Abstract: A weft threads saving device for shuttle-less weaving machines includes a comb (2), a temple (3), a guiding plane (6), a fixed blade (4), a movable blade (5) of a shear (17), a fabric winding cylinder (8) and a suction system (7) connected both to the guiding plane (6) and to the fixed blade (4) of the shear (17).
Abstract: An assembly and method for automated cutting of undesired stretched yarn in a yarn system. Stretched yarn can hang away from the yarn system differently than desired yarn. A cutter head is positioned a predetermined distance relative to yarn traveling through the yarn system so that the stretched yarn is cut by the cutter head and the desired yarn passes the cutter head without being cut. A plurality of cutter heads can be used to cut stretched yarn hanging away from the yarn system in different locations.

Abstract: A device for cutting the weft yarn in weaving looms includes a fixed-blade and movable-blade cutting group which has associated motor for the cutting movement of the movable blade in order to perform cutting of the weft yarn. The fixed and movable blades are each mounted on the end of respective elongated blade-carrying arms which extend respectively above and below the fabric holder of the loom, as far as a cutting zone located beyond the leading edge of the fabric holder itself in the direction of the reed, a zone in which said blades overlap so as to perform cutting of the weft.
