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 two-dimensional fabric (20) used to produce a three-dimensional composite part has a binding system (21) with binding warp threads (23) and/or binding weft threads (24) and a reinforcing system (22) with reinforcing weft threads (25) and/or reinforcing warp threads (26). At least some of the inserted reinforcing threads (25) are shortened reinforcing weft threads (25a) and/or shortened reinforcing warp threads (26a). Their thread length (L) is less than that of the binding weft threads (24) or the binding warp threads (23). The shortened reinforcing thread's (25a), (26a) free ends are located in a respective thread end position (30) or (31). The respective thread length (L) and the respective thread end positions (30), (31) of a shortened reinforcing thread (25a), (26a) in the two-dimensional fabric (20) are predetermined based on the three-dimensional shape of the composite part to be produced to reduce cutting waste when producing preforms and cutting effort.
摘要:
A gripper head of a weaving machine has a clamping device for clamping a band-shaped weft material to be inserted into a loom shed of the weaving machine. The clamping device includes a stationary clamping jaw and a movable clamping jaw that is loaded by a spring and movable about a rotation axis. Each clamping jaw respectively has a clamping surface. The movable clamping jaw is actuatable by a control device to open the clamping device. The gripper head includes a frame, and the clamping surfaces are arranged essentially outside of the frame, but the spring and the rotation axis are arranged inside the frame.
摘要:
A method and means are disclosed for measured control of tape-like warps for shedding and taking-up operations when producing woven materials comprising tape-like warps and wefts. According to this invention, a displaceable contact surface of the warp control device is located between the warp supply source and the shedding device. The warp control device comprises a displaceable member for providing contact surface to displace at least some of the tape-like warps for releasing them in a measured way for shed forming and taking-up operations. Further, the contact surfaces are retracted for enabling shed closing and measured taking-up.
摘要:
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.
摘要:
A textile product (1) comprising individual elements (4) interconnected by a textile technique, characterised in that the interconnected individual elements (4) hold at least one decorative or functional element (2, 2′, 2″, 12, 12′, 22) between each other, e.g. by braiding in or braiding around.
摘要:
A tetraxial fabric is obtained using warp yarns, weft yarns, first bias yarns and second bias yarns. The warp yarns alternate to the weft yarns and the first bias yarns are overlaid by the second bias yarns, in addition the first bias yarns cross the second bias yarns at the crossover points of the warp yarns with the weft yarns. The invention includes also a machine to manufacture the said tetraxial fabric.
摘要:
A protection product made of (i) a woven fabric woven with a high-performance fiber, in which the opening rate of thread-opening treatment is 0 to 5%, and the width of a thread constituting the woven fabric is 10-fold or more relative to the thread thickness, (ii) a woven fabric in which the cross-sectional shape of a thread constituting the woven fabric is thinner on an edge side of both ends as compared with an intermediate part in the width direction, or (iii) a woven fabric woven with a twistless high-performance fiber having a fineness of 200 to 15,000 dtex, in which the ratio of the thread width to the thread thickness of at least one of a warp and a weft is 10 to 100, and the opening rate is 0 to 5%.
摘要:
The present invention provides a multi-wefts inserting weaving machine, comprising a block arraying device comprising an upper plate and a lower plate which face each other and are movable upward and downward; and a plural number of unit blocks attached to the internal facing sides of the upper plate and the lower plate of the block arraying device through combining grooves, wherein the unit blocks include two grooves. Accordingly, a lattice woven structure can be easily woven from heavy-duty materials by the present multi-wefts inserting weaving machine.
