Abstract
A reusable mandrel for use in a plate cylinder of a printing press. The reusable mandrel includes two semi-cylindrical shells spaced slightly apart to form a tube having two opposing longitudinal slots. Disposed inside the tube is a controller that may be activated in order to selectively adjust the diameter of the tube. The tube is preferably set at an initial diameter so that the tube may incrementally accept plate material from a supply mandrel. Thereafter, the controller may be activated in order to decrease the diameter of the tube so that the tube may be removed from a spool of used plate material.
