ABSTRACT:
A device for longitudinally cutting web material, especially paper and cardboard webs with at least one rotating circular knife pair consisting of a freely rotating point knife that enters the material during the cutting process and a pot knife that rests on a power-rotated hub element. To reliably preserve, with simple means, an initial basic or zero adjustment subsequent to regrinding or replacement of the pot knife, the cutting surface of the pot knife rests axially against a contact surface that is stationary in relation to the hub element.
