Abstract
Sealing device for a dampening unit of an offset printing machine having a dampening-medium applicator roller and a metering roller rolling on one another so that a duct for receiving a supply of dampening medium therein is formed by an upper wedge located between the metering roller and the applicator roller, and having a sealing support bracket mountable on a lateral part of the dampening unit pre-stressed in a direction towards an end face of the rollers, and a sealing element held by the sealing support bracket and sealingly supported radially on the metering roller and sealingly engaging the end face of the dampening-medium applicator roller. A path is defined for swivelling the sealing element into a make-ready position wherein the sealing element is removable from the sealing device, the path being left free by the sealing support bracket so that the sealing element may be turned about the metering roller.
