ABSTRACT:
A device and weaving machine using the device for cutting discarded pile loop weft yarns in a fabric that is composed of a backing fabric consisting of weft yarns and warp yarns and that contains pile warp yarns by which, in one or several zones, pile loops are formed over discarded pile loop weft yarns, device being provided with a cutting blade to cut the discarded pile loop weft yarns, the device comprising a guiding needle that extends between two rows of pile positioned side by side in the direction of the warp, and the device being provided with two or several guiding yarns in the direction of the warp that push this side by side positioned pile away from the guiding needle and the cutting blade in the direction of the weft and that, at the same time, pull the discarded pile loop weft yarns away from the backing fabric in order to present them over the guiding needle to the cutting blade so that they can be severed.
