  • 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.

  • Publication number: 20130333791
    Abstract: Weaving machine (1) for producing a woven fabric (9) with shedding means (4) for alternately raising and lowering warp material (3) for forming a loom shed (5), with weft insertion means (6), which are arranged stationarily in the warp direction in a weft insertion zone (14), and which are for inserting a preferably tape-shaped or band-shaped weft material (7) into the loom shed (5), with drawing-off means (8) for drawing off the finished goods or woven fabric (9) in a drawing-off direction (AR), as well as with means (13, 10) for the fabric movement in the warp direction, by means of which the fabric edge (12) is moveable back and forth in a goods movement range (WB) between a downstream initial position (AG) and an upstream collecting or pick-up position (AH), in order to bring the respective last inserted weft material (7) into contact with the fabric edge (12) in the pick-up position (AH), characterized in that furthermore upper and lower limiting means (16) are provided, which limit the opening of the lo
