ABSTRACT:
A weft selection device for a weaving machine has at least two drop wires with feed-through eyes. The drop wires are fixed rotatably in two planes lying above one another to take a weft thread extending through the feed-through eye within or beyond the reach of a gripper. Each drop wire has a bent end containing the feed-through eye. The drop wires are fixed rotatably in pairs on common fixing device. The top drop wire of each pair is bent upwards and the bottom drop wire of each pair is bent downwards. A free space is provided above and below the fixing device of each pair to allow through unimpeded the weft threads. Thus, it allows for an arrangement with a minimum angle of bend of the weft threads after they have passed through the feed-through eyes. The present weft change motion is suitable for coarse and stiff yarn.
