ABSTRACT:
The present invention relates to means for controlling and for cutting the weft threads in looms with weft inserters. The combination of the means for controlling and for cutting the weft threads comprises a thread cutter carried by the loom framing, as well as a threader and a lowering hook carried by the sley. The thread cutter is constituted by a vertically-movable knife which co-operates with a component provided towards the rear with a weft thread retaining hook. The knife has, towards the rear, an extension for guiding the weft thread into the shed. The threader is formed by a horizontal ramp ended at its rear by an upwardly and forwardly open loop, located above the path of the entry needle, while the lowering hook may adopt, selectively, a high position above the weft thread portion connecting the threader loop to the cloth and a low position in which it presses down and holds one point of said weft thread portion below the path of the nippers of the entry needle. The invention is applicable to loom with weft insertion needles, especially for the manufacture of cloths which comprise effect or fancy threads.
