ABSTRACT:
An air bearing slitter wherein the slitter disc is mounted on a hub that is freely rotatable and axially movable relative to a shaft on an air bearing. This arrangement has been found to improve the slitter knife life between sharpenings and to permit the use of tungsten carbide coated slitters for slitting paper.
