Problems solved by technology

On the other hand, there are also no measures of protection from the first roller
When the operator is carrying out maintenance work on the second cylinder during the printing run, the operator can inadvertently pass through the gap between the tines of the rake and come into contact with the rotating first cylinder, which can lead to serious injury

Embodiment Construction

[0029] Figure 1a and 1b A printing press 1 for offset lithographic printing on sheets is shown in detail. The glazing device 2 of the printing press 1 is shown schematically in this partial view. The glazing device 2 comprises a first cylinder 3 and a second cylinder 4 . The first cylinder 3 is a counter-pressure cylinder which has gripping devices for conveying the sheets. The second cylinder 4 is an application cylinder for applying a coating liquid (varnish) to the conveyed sheet. To this end, a blanket or printing plate is stretched over the second cylinder 4 .

[0030] The second roller 4 is supported on a bearing device which serves as an adjustment device 5 for adjusting the second roller 4 relative to the first roller 3 . The adjustment device 5 is an eccentric sleeve bearing.

[0031] The second roller 4 can be adjusted at a distance relative to the first roller 3 into the first roller position by means of the adjusting device 5 . The first cylinder position is...

Abstract

The invention relates to a printing press comprising a first cylinder with a first gear, a second cylinder with a second gear, the second cylinder and the second gear are adjusted relative to the first cylinder and the first gear from the position of the first cylinder to the second In the drum position adjusting device, the first gear and the second gear mesh with each other in the first drum position, and the first gear and the second gear disengage with each other in the second drum position. The printing machine also includes a rod-shaped or spindle-shaped finger protection device, an adjustable support planar protection part and a transmission mechanism, the protection part is used to protect the first cylinder and / or protect from the influence of the first cylinder, the adjustment device is through the transmission The mechanism is connected with the finger guard so that the finger guard is forced to be adjusted from the first guard position to the second guard position when the second roll is adjusted from the first roll position to the second roll position, and when the second roll is adjusted to the second roll position In the position, the protective member is adjusted between the first roller and the second roller.

Description

technical field [0001] The invention relates to a printing machine comprising a first cylinder with a first gear, a second cylinder with a first gear, and a mechanism for moving the second cylinder and the second gear from the first cylinder relative to the first cylinder and the first gear. Adjusting means for position adjustment to a second drum position in which the first and second gears mesh with each other and in which the first and second gears disengage from each other. Background technique [0002] Such a printing press is described in DE10040519A1. In such printing presses of the prior art there is an adjustably mounted sheet guide which, when the second cylinder is adjusted to the second cylinder position, is adjusted by means of an adjusting drive to the first cylinder and Between the second cylinder, such that the sheet guide covers the first cylinder in the region of the printing nip, the first cylinder and the second cylinder jointly form the printing nip dur...
