Printing cylinder for offset printing machine, has several cups each having conical surface which partially bears against adjacent cup to form connection between the cups

摘要

The printing cylinder (10) has several cups (18,18a,18b,18c) for forming an inner structure (17) for supporting an outer layer (56) on exterior (14) of the printing cylinder. The cups have central disks and radially outer edges (24,24a,24b,24c) defining cylindrical surfaces. Each cup has a conical surface which partially bears against an adjacent cup to form connection between the cups. An independent claim is included for method for producing printing cylinder or printing sleeve.
