Patent ID: 7861654

Claim:
A cylinder of a printing press comprising: A cylinder outer surface, said cylinder outer surface being subdivided axially into multiple sections arranged side by side; a channel extending in said cylinder, in its axial direction, and below said cylinder surface; at least one retaining device located in said channel to exert a retaining force on at least one end of a packing positioned or to be positioned on said outer surface of said cylinder; at least one control means in said channel, said at least one control means, in its actuated operating state, exerting a counteracting force opposing said retaining force exerted by said at least one retaining device on said at least one end of said packing positioned or to be positioned on said outer surface of said cylinder; means for adjusting a counteracting said force exerted by said at least one control means to a counteracting force value that is different from its minimum value or its maximum value; a plurality of said retaining devices arranged side by side in said channel in at least a specific one of said multiple sections; means segmenting an action of said at least one control means with respect to said plurality of said retaining devices arranged side by side in said at least a specific one of said multiple sections and which are active for said at least a specific one of said multiple sections, such that one of, when said control means is actuated, it acts on only a partial number of said plurality of said retaining devices arranged side by side in said channel and assigned to said at least a specific one of said multiple sections and/or such that, at least with respect to a partial number of said plurality of said retaining devices arranged side by side in said channel and assigned to said at least a specific one of said multiple sections, an adjustment path of said control means assigned to said at least a specific one of said plurality of said retaining devices arranged side by side in said channel and assigned to said at least one specific one of said multiple sections is limited by at least one stop for limiting said adjustment path wherein, the respective forces exerted by the at least one control means on at least two different ones of said retaining devices arranged in said at least a specific one of said multiple sections are different from one another in terms of their respective value.
