WEFT STORING AND DELIVERING DEVICE WITH PNEUMATIC THREADER |
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 The yarn is axially withdrawn from the storing drum over a free edge of the storing surface and through a substantially central guide opening.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.
