| 21 | Gripper guide for double-gripper weaving machines | US782648 | 1991-10-25 | US5183083A | 1993-02-02 | John Debaes |
| Gripper guide for double-gripper weaving machines, comprising two bearing arms (5) and (5') running above one another and adjustable individually in the warp direction. An L-shaped guide strip (7), (7') is fixed to each bearing arm (5), (5') so that it is adjustable in height. In front of each guide strip (7), (7') there is a straight guide strip (8), (8') which forms a U-shaped channel for the gripper bars (4), (4') together with each of the first mentioned guide strip (7), (7'), so that the gripper bars do not swing. The straight guide strips (8), (8') are adjustable both in the warp direction and in height and are easily and quickly removable from their guide position, for example, through a hinged connection to the respective bearing arms (5), (5'), which permits the upper guide strip (8) to flap up and the lower guide strip to flap down. At the level of the drive gear wheels (2), (2') on the guide strips (8) and (8') at least one roller (20), (20') is disposed on a vertical shaft (21) in order to guide the gripper bars (4), (4'). | ||||||

| A gripper rod for a shuttleless loom has a toothed rack section made of fiber reinforced synthetic composite, preferably thermoplastic, material. The toothed rack is made of a stack of belts of such material with rectangular perforations increasing in size from the inside out or from the bottom up. By compressing and simultaneously heating the stack the matrix material is cured, whereby the belts are bonded to one another. The gaps between the teeth may extend entirely through the rod or the rod may have a base also made of such belts but not having any perforations. | ||||||
| 23 | Apparatus for presenting weft threads to the clamps of gripper rods in shuttleless looms | US842635 | 1986-03-21 | US4655263A | 1987-04-07 | Peter Dornier; Valentin Krumm |
| A shuttleless loom is equipped with a displacement device for the control member or rail of the clamping device of the gripper, whereby the control rail can be displaced in parallel to the thread inserting motion of the gripper. This displacement of the control rail permits the proper presentation and transfer of the weft threads into the clamping device of the gripper even if the weft thread fan contains a substantial number of weft threads. This control rail displacement in the direction of the thread insertion into the loom shed takes place at each picking or inserting movement of the gripper and is substantially synchronous with the gripper motion after a thread transfer. When the number of threads in the thread fan is relatively small, the displacement device can be switched off. | ||||||

| 28 | Method and apparatus for reducing weft waste in a gripper weaving loom | US10401938 | 2003-03-27 | US06938648B2 | 2005-09-06 | Wilhelm Herrlein; Manuel Renz |
| In a gripper weaving loom which weaves several different types of weft threads into a fabric, it is desirable to keep weft material waste to a minimum. For this purpose a weft thread (7) already inserted into the loom shed is simultaneously held by a weft presenting clamp (13) and by a holding clamp (18). As soon as the weft is held by both clamps the weft is cut by a cutter (20) effective between the two clamps to form a trailing weft end (7B) of the already inserted weft and a leading weft end (7A) of a weft yet to be inserted. The holding clamp (18) keeps holding the trailing end (7B) until beat-up of the weft by the reed (4) is completed. For this purpose, the holding clamp (18) moves with the reed (4) into the beat-up position. When beat-up is completed the holding clamp (18) releases the trailing weft end (7B) and returns into a weft receiving position (22B). The weft presenting clamp (13) still holds the leading end (12A). The holding clamp (18) is arranged to move with the reed, while the cutter (20) is stationary between the two clamps. | ||||||

| 32 | Apparatus for the constrained actuation of the clamping system of filling yarn inserting members in shuttleless weaving machines | US591412 | 1984-03-20 | US4558722A | 1985-12-17 | Fritz Gehring; Stephan Arndt; Harald Storr |
| In a shuttleless weaving machine wherein the filling yarn is inserted from both sides of the shed by means of gripper systems provided with filling yarn clamping devices and advanced into and then retracted from the shed. The filling yarn is transferred from one gripper system to the other by a controlled opening and closing of the clamping devices. For this purpose, a guide rod mounted in a straight guide on the reed stay and displaceable toward the shed is provided, which is equipped at its end with a control finger. The control finger passes through the warp yarns of the shed and actuates the clamping device in the shed. The control motion is transmitted through a cam follower roller mounted on a rocker lever hinged to a coupling link which in turn is pivoted or hinged to the guide rod. The control finger is entirely pulled downwardly out of the shed for the reed beat-up. The masses which must be accelerated together with the reed are low and control finger vibrations are eliminated. | ||||||
