Abstract (en)

[origin: EP0939156A2] A method for the pneumatic threading of weft feeders (10) comprising a fixed drum (11), a hollow driving shaft (13), a hollow windmilling arm (12) which winds the thread onto the drum, braking means (14) and a final thread guiding ring (15). The method comprises the steps of: providing the feeder (10) with a first pneumatic element (18) and with a second pneumatic element (20) which are located at the infeed of the driving shaft (13) and at the output (15) of the feeder, respectively, and selectively activating the pneumatic elements in order to obtain the partial threading of the front part of the feeder (10) only, by guiding the thread (F) through the braking means (14) and the final thread guiding ring (15), or the partial threading of the rear part of the feeder (10) only, by activating the first pneumatic element (20) in order to guide the thread from the infeed of the driving shaft (13) to the base of the drum (11) through the windmilling arm (12). <IMAGE>
