Definitions

  • the present invention relates to a shedding device for weaving machines, the stranded warp threads between a top shed position and a lower shed are back and forth, for the respective provision of the strands in the lower shed on each strand a, in a sheathing sleeve axially displaceable tension spring acts, which is attached to a Niederzugêt or Niederzugstab a Niederzugrahmens and wherein the front side of the axially relative to the respective strand movable sleeve, a device for preventing dust and lint formation on the return spring is arranged.
  • Essential shedding devices are, among others, the so-called Jacqard machines in which two boards are connected via a common pulley at the lower end, the boards depending on the control, for example via magnetic means, with two constantly counter-rotating lifting knives are coupled, causing the example attached to the pulley Strand and thus the respective warp thread a controlled lifting movement between an upper shed position and a lower shed position is issued.
  • Jacqard machines in which two boards are connected via a common pulley at the lower end, the boards depending on the control, for example via magnetic means, with two constantly counter-rotating lifting knives are coupled, causing the example attached to the pulley Strand and thus the respective warp thread a controlled lifting movement between an upper shed position and a lower shed position is issued.
  • Object of the present invention is to provide a way that effectively prevents any dust and lint formation on the return springs so that downtime due to such disturbances virtually eliminated.
  • the device for preventing dust precipitation and linting on the return spring surrounding the strand in question and at this hermetically sealing circumferentially fitting, non-displaceably connected to the relevant end face of the sleeve, is effective on the strand as a dust and Flusenabstreifer lip seal.
  • the lip seal is replaceable in a frontally arranged in the sleeve cage or directly frontally of the sleeve is inserted into this.
  • the lip seal is in this case preferably a micro lip seal.
  • the shed device for looms according to FIG. 1 here is a so-called open shed jacquard machine, in which two boards 1 u. 2 are connected via a common pulley 3 at the lower end, the boards depending on the control, here on the magnetic means 4, with two constantly counter-rotating lifting blades 5 u. 6 can be coupled, whereby the attached to the pulley 3 strand 7 and thus the respective warp 8 a controlled lifting movement between an upper shed position (left side Fig. 1) and a lower shed position (right side) is granted.
  • each, acting on a strand 7 tension spring 9 is surrounded by a sheathing sleeve 11, in which the return spring in question moves axially ( Figure 2).
  • an apparatus 13 for preventing dust precipitation and lint formation on the return spring 9 is arranged on the end face of the sleeve 11, which is movable axially relative to the relevant strand 7 (FIG. 3).
  • the device 13 for preventing dust precipitation and linting is arranged frontally where the sleeve 11 moves axially relative to the respective strand 7.
  • Fig. 3 shows in more detail, the device 13 for preventing Dust precipitation and linting on the return spring surrounding the respective strand 7 or hook or connecting means and at this (m) circumferentially hermetically sealed, non-slip associated with the respective end face of the sleeve lip seal.
  • the lip seal on the strand and / or on the hook or connecting means as dust and Flusenabstreifer effective.
  • the lip seal 14 is preferably used interchangeably in a frontally arranged in the sleeve 11 cage 17.
  • the cage on the front side an annular shoulder 16 which engages behind a spreizringieri Abragung 18 on the body of the lip seal.
  • a device according to the invention for preventing dust precipitation and lint formation on the return spring can also be provided simultaneously on both end faces of the relevant sleeve.
  • the lip seal may preferably be a micro-lip seal, which preferably consists of polyurethane o. The like., Which may be arranged without a cage directly on the front side of the sleeve.
