ABSTRACT:
An anvil roll, for use with a rotary cutting or creasing die, has an expandable shell by which the clearance therebetween can readily be varied. The position of the shell surface is controlled by hydraulic pressure, the magnitude of which is determined by the location of an adjustable piston within a suitable cylindrical section of the internal hydraulic system.
