Abstract

The perforating or cutting device comprises: a support rotating around a rotation axis and at least one rotary blade, carried by the rotary support; and a stationary support, on which there is mounted at least one stationary counter-blade arranged to cooperate with the rotary blade. During the rotation of the rotary support, the rotary blade cooperates with the stationary blade to perforate or cut a web material supplied in a machine direction between the rotary support and the stationary support. The stationary counter-blade comprises a cutting edge having a variable inclination with respect to the machine direction, to generate, cooperating with the cutting edge of the rotary blade, a perforation or cutting line with a non-straight shape on the web material.
