20100326302 | PRINTING CYLINDER OR PRINTING CYLINDER SLEEVE AND METHOD FOR PRODUCING IT - A method for producing a printing cylinder or a printing cylinder sleeve includes providing a plurality of cylindrical discs with an essentially cylindrical outside surface and respectively one central opening for positioning the cylindrical discs around a core, and machining the essentially cylindrical outside surfaces so that the cylindrical discs form a printing cylinder surface when mounted on the core. Prior to positioning the cylindrical discs around the core, the method includes machining at least one of the cylindrical discs to form at least one contact surface. The contact surface is machined precisely so that during the installation of the respective cylindrical disc around the core, the contact surface comes to rest parallel against a complementary formed surface of an adjacent element of the printing cylinder or printing cylinder sleeve. The method further includes positioning the cylindrical discs around the core and alternately joining the cylindrical discs. | 12-30-2010 |
20100199868 | PRINTING CYLINDER OR PRINTING SLEEVE, CUP AND METHOD FOR PRODUCING A PRINTING CYLINDER OR PRINTING SLEEVE - A printing cylinder for a printing machine or printing sleeve for forming a printing cylinder that includes a plurality of cups for forming a supporting inner structure of the printing cylinder or printing sleeve. Each cup includes a central disc, a radially outer edge, and a first conical surface part. The first conical surface part of one cup at least partially bears against an adjacent cup in order to form a connection between the one cup and the adjacent cup. The radially outer edges of the plurality of cups together define a substantially cylindrical surface. | 08-12-2010 |
20100192790 | Printing Cylinder or Printing Sleeve with Insert - A printing cylinder or printing sleeve including an internal structure that is at least partially open and the internal structure defines a hollow space. A substantially liquid-tight cylindrical outer layer surrounds the internal structure and a coupling device couples a plate to the printing cylinder or printing sleeve. The coupling device is at least partially positioned in, on, or under the outer layer. An insert is supported by the internal structure and is arranged at least partially around or under the coupling device. The insert is constructed to impart strength to the coupling device. | 08-05-2010 |
