PURPOSE:To easily realize a twist regulation of a printing plate by providing a regulating screw moving toward an axial center of a plate cylinder at one end of a gripper end side gripping mechanism and an energizing member for always pressing to support a regulating screw to inside a groove at the other end. CONSTITUTION:When a nut 39b of a twist regulating bolt 39 is rotated, the bolt 39 is moved in a direction of an arrow. Simultaneously, both stationary gripping parts 20 of a gripper side plate vice B are simultaneously compressed at a spring 35, and moved against its energizing force in a direction of an arrow. That is, when the vice B is moved to a left side with respect to a plate cylinder 1, an edge of a printing plate 3 is moved in a direction of an arrow to the cylinder 1 at a bolt 9 of a starting end of the plate 3 as a center. Accordingly, the plate 3 is corrected at its position when the edge of the plate 3 is moved by a size relatively deviated at a starting end to the finishing end, and straightly pulled along a circumferential direction of the cylinder 1. On the contrary, when the finishing end of the plate 3 of a vice A is deviated to a left side, the finishing end of the plate 3 of the vice B is deviated to a right side and the entire plate 3 is twisted, a nut 39b of the bolt 39 is reversibly rotated, and hence its twist is regulated. |
