ABSTRACT:
An apparatus for cutting, including an anvil cylinder which may have a plurality of cut rubbers strips affixed around the anvil cylinder and a cut cylinder which is mounted for rotation about an eccentric axis. Two knife boxes may be mounted on the cut cylinder, each knife box having a knife and cheekwood for securing the knife to the cut cylinder. A paper tape guides the material to be cut between the cut cylinder and the anvil cylinder. When one knife box degrades, a knife sleeve on the cut cylinder can be indexed so that the other knife box takes the place of the degraded knife box. When a cut rubber strip degrades, the anvil cylinder can be indexed so that another cut rubber strip takes the place of the degraded cut rubber strap. Either of these functions can occur while the apparatus is still running. The anvil cylinder can also use a cut rubber sleeve.
