Abstract
A groove for receiving opposite end edges of an object, like a printing plate that extends around a printing cylinder, is formed in a printing cylinder adjacent the outer circumferential surface thereof to extend from an axially extending anchor-shaft hole to the outer circumferential surface of the cylinder body. One wall surface of the groove intersects, at an acute angle, a tangent plane passing through a line of intersection between the wall surface and the outer circumferential surface of the printing cylinder, thereby forming an edge together with the circumferential surface of the printing cylinder. When an anchor shaft inserted into the anchor-shaft hole is rotated by means of elastic force, pins studded into a cutaway surface of the anchor-shaft enter anchor holes formed in an end edge portion of the object and secure the end edge portion within the groove. Thus, the object is attached to the printing cylinder.
