ABSTRACT:
Apparatus for slitting sheet material includes a pair of rotatable shafts having cooperating cutting knife assemblies thereon. The knives on one shaft are in the form of axially-spaced knife rings receivable between knife members on the other shaft. The knife rings are elastically deformable axially of the shafts and are spaced-apart a distance slightly greater than the spacing between the knife members to insure the absence of any gaps between the cooperating cutting knives. The knife members are releasably clamped axially on their shaft and are biased apart upon release of the axial clamping force in order to allow positioning of the knife rings between the knife members. Central mounting holes in the knife members increase in size from the axial center thereof toward the opposite ends thereof for allowing limited tilting movement of the knife members relative to the shaft on which they are mounted.
