Definitions

  • the invention relates to a width loom with a number of shaft frames, each of which is connected by means of a number of Schaftzughebel and shank connecting rods with a Schaftzugstange to whose drive a drive device is provided, the Schaftzughebel are housed with the associated shaft connecting rods in weaving machine sections.
  • Such width looms for example, have a weaving width of 8 to 30 m.
  • the shank pull rods are correspondingly long and combined with lateral rod extensions which connect the shank pull rods to the drive device laterally provided on the loom.
  • the drive device may be provided on one side of the wide loom.
  • Such training requires correspondingly long connecting rods ie lateral rod extensions in which unwanted bends are often unavoidable.
  • looms are also known in which a driving device for the shaft frame is provided on each of the two sides facing away from the wide weaving machine.
  • the connecting rods ie the lateral rod extensions between the drive devices and the shaft tie rods, are also very long, so that even with such a design undesired bending out of the connecting rods is often unavoidable.
  • a weaving machine which has a drive device on one side, wherein the connecting rods are connected at their ends remote from the shaft frame each with an eccentric drive.
  • the eccentric drives are spaced apart from each other in the width direction of the weaving machine and arranged in pairs opposite one another in order to reduce the length of the connecting rods to the Schaftzugstangen.
  • the connecting rods in a wide loom with corresponding shaft frame dimensions of 8 to 30 m are very long, so that unwanted bends are hardly avoidable.
  • a weaving machine with a driving device provided on one side of the width loom and spaced apart in the width direction and having opposite drive means each connected to a connecting rod is known in the art, for example JP 10130986 A known.
  • the connecting rods also applies to this latter loom, the above for EP 1 260 620 A1 made statements accordingly.
  • This known weaving machine has a number of shaft frames, each of which is connected by means of a number of Schaftzughebel and shaft connecting rods with a Schaftzugstange.
  • a drive device is provided to drive the Schaftzugstangen.
  • the Schaftzugstangen are connected to the drive device forming drive means, which are provided laterally adjacent to the shaft frame.
  • the DE 101 11 017 A1 discloses a weaving machine in which the shaft frames may, for example, have a width of 3 m and more.
  • the shaft frames are not connected by means of shaft pull lever and shaft connecting rods with an associated Schaftzugstange, but there are referred to as push-pull rods shaft connecting rods are not hinged to Schaftzughebein, but at a suitable point fixed in its direction of rotation oscillating reversible rotor of an electrically controllable motor.
  • a wide weaving machine known, for example, may have a weaving width of 8 m to 30 m.
  • the store drives are angled in this known wide weaving machine, so that they extend underneath the shaft frame.
  • These loading drives are stored in intermediate levels, which serve as loom reinforcement of the weaving machine and subdivide the loom into sections.
  • the section distances can be 1 to 3 meters.
  • the invention has for its object to provide a width loom of the type mentioned above, are avoided in the bends of connecting rods, as described above.
  • the wide weaving machine according to the invention advantageously dispenses with connecting rods connecting the drive rods to the drive devices or reduces the number of lateral drive devices with associated connecting rods corresponding to the number of drive devices arranged in the weaving machine sections, so that unwanted deflections of long connecting rods are avoided.
  • the fact that at least a number of the drive means are housed in the weaving machine sections there is also the advantage that the footprint for the weaving machine is reduced accordingly, because it can be dispensed with lateral drive devices at all or their number of the number housed in the weaving machine sections drive means is substantially reduced accordingly.
  • weaving machine sections can be housed in each case a number of drive means for a corresponding number of shaft frames. This depends on the dimensions of the weaving machine sections defined by the drives of the weaving machine loader.
  • the respective drive device it is possible for the respective drive device to be connected to the associated shaft pull lever.
  • the respective drive device is connected to the associated shaft tie rod.
  • the eccentric device can be provided for adjusting the shaft stroke of the associated shaft frame adjustable.
  • the respective drive means is connected to the associated shifter lever by means of an elastic or articulated train.
  • the respective train may e.g. have a toothed belt.
  • the respective drive device can be connected to the associated shaft pull rod via an elastic or articulated train by means of a driver.
  • This train may also have a toothed belt.
  • the respective drive device can have a controllable drive motor with a gear.
  • This drive motor may be, for example, a servo-controlled motor or the like.
  • the weaving machine according to the invention can have width dimensions of 8 m to 30 m. After at least a number of drive means of the drive device in the defined by the drives of the weaving machine load Weaving machine sections are shifted, the footprint is limited either to the width dimension of the shaft frame or according to the number of laterally remaining, residual drive means only slightly larger than this.
  • a very significant advantage is that the reliability of operation of the weaving machine according to the invention is comparatively large, because bends or buckles of very long connecting rods between the shaft levers and the drive means of a lateral drive device are at least reduced or even excluded.
  • FIG. 1 illustrates schematically in a cutaway front view of an embodiment of the wide loom 10 with a number of shaft frame 12, of which in Figure 1, only one shaft frame 12 is shown cut centrally. The remaining shaft frames are located in a plane parallel to the plane of the drawing of FIG. 1 and are covered by the shaft frame 12 shown in FIG. The same also applies to the Schaftzughebel 14, the shaft connecting rods 16 and the Schaftzugstangen 18th
  • the respective shaft frame 12 is connected by means of a number of Schaftzughebel 14 and shaft connecting rods 16 with an associated Schaftzugstange 18.
  • the shank pull rod 18 extends through weaving machine sections 20 of the loom 10, of which only four weaving machine sections 20 are illustrated in FIG. 1 as a result of the sectional illustration.
  • the weaving machine sections 20 are defined by the drives 21 of a weaving machine loader (not shown) which are spaced apart from one another in the weft direction and by means of which the weft thread is respectively struck against the edge of the goods.
  • FIG. 2 schematically illustrates a design of the loom 10 with a two-sided shank cable, wherein two shank pull rods 18 are illustrated, each with associated shank levers 14, shank connecting rods 16 and shank frame 12 drawn in a cutaway view.
