PURPOSE:To enable a press plate using a paper, a synthetic resin film, or an aluminum sheet as a substrate to be stably fixed to a plate cylinder with a groove fitting type plate bending shaft, by using the plate bending shaft subjected to a frictional force applying processing. CONSTITUTION:The surface of a groove fitting type plate bending shaft 3 is subjected to a knurling processing or a rubber coating processing 6 to have a frictional force. Both ends of a press plate 1 are previously folded by a plate bending device, and a grip part 8 of the press plate 1 is gripped by a grip 5 provided on one side of a plate cylinder 2. Thereafter, the press plate 1 is wound along the surface of the plate cylinder 2 to be loaded by fitting a grip end part 9 thereof into a groove 4 of the plate bending shaft 3. In this manner, because the press plate 1 is bent at a fixed angle at an inlet part of the groove 4 of the plate bending shaft 3, the press plate 1 can be stably fixed to the surface of the plate cylinder even if making use of a paper or a synthetic resin film as a substrate.
