摘要： Method and apparatus for producing and drawing-off a web-shaped product (2) with a production machine (1) and two clamp carriers (7.1, 7.2) with clamps (10.1, 10.2). The clamp carriers (7.1, 7.2) are driven moving back and forth parallel to a drawing-off direction of the web-shaped product (2). The clamp carriers (7.1, 7.2) are respectively drivable with a pair of drive spindles (14.1, 14.2), which are arranged in such a manner so that the web center of the web-shaped product (2) within the apparatus (6) extends in an area between the two drive spindles (14.1, 14.2) of the respective clamp carrier (7.1, 7.2). The method is characterized in that the web-shaped product (2) is produced with successive main sections (4.1, 4.2, 4.3, 4.4) and auxiliary sections (3.1, 3.2, 3.3, 3.4, 3.5), and that the clamps (10) are actuated in such a manner so that the opening and closing of the clamps (10) takes place only in the time segments of the production in which an auxiliary section (3.1, 3.2, 3.3, 3.4, 3.5) of the web-shaped product (2) is being produced.

摘要： The invention relates to a woven fabric of warp and weft threads with a construction in warp thread direction of at least first, second and third warp threads (11, 13, 12) running above one another, wherein: the third warp threads (12) always extend between the first and second warp threads (11, 13), the weft threads (16) are guided through alternating loom sheds (35, 36, 37, 38) between as well as below and above these at least three warp threads (11, 13, 12), and the third warp threads (12) consist of a different material than the first and the second warp threads (11, 13). Similarly the invention relates to a method for producing a multilayered woven fabric of warp and weft threads by means of a weaving machine.

摘要： A device feeds first and second weft threads in a weft direction to a gripper head of a loom and includes a coupling unit that moves back and forth in a warp direction. A first and a second feed unit are adjacently arranged in the warp direction on the coupling unit and are configured to feed the first and the second weft threads to the gripper head. A positioning unit moves the coupling unit in the warp direction in a first position of the coupling unit and counter to the warp direction in a second position of the coupling unit. The first feed unit feeds the first weft thread to the gripper head when the coupling unit is in the first position and the second feed unit feeds the second weft thread to the gripper head when the coupling unit is in the second position.

摘要： A weaving machine includes a shed forming device, a weft insertion device, and a weaving reed that beats up the weft threads at a beat up plane against an edge of the woven fabric. A guide device extends over a width of the woven fabric and is driven by a drive, the guide device being one or both of an upper guide unit that contacts a top surface of the woven fabric or a lower guide unit that contacts a bottom surface of the woven fabric. A control unit controls alternating movement of the guide unit along the direction of thickness of the woven fabric as the fabric is being woven based on information related to one or both of a structure of the woven fabric in the area of the beat up plane or a position of the warp threads in the open loom shed.

摘要： An apparatus for drawing-off a web-shaped product from a weaving machine in a drawing-off direction includes: at least one clamp carrier having clamps for the web-shaped product; a carrier frame apparatus on which the clamp carrier is guided; a drive arrangement by which the clamp carrier is drivable back and forth in a motion range; and a support system for the web-shaped product. The support system is arranged in an area between the apparatus side facing toward the weaving machine and the clamp carrier, within the carrier frame apparatus, in such a manner so that a sagging of the web-shaped product in this area is avoided or limited by the support system.

摘要： Apparatus and method for holding and feeding weft threads to the gripper of a weaving machine with drives, with which clamps for the weft threads are moved on motion paths into respectively a feed position, a transfer position and a ready position. The motion path of each clamp comprises a shape that is closed in itself. In that regard, the motion beginning of at least one of the clamps out of its ready position into its feed position takes place in a time segment that extends from the beginning of the beat-up motion of the weaving reed until the beat-up of the previously inserted weft thread against the beat-up line of the weaving machine.

摘要： The invention relates to an apparatus for the two-sided coating of at least one running flat material web (10),with a first and a second coating nozzle (2, 3), wherein the first coating nozzle (2) is providable to the first side of the flat material web (10) and the second coating nozzle (3) is providable to the second side of the flat material web (10), in order to coat the respective side of the flat material web (10), and wherein at least one, preferably both, coating nozzles (2, 3) are transferable from a working position into a maintenance position (A, W) and back, as well as with supply line sections (4, 8) with throughflow channels (4a, 8a) that are embodied therein and that are connected with one another in the working position (A) and that ensure a throughflow for supplying a hot, liquid coating material to the respective coating nozzle (2, 3), wherein, during the transferring of at least one of the said coating nozzles (2, 30) from the working position into the maintenance position (A, W), a first rigid supply line section and a second rigid supply line section (4, 8), which in the working position (A) enable a throughflow of the coating material to the coating nozzle (2, 3), are automatically moved relative to one another in such a manner so that the throughflow channels (4a, 8a) embodied in them are moved relative to one another in order to interrupt the throughflow of the coating material to this coating nozzle (2, 3).

摘要： A weaving machine with a shedding arrangement (10, 25) for forming loom sheds (3) between warp threads (1) drawn off from a thread supply (9), a weft insertion arrangement (20) for inserting weft threads (2) in the form of tapes into the formed loom sheds (3), and a drawing-off arrangement (30) for drawing off the woven fabric (4) formed by warp and weft threads (1, 2) after a weft thread insertion. The weaving machine encompasses a measuring arrangement (40) for detecting geometric parameters, especially the width, of a weft thread (2) before its insertion in the loom shed (3), as well as an evaluating arrangement (45) for evaluating the detected measurement results. A control arrangement (50) for controlling a motion of the woven fabric (4), including the drawing-off, based on the evaluated measurement results, is present on the weaving machine and is connected with the drawing-off arrangement (30).

摘要： A weaving machine includes a shed forming device, a weft insertion device, and a weaving reed that beats up the weft threads at a beat up plane against an edge of the woven fabric. A guide device extends over a width of the woven fabric and is driven by a drive, the guide device being one or both of an upper guide unit that contacts a top surface of the woven fabric or a lower guide unit that contacts a bottom surface of the woven fabric. One or both of the upper and lower guide units are positionable in a direction of thickness of the woven fabric to contact and guide the woven fabric in an area of the beat up plane. The guide section of one or both of the upper and lower guide units has a profiled shape in a weft direction to guide the woven fabric at different thicknesses in the weft direction.
