Abstract
A shuttleless loom weft brake includes at least two braking units arranged in series in the weft yarn travel direction and operating mutually out of phase. Each unit formed from a vertically arranged elastic blade at least partly of ferromagnetic material and a flat support plate of non-magnetic material, between which the weft yarn is made to travel. The blade is fixed to the frame of the weft brake by the end which is closer to the feed bobbin and is preloaded in a direction urging it away from said support plate and against a respective stop pin. The blade is pressed against the support plate by the attraction of an at least one electromagnet of adjustable excitation.
