METHOD FOR CONTROLLING THE INSERTION OF A FRAME WIRE AND DEVICE FOR INSERTING FRAME WIRE IN AN AIR JET TYPE LOADING MACHINE

摘要

A method of controlling the insertion of a weft yarn into a loom which includes: a multitude of main nozzles disposed side by side in the front-to-back direction; a comb disposed downstream of the main nozzles and mounted on a leaf; and a multitude of secondary nozzles arranged along the passage for the insertion of the frame wire. The comb has a recessed passage for inserting the weft thread. The secondary nozzles include a first secondary nozzle which represents the nozzle closest to the main nozzles and a multitude of second secondary nozzles. The method further encompasses adjusting an injection pressure of the first secondary nozzle, lower than the injection pressures of the second secondary nozzles when the insertion of the weft yarn is carried out at least via one of the main nozzles which represents the process. nozzle closest to a pick clamp line.
