  • Publication number: 20200147954
    Abstract: An apparatus and methods of decorating exterior surfaces of metallic containers are provided. More specifically, the present disclosure provides a novel metering roller for an inking assembly of a decorator. An adjustment mechanism is operable to move the metering roller to a first ink transfer position during a decoration run. In the first ink transfer position, the metering roller receives ink from an ink roller without contacting the ink roller. In one embodiment, during the production run, the metering roller is in contact with and transfers ink to a transfer roller. When the decoration run stops, the adjustment mechanism can move the metering roller to a second dwell position such that the metering roller does not receive ink from the ink roller.
