  • Patent number: 9328437
    Abstract: Apparatus for the intermediate storage of two band-like weft materials (1, 21) for a weaving machine (3), with two storage containers (7, 27) in which respectively a U-shaped loop (12, 22) of a weft material (1, 21) can be formed. Machine elements (14, 34) for the application of tensile forces (15, 35) onto the weft material (1, 21) in the inner space (9, 29) of the respective storage container (7, 27) are present. The inner spaces (9, 29) of the two storage containers (7, 27) respectively orient one of their two narrow sides (10, 30) toward one another. Deflection elements (16, 36) are respectively arranged on the storage container (7, 27) in such a manner so that the respective weft material (1, 21) can be supplied to the inner space (9, 29) in a region (17, 37) that lies closer to that one of the two narrow sides (11, 31) of this inner space (9, 29), which is not oriented toward the inner space (9, 29) of the respective other storage container (7, 27).

  • Patent number: 8939179
    Abstract: A weaving machine for producing a woven fabric has a shedding device to form a loom shed of warp material, a weft insertion device for inserting a preferably tape-shaped or band-shaped weft material into the loom shed, a drawing-off device for drawing off the finished fabric in a drawing-off direction, fabric movement device for moving the fabric back and forth in the warp direction to bring the last inserted weft material into contact with the binding point or fabric edge. A shed limiter device limits the opening of the loom shed from above and below the warp, and is movable back and forth in the warp direction. The shed limiter device only loosely bounds the fabric and essentially without actively clamping or pinching or contacting the fabric and/or the last inserted weft material, at least while moving in the direction opposite the drawing-off direction.

  • Patent number: 8550123
    Abstract: For transferring a preferably band-shaped weft material from a feed unit to an insertion element of a weaving machine, a free end of the weft material is clamped in a clamping device, the free end is transferred to the insertion element, and then the clamping device is opened to release the weft material, which is then inserted by the insertion element. The clamping device is conveyed by a drive essentially in the direction of motion of the insertion element between at least two different operating positions.

  • Publication number: 20120125476
    Abstract: A device (1) for transferring a preferably band-shaped weft material (6) from a feed unit to an insertion element (4) of a weaving machine comprises a clamping device (5) for clamping a free end (E) of the weft material (6). The clamping device (6) is conveyable essentially in the direction (BR) of motion of the insertion element (4) between at least two different operating positions. The device (1) includes a drive (8) for conveying the clamping device (5). In a method for transferring a preferably band-shaped weft material (6) from a bobbin or a feed unit to an insertion element (4) of a weaving machine, a free end (E) of the weft material (6) is clamped in a clamping device (5), the free end (E) is transferred to the insertion element (4), and then the clamping device (5) is opened and the weft material is inserted. The clamping device (5) is conveyed by means of a drive (8) essentially in the direction of motion of the insertion element (4) between at least two different operating positions.

  • Patent number: 7537029
    Abstract: A thread clamping device is provided for a jet weaving machine that has a main discharge nozzle (1) with a mixing tube (2) for inserting a weft thread (3) into a shed with a conveying fluid discharged from the main discharge nozzle. This clamping device is placed inside the mixing tube (2) in the area from which the weft thread exits, and has an actuator, which is situated outside of the mixing tube (2), and a lever connected to the actuator so that this lever is actuated by the actuator (6) to execute a tilting or pivoting motion whereby the weft thread is clamped between the lever and an abutment (9) in an opening of the mixing tube.

  • Patent number: 7481249
    Abstract: A reed drive of a loom includes a reed shaft connected to a reed. A conversion gearing having an input element and an output element is provided at each end of the reed shaft. The input elements are coupled to driven shafts of electromotive rotary drives to produce a common rotational motion with the same rotational speed as the driven shafts. The conversion gearings convert the rotating motion of their input elements into a reversible rotation of the output elements, and the output elements are coupled to the reed shaft in a rotationally fixed manner. Thus, the number of complete rotations of an input element is equal to the number of complete motion cycles of the reed shaft per unit of time.

  • Publication number: 20080099095
    Abstract: A reed drive of a loom comprises a reed shaft (3) connected to the reed (1). A conversion gearing (7, 8) each having a respective input element (11, 12) and a respective output element (13, 14) is located at the ends of the reed shaft (3). The input elements (11, 12) are coupled to the driven shafts (23, 24) of electromotive rotary drives (19, 20) for effecting a common rotational motion of the same rotational speed. The conversion gearings (7, 8), alone, serve to convert the rotating motion of their input elements into a motion of the output elements (13, 14) whose direction of rotation can be reversed. To this end, the output elements (13, 14) are coupled to the reed shaft (3) in a rotationally fixed manner.

  • Patent number: 6390144
    Abstract: Ground warp and pile warp thread sheets are supplied to a shed forming device. The ground warp and the pile warp are separately deflected over a deflecting rod upstream from the shed forming device. The deflecting rod supports the ground warp and directs the pile warp to cross and interpenetrate through the ground warp before deflecting the pile warp into the back shed. The deflecting rod is positively driven and controlled to pivot about a horizontal axis to provide a positive controlled partial compensation of the pile warp thread length variations. The pile warp also runs over a pile warp thread reserve and compensating device upstream from the thread crossing location to provide an additional passive uncontrolled compensation of the pile warp thread length variations and to provide a pile warp thread reserve during the pile loop formation and/or the shed changes in the weaving process.
