Abstract
A plurality of blades are supported for initially severing a continuous tubular core into a plurality of specialty cores and subsequently slitting a continuous sheet of paper as it is drawn from a bulk roll and wound about the specialty cores. Each blade is replaceably carried by an assembly which is selectively positionable along a bar to provide specialty rolls of coiled paper in predetermined widths. A mandrel upon which the core is carried is provided with a plurality of spaced annular grooves for receiving the cutting edge of each blade.
