A cartridge (24) is configured for slitting a mill roll (12) in a slitting machine. The cartridge (24) includes a first shaft (28) mounted in bearings in a pair of endplates (26), with one end of the shaft having a driven yoke for rotation thereof. The first shaft (28) includes a row of first circular blades (36) spaced longitudinally by corresponding first spacers. A second shaft (42) is pivotally mounted in the endplates, and is spaced parallel with the first shaft (28). A dovetail bar (44) is fixedly joined to the second shaft parallel therewith. And, a row of blade holders are mounted along the dovetail bar, with each holder including a second circular blade aligned with a corresponding one of the first blades for cutting in shear a web unwound from the mill roll. The cartridge may be quickly replaced in the slitting machine for each production run thereof for alignment with cores on a corresponding arbor.
