Method for improving the weft inserting performance in an air jet loom and inserting nozzle for carrying out the method

摘要

The invention has for its object to provide a method for gentle entrainment of a weft thread when weft insertion and at the same time to increase the performance of the insertion nozzle and to specify an insertion nozzle for performing the method. According to the method, the object is achieved in that the expansion of an entry medium accelerated in the entry nozzle and the entrainment of the weft take place before the entry medium enters the mixing tube of the entry nozzle. For this purpose, the thread feed tube 3 of the feed nozzle 1 has a plurality of incisions 11 or openings 13, 14, 15 made in its circumference in the outlet end section 3a. IMAGE
