Abstract
A rotary cutting apparatus comprising a frame and a die roll defining a first longitudinal axis and comprising a cutting member. The die roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis. The rotary cutting apparatus further comprises a bearer ring connected with the die roll and an anvil roll defining a second longitudinal axis and comprising an outer radial surface. The anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis. The bearer ring of the die roll is in contact with the outer radial surface. The anvil roll may be supported by at least one cam follower. The anvil roll may be axially removable from the frame via lateral translation along the second longitudinal axis.
Claims20
A rotary cutting apparatus, the apparatus comprising:
- a frame;
- 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 defining a second longitudinal axis and having first and second ends, the anvil roll having an outer circumferential surface, wherein the anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis, the anvil roll 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;
- 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.
A rotary cutting apparatus, the apparatus comprising:
- a frame;
- 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 defining a second longitudinal axis and comprising an outer circumferential surface, wherein the anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis, the anvil roll 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;
- and
- a cam follower having a cam follower axis, wherein the cam follower is in supporting contact with the anvil roll and configured to rotate about the cam follower axis when the anvil roll rotates.
A method of cutting a web of material, comprising the steps of:
- advancing a web of material in a machine direction directly from a first conveyer into a nip of a rotary cutting apparatus;
- rotating a die roll, the 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 a frame and configured to rotate about the first longitudinal axis;
- rotating an anvil roll, the anvil roll defining a second longitudinal axis and comprising an outer circumferential surface, wherein the anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis, the anvil roll positioned relative to the die roll 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 is at least twice the maximum diameter of the anvil roll;
- supporting the anvil roll with a rotatable cam follower, the rotatable cam follower in frictional contact with the anvil roll;
- cutting at least a portion of the web of material with the cutting member;
- and
- advancing the web of material in a machine direction directly from the nip to a second conveyor.
