device field damper vibration and vibration of the wires in the plot to plot device feeds air frames

摘要

A device for greatly damping the oscillations and vibrations of weft yarns (f) fed from a weft feeder (1) to a loom, at the outlet of said feeder, particularly when yarn cutting takes place in the loom, comprises, in association with the conventional fixed yarn guide (3) at the outlet of the weft feeder (1), a second fixed yarn guide (4), parallel to the first and downstream thereof, as well as an intermediate yarn guide (5), movable between a position (AA) in which it does not engage the weft yarn (f) on its path between the two guides (3,4), and a position (BB) in which it engages said yarn (f) and deviates it, forcing it to follow a winding path between said two guides. The positions (AA,BB) of the intermediate yarn guide (5) are controlled by an actuator (6) and selected by the electronic circuit of the weft feeder (1), according to the working of the loom, so as to deviate said yarn (f) when yarn cutting takes place.
