ABSTRACT:
A device for varnishing printed sheets in a printing machine. The varnishing device includes a varnish pan, a varnish dipping roller and a metering roller for transferring varnish onto a varnishing cylinder. The dipping roller and the metering roller have a drive that can be connected to the printing machine drive mechanism by an overrunning clutch. The printing machine also includes an auxiliary motor by which the dipping roller and the metering roller can be driven when the printing machine is at a standstill. A torque transmission device, for driving the dipping roller and the metering roller, is also provided. The torque transmission device is connected between the auxiliary motor and the dipping and metering rollers. The torque transmission device does not include a rigid rotary connection apparatus for driving the dipping roller and the metering roller.
