Switching device for a combined damping and varnishing unit

摘要

The invention relates to a switching device for a combined damping and varnishing unit in sheet-fed offset printing machines. The object of providing a switching device for a combined damping and varnishing unit, which prevents sticking of the varnish application roller both in damping operation, which maintains pre-damping of the damping roller which has a favourable effect on the printing process, and in varnishing operation, is achieved in that a change-over switch for damping and varnishing operation in the form of an adjustable eccentric is arranged below a double lever of the switching device.
