Claim:
1. A rotary cutting apparatus, the apparatus comprising: a frame comprising an opening; a die roll defining a first longitudinal axis and having an outer circumferential portion comprising a cutting member, wherein the outer circumferential portion has a maximum outer diameter, wherein the die roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis; a bearer ring connected with the die roll; an anvil roll having first and second ends, the anvil roll having an outer circumferential surface, wherein the anvil roll is rotatably connected with the frame to define a second longitudinal axis, wherein the anvil roll is rotatable about the second longitudinal axis to cooperate with the die roll to cut material, and wherein the anvil roll is also translatable along the second longitudinal axis, the anvil positioned relative to the die roll such that the bearer ring is in contact with the outer circumferential surface such that the first longitudinal axis is substantially parallel with the second longitudinal axis, wherein the anvil roll has a maximum outer diameter, wherein the maximum outer diameter of the outer circumferential portion of the die roll is at least twice the maximum diameter of the anvil roll; a cam follower having a cam follower axis, wherein the cam follower is in contact with the anvil roll and configured to rotate about the cam follower axis when the anvil roll rotates; and a first bearing block and a second bearing block, the first and second bearing blocks receiving respective first and second ends of the anvil roll, wherein the anvil roll is selectively removable from the frame and the bearing blocks via translation along the second longitudinal axis through the opening in the frame while supporting the anvil roll with the rotatable cam follower.
