First claim
Opening claim text (preview).
What is claimed is: 1. A cutting assembly for separating absorbent articles from continuous webs of absorbent articles, the cutting assembly comprising: a frame; a first cutting roll rotatably positioned on the frame, wherein the first cutting roll comprises a first cutting device; a second cutting roll rotatably positioned on the frame, wherein the second cutting roll comprises a second cutting device; wherein the first cutting roll has a different diameter than the second cutting roll; a drive mechanism configured to rotate the first cutting roll and/or the second cutting roll; and a shifter, wherein the shifter is configured to move the first cutting roll between an online position and an offline position, and wherein the shifter is configured to move the second cutting roll between an offline position and an online position. 2. The cutting assembly of claim 1 , comprising a third cutting roll rotatable positioned on the frame, wherein the third cutting roll comprises a third cutting device, wherein the drive mechanism is configured to rotate the third cutting roll, and wherein the shifter is configured to move the third cutting roll between an offline position and an online position. 3. The cutting assembly of claim 2 , wherein the third cutting roll has a different diameter than the first cutting roll and the second cutting roll. 4. The cutting assembly of claim 2 , wherein the third cutting roll has the same diameter as the first cutting roll or the second cutting roll. 5. The cutting assembly of claim 2 , comprising a fourth cutting roll rotatably positioned on the frame, wherein the drive mechanism is configured to rotate the fourth cutting roll, wherein the fourth cutting roll comprises a fourth cutting device, and wherein the shifter is configured to move the fourth cutting roll between an offline position and an online position. 6. The cutting assembly of claim 5 , wherein the fourth cutting roll has a different diameter as the first cutting roll, the second cutting roll, and/or the third cutting roll. 7. The cutting assembly of claim 1 , wherein the first cutting roll comprises a first bearing ring and a second bearing ring, wherein a first bearing member is positioned intermediate the first bearing ring and a first portion of the first cutting roll, and wherein a second bearing member is positioned intermediate the second bearing ring and a second portion of the first cutting roll. 8. A cutting assembly for separating absorbent articles from continuous webs of absorbent articles, the cutting assembly comprising: a frame; a first cutting roll rotatably positioned on the frame, wherein the first cutting roll comprises a first cutting device; a second cutting roll rotatably positioned on the frame, wherein the second cutting roll comprises a second cutting device; a third cutting roll rotatable positioned on the frame, wherein the third cutting roll comprises a third cutting device; wherein the first cutting roll has a different diameter than the second cutting roll; a drive mechanism configured to rotate the first cutting roll, the second cutting roll, and/or the third cutting roll; and a shifter, wherein the shifter is configured to move the first cutting roll between an online position and an offline position, wherein the shifter is configured to move the second cutting roll between the offline position and an online position, and wherein the shifter is configured to move the third cutting roll between an offline position and an online position. 9. The cutting assembly of claim 8 , wherein the third cutting roll has a different diameter than the first cutting roll and the second cutting roll. 10. The cutting assembly of claim 8 , wherein the third cutting roll has the same diameter as the first cutting roll or the second cutting roll. 11. The cutting assembly of claim 8 , comprising a fourth cutting roll rotatably positioned on the frame, wherein the drive mechanism is configured to rotate the fourth cutting roll, wherein the fourth cutting roll comprises a fourth cutting device, and wherein the shifter is configured to move the fourth cutting roll between an offline position and an online position. 12. The cutting assembly of claim 11 , wherein the fourth cutting roll has a different diameter as the first cutting roll, the second cutting roll, and/or the third cutting roll. 13. The cutting assembly of claim 8 , wherein the first cutting roll comprises a first bearing ring and a second bearing ring, wherein a first bearing member is positioned intermediate the first bearing ring and a first portion of the first cutting roll, and wherein a second bearing member is positioned intermediate the second bearing ring and a second portion of the first cutting roll. 14. A cutting assembly for separating absorbent articles from continuous webs of absorbent articles, the cutting assembly comprising: a frame; a first cutting roll rotatably positioned on the frame, wherein the first cutting roll comprises a first cutting device; a second cutting roll rotatably positioned on the frame, wherein the second cutting roll comprises a second cutting device; wherein the first cutting roll has a different diameter than the second cutting roll; a drive mechanism configured to rotate the first cutting roll and/or the second cutting roll; and a shifter, wherein the shifter is configured to move the first cutting roll between an online position and an offline position, and wherein the shifter is configured to move the second cutting roll between an offline position and an online position; wherein the first cutting roll comprises a first bearing ring and a second bearing ring, wherein a first bearing member is positioned intermediate the first bearing ring and a first portion of the first cutting roll, and wherein a second bearing member is positioned intermediate the second bearing ring and a second portion of the first cutting roll. 15. The cutting assembly of claim 14 , comprising a third cutting roll rotatable positioned on the frame, wherein the third cutting roll comprises a third cutting device, wherein the drive mechanism is configured to rotate the third cutting roll, and wherein the shifter is configured to move the third cutting roll between an offline position and an online position. 16. The cutting assembly of claim 15 , wherein the third cutting roll has a different diameter than the first cutting roll and the second cutting roll. 17. The cutting assembly of claim 15 , wherein the third cutting roll has the same diameter as the first cutting roll or the second cutting roll. 18. The cutting assembly of claim 15 , comprising a fourth cutting roll rotatably positioned on the frame, wherein the drive mechanism is configured to rotate the fourth cutting roll, wherein the fourth cutting roll comprises a fourth cutting device, and wherein the shifter is configured to move the fourth cutting roll between an offline position and an online position. 19. The cutting assembly of claim 18 , wherein the fourth cutting roll has a different diameter as the first cutting roll, the second cutting roll, and/or the third cutting roll.
