A lacquering mechanism for use with a rotary label printing press comprises a reservoir 10 to accommodate a lacquer to be applied to the printed labels 17, a lacquer metering chamber 13 and a pump 11 for supplying lacquer to the chamber from the reservoir, and an anilox roller 14 onto which lacquer is supplied from an outlet of the metering chamber. A coating roller 15 is located between the roller 14 and a print roller 16 of the press and a blade 18 adjacent to the anilox roller deflects any excess lacquer applied thereto by the metering chamber. The excess lacquer is collected in a tray 19 and returned to the reservoir under gravity. The metering chamber 13 is mounted for reciprocation parallel to the axis of the anilox roller 14. The lacquer is supplied from the metering chamber through spaced-apart orifices of adjustable size. <IMAGE> |
