Document Type and Number:

Japanese Patent JP3307749

CONSTITUTION: Receptacle components having clamping surfaces disposed oppositely on a shaft for gripping a printing form extends through the printing-form cylinder formed with a cylinder gap. The component can swivel against a force of a tension spring acting in a tensioning direction by at least one adjusting member, and the other component having a retaining element acturable by the one adjusting element against a force of another tension spring. An expansion shaft 5 passing a groove 4 of the cylinder 1 is expanded axially linearly in axial direction through adjusting mechanisms 11, 12, 13 and supported impossibly to swivel on individual clamping members 15 for twisting the shaft in the circumferential direction by a deviating mechanism independently operable to the members 15.
