Abstract
A device for greatly damping the oscillations and vibrations of weft yarns fed from a weft feeder to a loom, at the outlet of the feeder, particularly when yarn cutting takes place in the loom, comprises, in association with the conventional fixed yarn guide at the outlet of the weft feeder, a second fixed yarn guide, parallel to the first and downstream thereof, as well as an intermediate yarn guide, movable between a position in which it does not engage the weft yarn on its path between the two guides, and a position in which it engages the yarn and deviates it, forcing it to follow a winding path between the two guides. The positions of the intermediate yarn guide are controlled by an actuator and selected by the electronic circuit of the weft feeder, according to the working of the loom, so as to deviate the yarn when yarn cutting takes place.
