The body includes a first orientation element for properly orienting the ring on the sleeve, to enable the ring to be disposed on the sleeve such that the register notch lies in a position suitable for cooperation with the register pin. | 06-24-2010 |
| 20100242759 | PRINTING COUPLE, PRINTING PRESS, AND METHODS FOR OPERATING APRINTING COUPLE - A printing group of a printing press includes at least one forme cylinder that has at least one axially extending opening on the external surface of the cylinder. That at least one axially extending opening forms a channel in the cylinder and in which channel several printing forme end retaining assemblies are provided. These retaining assemblies are provided in the channel on both sides of a center plane which bisects the forme cylinder perpendicularly to its axis of rotation. A first one of these retaining assemblies that adjoins the center plane cooperates with a second retaining assembly, located on the other side of the center plane, to both engage the same printing forme, in a first mode of operation. In a second mode of operation, the first retaining assembly cooperates with a third retaining assembly, that is located further away form the center plane, and on the same side thereof as the first retaining assembly, to engage a second printing forme. | 09-30-2010 |
| 20100288147 | PRINT CYLINDER WITH RUBBER BLANKET FOR A ROTARY OFFSET PRINTING PRESS - An apparatus for a rotary offset printing press includes a print cylinder having a radially inward extending groove and a rubber blanket having a main section coupled to the print cylinder. The rubber blanket includes at least first, second and third layers in the main section. The first layer is a self-adhering layer which faces the print cylinder and is adapted to attach the rubber blanket to the print cylinder. The second and third layers are a support layer and a cover layer, respectively, which both face away from the print cylinder. The rubber blanket has a leading end section, as seen in a production direction of the print cylinder, and a trailing end section, as seen in the production direction of the print cylinder. The end sections directly adjoin the main section and at least the leading end section of the rubber blanket is inserted into the groove of the print cylinder. | 11-18-2010 |

| 20120067235 | METHOD AND APPARATUS FOR SECURING PRINTING FORMS ON A MOUNTABLE SURFACE - A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum, comprising positioning a first portion of the printing form over a first set of pins that are coupled to a surface of the drum. The first portion of the printing form is then stamped onto the first set of pins thereby securing the first portion of the printing form to the drum. A rotatable member having a second set of pins is rotated so that the circumferential distance between the first set of pins and the second set of pins, is about equal to the length of the printing form. The drum is rotated until a second portion of the printing form is positioned above the second set of pins. The second portion of the printing form is then stamped onto the second set of pins. | 03-22-2012 |
| 20140053747 | Printing Assembly - A printing assembly including a clamping annulus having a tiered circumferential end, an axial end and an oppositely axial end, the clamping annulus's axial and oppositely axial ends having outside diameters, the axial end outside diameter having with respect to said oppositely axial end outside diameter an excess dimension defining a guide sleeve receiving space within the clamping annulus; a matching cylinder annularly overlying the clamping annulus; a plurality of magnet recesses, each recess among the plurality of magnet recesses extending radially into the cylinder, and each recess among the plurality of magnet receiving recesses opening radially outwardly from the cylinder's outer surface; and a multiplicity of magnets, each magnet among the multiplicity of magnets being embedded within one of the recesses among the plurality of magnet receiving recesses. | 02-27-2014 |
