The web sepn. device uses a reciprocating cutter (6) with at least one cutting edge (15) cooperating with a pair of cutters (7,8) lying on the opposite side of the transported material web. The cutters (7,8) can slide perpendicular to the sepn. plane against the force of a return spring, their cutting edges (32,33) exhibiting an angle of between 5 seconds and 1 degree with the sepn. plane. ADVANTAGE - Friction and wear are reduced to min.
