Abstract: A cutting device for a cutting machine for use in the corrugated box industry is disclosed. Cooperating rollers or heads are positioned on opposed rotatable shafts. The heads are disposed for cutting or scoring material passed through the heads. A hub assembly is connected to each of the heads for releasably securing the heads to the shaft. The hub assembly is resiliently biased in a manner to secure the rollers on the shaft. A rotatable cam is positioned adjacent the hub assembly. The rotatable cam is rotatable to engage and move the hub assembly in a manner whereby the hub assembly disengages from the shaft and allows the heads to be moved along the shaft to a new position.
