Abstract: A separation apparatus for fiber webs (6) with parallelized fiber positions wound on a processing drum (4) includes an arm (1) rocking relative to the processing drum, the arm carrying a separation comb (13). The arm and its separation comb (13) are mounted for movement along and controlled by the shape of a separation cam (3) implementing the separation of the fiber web (6) wound on the processing drum (4) at a specified site and the unwinding of the separated fiber web from the processing drum (4) by the free end of the fiber web (6) along a generatrix of the surface of the processing drum (4).
