Abstract (en)
[origin: EP0478986A1] The weft selecting and feeding device contains an electronically controllable electric motor 2 having a driving wheel 4 and a deflecting wheel 5 and a toothed belt 6 which loops round these wheels. Yarn feeders 7, 7a are so fastened offset to one another on the two longitudinal strands of the toothed belt 6 that one yarn feeder 7a is in the position of readiness B and the other in the transfer position U. The yarn feeders 7, 7a possess a yarn eye 9, through which the weft yarns 17, 17a run. In the position of readiness B, the weft yarn 14a is outside the take-up region of the weft-insertion member 15; in the transfer position U, the weft yarn 17 is presented to this. According to the particular pattern and in synchronism with the weaving cycle, the electric motor 2 rotates the driving wheel 4 and thereby moves the toothed belt 6, the positions of the yarn feeders 7, 7a being positively interchanged. <IMAGE>
