Abstract: Drawing gripper for weaving looms with continuous weft feed comprising a claw ending into a hook and an oscillating element, rigidly cooperating with each other for holding the weft thread grasped by the hook, said element being caused to oscillate about its own longitudinal axis by being pivoted into a support of the gripper body as well as into the hook end of said claw.

Abstract: A weft carrying gripper for shuttleless looms with stationary weft supply, comprises a lower jaw whose relatively stationary upper surface is adapted to contact the weft. A rigid lever pivoted on the gripper carries a metallic lamina at one end that releasably grips the weft thread between itself and the stationary surface of the lower jaw. The same end of the lever also carries a leaf spring that bears resiliently against the lamina. A further leaf spring at the other end of the lever contacts an adjustable portion of the gripper to swing the lever in a direction to urge the lamina toward its weft-gripping position. That other end of the lever serves as a cam which when depressed releases the weft thread.

Abstract: A device for weft tensioning adjustment in weaving looms of the type having continuous weft feed, to be applied at the side of the loom. The device comprises - mounted on a single support - a pair of elastic resilient laminae, biased into mutual contact with an adjustable pressure knob and arranged in the path of the weft thread being supplied, for engaging said thread between them and providing for the braking thereof, and an oscillating lever ending with a threadguide, through which eye is passed the weft thread, after engagement between said laminae and before reaching carrying members, said oscillating lever being adjustably urged by spring means to move away from said laminae and from said members, in order to take up slack in said weft thread when it exists.

Abstract: A weft presenting device for looms with selective weft feed, of the type wherein presenting rods are operated one at a time by respective control magnets, so as to be ejected from the device itself for presenting their own weft thread, provides for each single rod to be positively controlled, during both its advancing and its return motion, by a mechanism controlled by a cam, wherein a pawl interlocked with the control magnet locks, when energized, the end of a lever of said mechanism, to impose on said lever the movements for operating the back and forth motions of the rod; while, when de-energized, said pawl frees the end of said lever, allowing the same to perform idle movements.
