ABSTRACT:
Apparatus for cutting sheet material suitable for use with a card-dispensing business machine is disclosed. The apparatus includes cooperative roller mechanism having side by side cylindrical portions of selected different diameters, which define cutting edges to slit sheet material fed therethrough. The cutting edges are preferably formed by undercutting the ends of the cylindrical roller portions defining the cutting edges, thereby to form sharp cutting surfaces.
