Problems solved by technology

[0003] The prior art has the disadvantage that, at high rotational speeds of the drum, there is a risk that the stop bolt comes out of its stop hole with a centering tip due to centrifugal force
However, the operator thus has to use excessive force against the action of the helical spring when releasing the stop

Embodiment Construction

[0033] Figure 16 The cylinder 23 of the printing press is shown. Cylinder 23 is the plate cylinder (plattenzylinder) of the nozzle train of the printing press. A first drum lining 1 and a second drum lining 2 are arranged on the drum 23 . The second cylinder lining 2 is a printing plate for varnish in flexographic printing. The first drum liner 1 is located below the second drum liner 2 and forms the underlayment for the second drum liner 2 . The drum 23 has a drum channel 24 in which the clamping rail 3 is arranged. The drum tunnel 24 is a tensioning tunnel, in which tensioning mechanisms are provided for tensioning the second drum lining 2 , but these tensioning mechanisms are not shown together in the figures. That end of the first roller lining 1 protruding into the roller channel 24 is clamped in the clamping rail 3 . The first cylinder liner 1 may comprise a plurality of layers (for example layers of paper).

Abstract

The invention relates to a cylinder of a printing machine, comprising: a first cylinder lining; a clamping rail (3), used to fix and maintain the first cylinder lining; a supporting device, used for loading and unloading one end of the clamping rail; Wherein, the supporting device has: a lock piece (4), used for radially securing the clamp rail (3); and a cam (5), used for axially moving the clamp rail (3), wherein the lock piece (4) and The cams (5) have the same geometrical axis of oscillation (7).

Description

technical field [0001] The invention relates to a cylinder of a printing machine, comprising: a cylinder lining, a clamping rail for fixing and maintaining the cylinder lining, and a supporting device for loading and unloading the end of the clamping rail. Background technique [0002] Such a roller is described in document DE 101 27 133 B4. In prior art rollers, quick connections designed as locking devices are arranged on the clamping rails and on the roller. The quick connect structure includes two stop bolts that are axially aligned and mounted on opposite ends of the clip rail. One stop bolt is provided with a centering tip, and the other stop bolt is fitted with a helical spring which acts on the other stop bolt (eg a spring pin). In the locked state of the clamping rail, the two locking bolts are located in the locking holes of the drum. The helical spring, which is prestressed here, holds the locking screw with its centering tip in the locking hole assigned to it ...
