Abstract (en)
[origin: EP0244702A2] A varnishing device conceived as a modular unit features dosing roller, applicator roller and pick-up roller for coupled working with a printing machine, which in their relative positions to one another and to the impression cylinder of the printing machine are adjustable such that a precise, pre-determinable quantity of varnish can be applied to the impression cylinder of the printing machine or the printed product situated there. In particular, the applicator roller and the dosing roller are mounted in a common carriage-like roller frame, which can be brought into contact with the printing machine by means of an eccentric drive. In the normal situation, i.e. when the printing machine is running, the drive of the varnishing device comes from the printing machine itself; if the printing machine is at rest, an auxiliary motor switches itself on and turns the rollers in order to prevent partial or complete drying of the varnish. The varnishing device is easy to adjust and control.
