Abstract
An adjustable cardboard core cutter for precisely cutting cardboard tubes used as cores in steel slitting operations. The core cutter includes an axially fixed main shaft fixed core support plate, and an axially shiftable core support plate. Cores to be cut are clamped to the shiftable plate which axially shifts in response to preset instructions. An axially fixed cutter serves to cut the core into precise widths.
