A housing of a switchgear cabinet for a printing machine, with housing elements formed of electrically conductive material having an electrically insulating surface layer, includes at least one door, one body and one electrically conductive elastic seal disposed therebetween, respective mutually allocated elements of the housing elements having corresponding electrically conductive contact locations at electrically conductive strip material connected to the conductive material of the housing elements; each of the contact locations being covered by a protective layer which is removable during assembly of the cabinet, for the purpose of electrically conductively connecting the housing elements and the seal.

Shielded switchgear cabinet housing

A quick-action clamping device for fastening a printing plate on a plate cylinder in a printing machine by a fixed clamping bar and a displaceable clamping bar which are able to be brought into a clamping position and a plate-changing position, respectively, includes a spring device for resiliently pressing the displaceable clamping bar into the clamping position with a holding force for clamping a printing plate between the displaceable clamping bar and the fixed clamping bar, and at least one re-set element for returning the displaceable clamping bar to the plate-changing position against the holding force.

Quick-action clamping device

A clamping and tensioning device for clamping a printing plate on a cylinder of a printing machine includes a tensioning bar and a clamping bar having substantially radially extending, mutually opposing clamping surfaces for gripping therebetween a bent end of a printing plate, the tensioning bar being formed as a pivotal double lever, tension spring devices engageable with the tensioning bar for applying a tensioning force thereto in a tensioning direction, adjusting devices engageable with the tensioning bar and actuatable for pivoting the tensioning bar against the tensioning force applied by the tension spring devices, the clamping bar being formed as a pivotal double lever connected to the tensioning bar, clamping spring devices engaging with the clamping bar for pressing the clamping surface of the clamping bar against the corresponding clamping surface of the tensioning bar with a clamping force for holding a printing plate therebetween, the clamping bar being further formed with a holding element, a fixed stop cooperatively engageable by the holding element for pivoting the clamping bar against the force of the clamping spring devices when the adjusting devices are actuated.
