  • a tear-off segment was delivered to a subsequent roller pair, where it is connected or soldered to the end of an already formed fleece.
  • the pair of rollers is driven by a pilgrim step movement.
  • the length of the fiber tuft projecting beyond the clamping point of the tongs increases by the amount supplied, which is available for the subsequent combing operation in the event of subsequently closed tongs.
  • the combed out end of the tuft is transferred with the tongs open again under the action of the tear-off segment into the nip between the tear-off roller and the departure segment. All the fibers then captured by the nip are removed from the present tuft. Since the pliers and the nip of the tear-off roller have a constant spacing in this embodiment, the end of the tuft is abruptly fed to the nip of a tear-off roller.
  • this guide element is permanently installed and is limited in connection with a pivotally mounted to the Abreisszylindern pliers to a change in the Kämmlingsanteils at a constant Ecartement.
  • the length of the combed fiber tuft projecting beyond the nip point of the tongs remains the same for the subsequent tearing off and soldering operation.
  • the aim is to keep the percentage of combed material as low as possible, provided that a high quality of the combing machine belt can be achieved.
  • the demand for high productivity exists.
  • the lower pliers plate and the detaching roller during a comb play stored at a constant distance and at least one means is provided, which, seen in the conveying direction of the fiber mass, behind the feeding transverse movably mounted to the underside of the fiber mass and connected to a driven adjusting means, via which the means during a comb play periodically produces a change in length of the guide track for the fiber mass within the nipper unit.
  • this additional means which changes the path length of the fiber material during a comb play, it is possible to influence or to determine the length of the end of the fiber material protruding from the forceps.
  • the means is arranged inside the nipper unit.

  • the drive of the means for adjusting the means is connected to a controller.
  • the top comb is connected to drive means and is movably mounted in the direction of the payout roller. This makes it possible that the feeding process can be carried out by the feeding means during the tearing off, wherein the fixing comb moves towards the tear-off roller. As a result, there is no material compression in the area behind the fixed comb set, since this also moves in the direction of the material feed.
