Definitions

  • the invention relates to a loom for producing a leno fabric according to the preamble of patent claim 1.
  • a device for controlling the warp threads in producing a leno fabric in a textile machine is known.
  • the device is preferably part of a weaving machine consisting of a batten carrying a known reed.
  • a needle carrier On the warp side before the reed above the weaving plane, which is determined by the position of the binding point, a needle carrier is positioned with a plurality of needles having a needle eye.
  • the needle carrier is operatively connected by means which translate the same together with the first warp threads (leno threads) into an oscillating vertical movement to the weaving plane for shedding and shedding.
  • a first shaft frame driven vertically to the weaving plane is arranged, which has approximately in the weaving plane a bar with a plurality of arranged in series, obliquely running slots. In each of these slots, a warp thread (guide thread) is guided, whereby the warp threads in oscillating vertical movement of the heald an oscillating transverse movement is imposed.
  • a second shaft frame driven vertically to the weaving plane is provided, which has approximately in the weaving plane a bar with a transverse and parallel to the weaving plane formed slot. In this slot, the warp threads (Steherfäden) are guided.
  • a third, vertically oscillating driven shaft frame is equipped with a pair of compensation rollers, which are arranged umexcellent movable in relation to the shaft frame of the third weaving shank, for example via a fixedly connected to a shaft drive.
  • a further disadvantage is that the device requires several drives, namely a first drive for the shaft frame, a second drive for the needle bar and a third drive for the compensation rollers.
  • a loom according to the US-A-1 776 102 on which corresponds to the preamble of claim 1 of the application.
  • several drive-connected means for guiding the ground threads are provided.
  • These first drive-connected means can independently perform horizontal oscillating movements.
  • each of the first means is designed like a frame and slidably movable in guide grooves.
  • To drive the frame-like first means are attached to these ropes, which are guided over pulleys and connected to unspecified drives below the weaving level.
  • To reset the frame-like first means in their initial position serve fferenzugfedern.
  • a second frame-like means is provided, which oscillates in the vertical direction and has a plurality of downwardly directed needles through the eyelets each a leno thread runs therethrough.
  • a WnkelgestShe consisting of several members is provided, which takes up a considerable space above the weaving plane.
  • the angle linkage is driven by a crank drive, which is located below the weaving plane. At the angle linkage additional arms are articulated, where there is a serving as Fadenumlenkelement cylindrical rod.
  • the known loom according to the US-A-1 776 102 thus has a very complicated, complex and much space-requiring structure; In addition, the stayer and leno threads from above for the weaver are difficult to reach.
  • Another disadvantage is that a plurality of independently operating drives for moving the first and second means are required.
  • the first drive-connected means which serves to guide the ground threads, has at least one guide means for guiding the leno threads, so that the leno threads are guided through the first drive-connected means.
  • the yarn deflecting element for the leno threads is attached to the second drive-connected means, and the first and second means are arranged on the warp side of the reed below the weaving plane.

  • the second means for guiding and deflecting the leno threads can advantageously consist of a needle bar with a plurality of arranged in a row needles with eyelet and arranged adjacent to the needle bar Fadenumlenkelement.
  • the first and second means may extend across the weaving width and are operatively connected to the common drive which oscillates the first means horizontally to the weaving plane and which oscillates the second means vertically to the weaving plane.
  • the first means part of a u-frame-like, upwardly open structure, with a first leg, at the free end of the leno thread guide is arranged.
  • the guide bar is arranged with a plurality of axially parallel passageways for the ground threads.
  • a frame is positioned as a support for the needle bar and for the deflecting vertically displaceable. The vertical displaceability of this frame member can be done for example in sliding guides, which are present on the inner surfaces of the legs of the u-frame-like structure or formed by this.
  • the frame-shaped support member is equipped at its the needle bar and the deflecting remote end with a plurality of connection means with which length adjustable connecting rods for producing a drive connection between the frame-like structure and the drive are present.
  • the frame-like structure has at the end remote from the leno thread guide at least one connection means for producing a drive connection to the drive.
  • the drive connection is made via adjustable length rods.
  • the first means which consists of a first frame-like structure, at its lying above the weaving plane free end a bar with a plurality of axis-parallel standing thread passages is arranged, wherein the first frame-like structure with a drive is operatively connected to perform a horizontal oscillating movement
  • the second means consists of a second frame-like structure in the manner of a heald, with the above the weaving plane, a support member for a needle bar with a plurality of serially connected needles and to which there is further provided in the area of the needle bar a means deflecting the leno threads, the second form being operatively connected to a drive for performing a vertically oscillating movement.
