ABSTRACT:
In the method the auxiliary nozzles are used individually or in groups to form a pressure wave travelling together with the front end of the weft thread through the weaving shed. Individual auxiliary nozzles or groups of auxiliary nozzles are maintained in a cut-off position for a certain amount of time after the front end of the weft thread has passed, however, are again cut-in, particularly prior to the moment of time at which the weft insertion operation ends, so that a trailing travelling wave is formed. Using such method the air consumption can be maintained at low levels. Particularly when individual auxiliary nozzles are cut-in only for short intervals of time in the trailing travelling wave, a particularly low air consumption can be achieved. By employing a trailing travelling wave, a lower air pressure also can be used for generating the pressure wave travelling with the front end of the weft thread.
