Printing coder

摘要

A coder for imprinting the tops of crowns, closures or the like which includes a floating print roll which is independently fine turnable to accomodate height variations in the items being encoded, said print roll being lever supported for quick release from an ink metering roll upon being raised by the item to be imprinted. The print roll is rotatably driven by the items to be imprinted and the metering roll and inking roll of the coder are both preferably driven to relieve wear between the inking and metering rolls.
