  • the rear ends of fibers that have left the pliers can be supported during the tearing, so that such No longer hang fibers down and can run uncombed under the fixed comb.
  • the fiber support element can stand in its end position between the fixed comb and the tear-off cylinders or on the other side of the fixed comb.
  • it can also advantageously be yours to guide the end of the previously formed comb-pulling fleece, which comes out of the clamping line of the latter by a brief reverse rotation of the tear-off cylinders, downward on the tear-off cylinder, so that this end lifts less from the tear-off cylinder.
  • the combing machine according to the invention additionally contains a clamping element which interacts with the fiber support element in its end position. This slightly compresses and brakes the fiber beard, which is pulled through the fixed comb when it is torn off, which further improves the separation of nits and impurities.
  • the fiber support element and the clamping element also serve directly as a nip wiper.
  • FIG. 1 schematically shows a vertical section through parts of a combing head of a combing machine according to a first embodiment of the invention
  • FIG. 2; 3 and 4 each in a view corresponding to FIG. 1, a second, a third and a fourth embodiment of the invention and
