<p>A device for actuating weft-carrying lances on looms, characterised by kinematic coupling to the frame of the loom, which is positively driven by a cam shaft, crank and connecting rod mechanism, and a T-shaped component articulated at the foot to the frame, which has a toothed circular segment on the head engaging with a pin also fixed to the frame. It is carried out by means of a lever mechanism basically consisting of two rods, both connected to the frame, which have an elongated hole for regulating the travel, and a T-shaped part mounted on the frame.</p> |
