Definitions

  • Jacquard weaving machines have had the problem of dusting down the drawdowns in the lower part of the weaving harness for years. During the weaving process, flight fibers, dust and fiber abrasion settle. These contaminants slide down and become matted. As a result, the pulldowns can rot and tear. Associated with this is an impairment of the quality of the woven product and ultimately the destruction of the weaving harness. This has to be replaced at short intervals - in certain cases every six months - which leads to a breakdown of the machine.
  • the pneumatic cleaning device on a weaving machine described in CH-PS 584 302 also has a blowing device provided with a plurality of blowing nozzles and a suction device.
  • a blowing device provided with a plurality of blowing nozzles and a suction device.
  • compressed air is blown through the shed from below and extracted again above the shed.
  • additional lateral air flows are provided to improve the cleaning effect.
  • air vortices arise, so that some of the dust does not get into the suction device. Above all, however, in the area of the shed with the warp threads that are constantly in motion, the air flow interferes with the weaving process.
  • the object of the invention is now to create a method and a device for keeping the weaving flesh drawdowns of a jacquard weaving machine free of dirt, in which the disadvantages mentioned above are avoided.
  • the method according to the invention has the features stated in the characterizing part of patent claim 1.
  • the inventive device for performing this method is defined in claim 4.
  • the inventive method ensures that the dust falls down from the shed until it is stopped by the air cushion generated.
  • the dust and dirt are kept in suspension by the air cushion and then move to the side, where they are removed, for example, by the ventilation system of the room or by an optionally arranged suction device.
  • the weaving harness pull-down of the machine is denoted by 1.
  • zone 2 soiling occurs in the form of flight fibers, fiber abrasion and dust during the weaving process. This dirt slides down the cables 4 and, if not removed in time, would matt the harness.
  • pull-downs 4 made of elastic synthetic fiber cords are often used, to which the dust particles additionally adhere due to electrostatic forces, which further complicates their removal.
  • Another improvement is to provide the lower part of the urinary cradle 1 with a casing 10 to the in the trains 4 to to better channel air flowing above.
