Abstract (en)
An electropneumatic device for the automatic threading of weft feeders (10) that comprise a fixed drum (11), a braking means (17) that elastically engages the drum, an inlet bush (19) and an outlet bush (20) for the thread, means (22-23-24) for producing, in the bushes, a pneumatic stream for entraining the thread that passes through the feeder (10) from one end to the other, passing in an intermediate channel (28), and a pneumatic pusher to disengage the braking means (17) from elastic contact with the drum (11) and allow the thread to pass. The pneumatic pusher (29) is arranged on the axis of the drum (11) and is actuated by a pneumatic actuator (30) accommodated in the drum and fed with a stream of air that is transferred into the drum by a distributor (31) arranged outside the drum (11) and can retractably move in order to avoid hindering the free unwinding of the thread (F) from the drum when the threading device is inactive. <IMAGE>
