Abstract: Gripper band (1) for a gripper weaving machine with a first part (13),a second part (14)and two longitudinal ribs (21), el wherein a thickness of the second part (14) near a centerline (31) of the gripper band (1) is larger than a thickness of the first part (13) near the centerline (31) of the gripper band (1), and in that the gripper band (1) comprising the first part (13), the second part (14) and the longitudinal ribs (21) is one single, integral structure formed of composite material. Gripper unit for a gripper weaving machine with a gripper (2, 3) and such a gripper band (1).

Abstract: A receiving gripper for a rapier loom, wherein at least the moving part is made of a ceramic material.

Abstract: The invention relates to a receiving gripper for a rapier weaving machine, the gripper being fitted at one end with a clamping hook (12) including a clamping surface, the hook being paired with a mating clamp face of a head (15) of a pivotably supported, two-arm lever (14), wherein both the end face of the head (15) and the clamping hook (12) are fitted with guide elements (18, 19) guiding the lever head in the circumferential direction relative to a pivot pin for the lever.

Abstract: A receiving gripper for a rapier loom, wherein at least the moving part is made of a ceramic material.

Abstract: In a rapier for a gripper loom, the rapier is made of synthetic material and includes at least one layer of reinforcing fibers. The gripper is mounted at the front end of the rapier, and the layer of reinforcing fibers begins at a distance away from said front end.

Abstract: A gripper loom includes guides mounted laterally outside the shed and guides displaceable into and out of said shed. Both guides engage guide surfaces of a rapier to guide the rapier, but the set of guide surfaces engaged by the guides mounted laterally outside the shed and the set of guide surfaces engaged by the guides displaceable into and out of the shed are located at different sites on the rapier.

Abstract: A mechanism for presenting weft threads on rapier weaving machines includes a cam mechanism, cam follower devices, armatures connected to the cam follower devices, and thread presentation arms. The cam mechanism and cam follower devices impart reciprocating movements to the armatures such that, alternately, for each successive weaving cycle, the armature connected to one of the cam follower devices cause the movement of one of the thread presentation arms into a presented position, while the armatures connected to the other cam follower device move back to a rest position a thread presentation arm which has just been presented.

Abstract: A thread clamp, with the characteristic that it consists essentially of: a first jaw (3) with two spring arms (4, 5) which bend elastically away from and towards each other, perpendicularly to the plane in which the thread clamp opens and closes; a second jaw (6) which operates in conjunction with the first jaw; and an elastic device which serves to press the two jaws (3, 6) together.

Abstract: A weft carrying gripper is configured to have a small, open sided profile and includes a weft thread gripping jaw portion that is pivotally mounted by a broad hinge pin in lever fashion to the body of the gripper such that the weft clamping element tends to tighten in the clamp closing direction if inadvertent contact occurs between the weft carrying gripper and the weft drawing gripper. Various clamping and thread guiding arrangements are described.

Abstract: Apparatus for clamping, holding and presenting weft threads in a weaving loom is disclosed having: a movable clamp for each weft thread which keeps the corresponding weft threads clamped at their thread ends; thread guiding devices guiding of the weft threads from a supply to the corresponding clamp; and a driving and control mechanism for bringing a clamp successively into three positions for inserting the selected weft thread. The first position of the clamp is a storage position; the second position is located such that the weft thread between the clamp and the thread guiding devices is in the path of a gripper; and in the third position the clamp is located on the weft side near the cloth edge adjacent to the fell. Hooks fastened to the reed bring the insert weft thread back into the clamp during the beating movement of the reed. The hooks also act as a guiding element during the presentation of the weft thread to the gripper.

Abstract: A driving and control mechanism for clamping, presenting and holding weft threads on gripper weaving looms is disclosed, whereby at least one thread presentation element (1) can be moved to various positions. The mechanism is composed of at least two levers (5, 6) which are attached in a common manner with a coupling connecting the levers (5, 6) to a thread presentation element (1), a cam transmission (8, 9) for moving the levers (5, 6) locking device (10) which can actuate the lever arms (17, 18) located opposite to the lever arms (12, 13) attached to the coupling (7); and a control system (11) for actuating the locking device (10).
