摘要:
A shed forming device for selecting a shed forming apparatus with the assistance of piezoelectric bending elements in a weaving and/or knitting machine of the jacquard type intended for weaving and knitting patterns. The shed forming device includes complementary ascending and descending hooks and complementary ascending and descending blades adapted to cooperate and mutually hook and unhook. Each of the piezoelectric bending elements has a U-shaped clip at a free extremity thereof having one arm (17) that is adapted to slide over a corresponding one of the hooks. Each of the complementary hooks is attached to an elastic bending spring part which can slide up and down along a groove under the action of one of the ascending blades in order to raise a tackle and also a harness cord.

In a double-gripper weaving machine, intended for weaving plain velvet and carpets, a pile feeder and a combined pile warp beam let-off motion are equipped with a computer in order to calculate the necessary pile warp feed of each operating cycle of the weaving machine and use said calculation as a reference value, both functions pile feeder and pile warp beam let-off motion, being performed directly. The pile warp beam let-off motion has a regulating system consisting of a multi-axis control system provided for one or more pile warp beams.

A device is provided for separating and tensioning warp threads in a face-to-face weaving machine of the type used for weaving at least a first fabric and a second fabric that are linked to each other, the first fabric including at least a plurality of first binding warp threads and first tension warp threads and the second fabric including at least a plurality of second binding warp threads and second tension warp threads. The device comprises a first set of rollers for separating the first binding warp threads from the first tension warp threads, a second set of rollers for causing the separated first binding warp threads to cross each other between the rollers in the second set, a third set of rollers, structurally similar to the first set, for separating the second binding warp threads from the second tension warp threads, and a fourth set of rollers, structurally similar to the second set, for causing the separated second binding warp threads to cross each other between the rollers in the fourth set. The first binding warp threads in the first fabric attain substantially the same tension as the second binding warp threads in the second fabric.

A weaving loom with a sley having a defined weaving range, is provided with at least one first and one second sley leg (21; 22), respectively, for supporting the sley (2), the sley legs being arranged in the form of a deformable rectangle with hinge points at (A, B, C, D), and with a knee mechanism (10) for driving the sley (2). The knee mechanism is rotatably connected to the sley leg (21), to the top side thereof, using a connecting rod (6), the sley legs being connected, at their respective base side, to a first and second reed rotary shaft (23; 24), both the reed rotary shafts (23; 24) running mutually parallel and being mounted on a cross girder (4).

A loom reed with integral deflector heald frame is designed to prevent yarns from becoming entangled during the weaving of carpets and/or velvets, in a face-to-face or pile wire weaving loom. The reed includes dents or drop wires wherein at least one drop wire (3) is made up of a staggered or offset front and rear part which are parallel to each other. The offset between the two parts is in the weft insertion direction relative to the front part (8) of the drop wire (3).

A pulley arrangement for a Jacquard machine, in which for at least every two picks, three positions can be created for the warp threads is made up of two pulley elements (14) and (17) hanging above one another and suspended below each set of two complimentary hooks (11), (12). Pulley cord (13) is fixed by each end to one of the hooks (11), (12), with the downward-hanging part running over the top roller (14') of pulley element (14). Pulley cord (15) is suspended from one hook (11) and runs with the downward-hanging part over the top roller (17') of pulley element (17). It is passed upward over the bottom roller (14") and is fixed by the end to fixed and controllable grid (16). Pulley cord (18) is guided over the bottom roller (17") of pulley element (17), fixed by one end to fixed or controllable grid (19) and is connected by the other end to at least one warp thread.
摘要:
A method for the production of non-fraying edges of a double woven fabric on a double-rapier loom, using a double shed crossing device comprising per shed a needle carrier, an oblique slot plate and a positioning device, characterized in that, in case of alternate weft insertion in the upper and the lower shed, a first shed positioning with crossing threads being guided between the stationary needles remains simultaneously for the upper shed and the lower shed over two successive and alternate wefts, with the preparation of the changeover of the crossing thread and the stationary thread for the next shed positioning.
摘要:
A computer reviews card designs for color changes in a fabric pattern that might cause mixed contours in the fabric woven by a Jacquard design. The computer displays problem positions of the card designs that cannot be corrected by correction lift plans and suggests changes to the card designs. When permitted the computer automatically changes the card designs to avoid mixed contours.
摘要:
The present invention relates, on the one hand, to a method for weaving pile fabrics with at least two different pile heights (a, b) in the same pile row, wherein the fabrics comprise weft threads, ground warp threads and pile-warp threads (1, 2), wherein these pile-warp threads are interlaced in the fabric, according to a pattern, in a figure-forming manner or are inwoven in a non-figure-forming manner, and which, when they are figure-forming, form pile with a well-defined pile height. On the other hand, the present invention relates to a device for manufacturing such fabrics.
