Abstract
Abstract A pair of cooperating circular slitter blades are adjusted by locking a first of these blades in a selected axial position on its drive shaft and moving the second of these blades along its drive shaft into engagement with the first blade. Prior to locking the second blade in an axial position on its drive shaft, the latter together with the second blade are turned slowly through at least one revolution for axial runout of the second blade. Thereafter the second blade is locked in axial position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
119 words
A method for setting the operative relationship between cooperating first and second circular slitting blades mounted on respective first and second parallel rotatable shafts; said method comprising the steps of locking the first blade in a selected operative axial position on the first shaft and moving the second blade into operative side-to-side engagement with the first blade; thereafter, and prior to locking said second blade in axial position on said second shaft, rotating said shafts and blades thereon slowly through at least one revolution; and thereafter locking said second blade in the axial runout position assumed by said second blade on said second shaft resulting from the aforesaid step of rotating said shafts slowly through at least one revolution.
Claim 2
Independent Claim
119 words
A method for setting the operative relationship between cooperating first and second circular slitting blades mounted on respective first and second parallel rotatable shafts; said method comprising the steps of locking the first blade in a selected operative axial position on the first shaft and moving the second blade into operative side-to-side engagement with the first blade; thereafter, and prior to locking said second blade in axial position on said second shaft, rotating said shafts and blades thereon slowly through at least one revolution; and thereafter locking said second blade in the axial runout position assumed by said second blade on said second shaft resulting from the aforesaid step of rotating said shafts slowly through at least one revolution.
Claim 3
Dependent Claim
113 words
A method as set forth in claim 1 in which there is a third slitting blade which is locked in a selected operative axial position on the first shaft and a fourth slitting blade on said second shaft which is moved into operative side-to-side engagement with said third blade; thereafter, and prior to locking said second and fourth blades in operative positions on said second shaft; rotating said shafts and blades thereon slowly through at least one revolution; and thereafter locking said fourth blade in the axial runout position assumed by said fourth blade on said second shaft resulting from the aforesaid step of rotating said shafts slowly through at least one revolution.
