Abstract
A printing plate is only guided by and wound around peripheral surfaces of cylinders. The cylinders are disposed along an axis of a rotating shaft at predetermined intervals, and support the entire printing plate with substantially equal balance. The printing plate has a degree of firmness, and thus, the printing plate can hold itself in a substantially cylindrical shape even if it is merely rolled in the air. Therefore, the whole printing plate can be accurately wound and held onto a peripheral locus of a predetermined radius coaxial with the rotating shaft merely by disposing guide members as auxiliary guides for positioning and winding parts of the printing plate.
