Abstract
On an air jet loom, one or more accelerator tubes are arranged in between a main jet nozzle and yarn guides or the like in axial alignment with the main jet nozzle preferably in an axially rotatable fashion in order to increase weft transportation energy of the air flow carrying the weft by sucking ambient air into the accelerator tube. Remarkable increase in travelling speed of the weft under unchanged air pressure or appreciable reduction in power consumption with unchanged travelling speed of the weft can be expected.
