Definitions

  • the invention relates to an opening roller for an open-end spinning device according to the preamble of claim 1.
  • opening rollers for open-end spinning machines are known for the purpose the replacement of the set are made in several parts.
  • the set can consist of teeth or needles, which are applied to a clothing carrier are. This is, for example, in the form of a ring which applied to a base body of the opening roller and via a holder is held on the base body.
  • the opening roller runs in an opening roller housing around.
  • a sliver is placed in the opening roller housing are introduced and the fibers separated from it are fed via a fiber feed channel dissipated.
  • Air balance in the opening roller housing plays a decisive role. It is for that required that the gap between the opening roller and opening roller housing are precisely adhered to.
  • the set which is known to be subject to wear and tear, is subject to the conditions do not change in the opening roller housing.
  • DE-A 25 28 485 shows an opening roller in which the ring-shaped clothing carrier non-positively via an elastic element in connection with a Holder for the clothing carrier is held on the base body.
  • the elastic Element is applied by applying an axial force in the radial direction moves so that it rests on the inside of the ring-shaped clothing carrier and fixed it to the opening roller.
  • the holder forms at least partially the front of the opening roller.
  • the width of the opening roller is thereby set that the holder is designed to be adjustable in the axial direction. This is done, for example, by a thread on the base body, on which the Oats are screwed on directly, or by means of fastening elements, e.g. Screws.
  • the elastic element allows that the holder even after the Lying on the elastic element remains axially adjustable until the desired opening roller width is set.
  • Setting the opening roller width is done every time by measuring and adjusting the Delivery depth of the holder each time the set is replaced by the maintenance person. Then the holder must so that it does not adjust itself can, fixed by a securing element on the base body of the opening roller will.
  • the setting of the width of the opening roller can be in the DE-A 25 28 485 shown execution very precisely, the width is independent of the axial extension of the clothing carrier.
