A rotatable cutting knife for use in a machine for slitting a moving web of metal foil, the cutting knife cooperating with a driven backup knife to slit the foil by a shearing action. The cutting knife has a concave configuration and is supported by a structure affording adjustments of the cutting knife with respect to the backup knife, thereby reducing the overlaping of the knives required to shear a particular foil and minimizing the possibility of the cutting knife overriding the backup knife. |
