1. A device for processing a continuous web of filter material, comprising:
a feed station for feeding a continuous web defining a direction of feed towards a cutting station for cutting the continuous web, according to a cutting length, into individual disc-shaped segments of the continuous web, and a feed station for feeding each of the individual disc-shaped segments obtained by cutting the continuous web;
a first cutting unit comprising an opposing element, which rotates about a first axis of rotation, and a cutting member, which rotates about a third axis of rotation and which acts in conjunction with the opposing element at the cutting station to obtain the individual disc-shaped segments from the continuous web according to the cutting length;
a second cutting unit for cutting the continuous web, located between the feed station for feeding the continuous web and the first cutting unit, and comprising at least one cutting element configured to sever the continuous web across a full width thereof in a direction transverse to the direction of feed of the continuous web;
a drive unit configured to issue a command to move the at least one cutting element from a non-operating position, where the continuous web is fed by the feed station to the first cutting unit through the second cutting unit, to an operating position, where the continuous web is severed by the at least one cutting element to interrupt feeding of the continuous web to the first cutting unit;
wherein the second cutting unit comprises a roller which rotates about a second axis of rotation and which has on an external surface a first portion adapted to define an anvil for the at least one cutting element;
wherein the roller of the second cutting unit has a second portion configured as an inclined surface to guide the continuous web during feeding from the feed station to the first cutting unit.
