Abstract
Method for threading a weft insertion device on weaving machines, in particular for threading a weft insertion device of the type which consists of at least one first nozzle (3, 4) mounted beside the sley (7) and at least one second nozzle (5, 6) which moves with the sley (7), where the first nozzle (3, 4) makes an angle with the second nozzle (5, 6) and during normal operation of the weaving machine lies at a distance from it, with the characteristic that the method consists essentially of presenting to one another the thread exit opening (17) and thread induction opening (15) of the first and second nozzles respectively (3, 4; 5, 6), and then leading a weft thread (19, 20) through both nozzles (3, 5; 4, 6); the invention also concerns a device which uses this method.
