摘要： A yarn storing and delivering device for a weaving machine includes a stationary base body and a hollow shaft which is rotatably mounted in the base body and which carries a laterally projecting yarn feeder element. Yarn is guided into the hollow shaft and wound by the yarn feeder element onto a storing surface of a storing drum which is maintained stationary relative to the base body. The yarn is axially withdrawn from the storing drum over a free edge of the storing surface and through a substantially central guide opening. A threading device equipped with air jet nozzles is provided for automatically threading the yarn up to a location within the guide opening. The threading device includes a compressed air conveying system disposed between the guide opening and a location adjacent the outlet of the yarn feeder element. The compressed air conveying system includes a plurality of stationary directional jet nozzles which, when activated, provide an air flow which delivers the yarn to the guide opening.

摘要： 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.

摘要： A feed mechanism for several weft yarns, each with its own feed device capable of selecting the weft yarn to be inserted, includes sensors for monitoring the weft yarns for quality defects and for, upon detection a defect in a weft yarn, precluding the weft yarn from being selected for insertion until the portion of the weft yarn with the defect has been shunted into a region from where it can no longer be woven into the fabric.
