Abstract: A bringer gripper for looms without shuttles, where the weft yam is placed in an upper notch and in a gripping organ, particularly suitable for the simultaneous presentation of one or more wefts to the warp inlet and to the taker gripper, in which the upper notch is shaped with a multiple number of throats of different axial length. The weft yarns fit into the bottom of these throats and are essentially offset in the gripper's direction of motion.

Abstract: A modular device for weft yarn presentation in a shuttleless loom, operated by linear electric motors which present the yarn by using rods mounted on sliders which rotate to transition the rods from raised standby positions to lowered delivery positions. The linear motors include fixed plates and pivotally mounted sliders, each carrying a rod. The fixed plates are assembled such that the plates angularly diverge from one another from adjacent the pivotal mounting between the sliders and plates and form acute angles therebetween. By using this arrangement, the delivery segment for the yarns is significantly shorter and the angle of presentation of the yarns is substantially narrower.

Abstract: A device for weft yarn presentation in a shuttleless loom is operated by linear electric motors. The motors include fixed plates and movable plates pivotally mounted to the fixed plates. Yarn presenting rods are carried by the pivotal plates and rotate from raised stand-by positions to lowered delivery positions. The respective axes of rotation of the pivoted plates are arranged on a line skewed to the path of movement of the gripper so that the weft yarn delivery positions are close together.

Abstract: Device for selection and presentation of the weft yarns for high-speed looms, in which the mechanism of selection of the weft yarns comprises a set of collars, each equipped with an iron armature. The collars are slid through a free end of selectors and cooperate with a transverse lifting beam as well as with a corresponding set of permanent magnets equipped with a coil in order to nullify the magnetic field generated by the same magnet.

Abstract: A warp yarn tensioning device for a loom, in which the warp yarns are wound about a compensator roller through an arc of approximately 180.degree.. The roller is movable against the action of counteracting springs either by rotation or by translation in the direction of the thus wound substantially parallel warp yarns and is supported about an axis by bearings. The device operates in feeding the shed with yarns from the warp beam and in maintaining a constant yarn tension during loom operation. This is accomplished by supporting the compensator roll to undergo only a small amount of swing or translational movement in order to follow the warp yarn tension variations.
