JET TYPE LOOM, APPARATUS FOR SETTING INJECTION PRESSURE AND WEFT-INSERTING APPARATUS

PROBLEM TO BE SOLVED: To provide a fluid jet type loom facilitating setting of injection pressure of a weft-inserting nozzle in accordance with the change of yarn kind of goods in process, particularly the weft. SOLUTION: In a fluid jet type loom 1, a weft insertion ratio X is expressed as a variable in order to calculate a recommended value V of a set pressure of injection pressure of weft inserting nozzles (a main nozzle 4 and a subsidiary nozzle 5) and a plurality of formulas, e.g. a primary function formula V=AX+B are previously set in accordance with every yarn kind of weft and a formula corresponding to a yarn kind of the weft 6 is selected from the plurality of formulas and the recommended value V of the set pressure to the wert-inserting nozzle (main nozzle 4 and subsidiary nozzle 5) is calculated and output.
