ABSTRACT:
A removable numbering and imprinting device cooperable with a printing cylinder of a sheet-fed offset machine and located between the rubber cylinder and the sheet delivery includes a numbering shaft mounted on the machine frame and detachably carrying a plurality of numeral units. A self-contained structure defining an inking mechanism is mounted on the machine frame and operable to ink the numeral units. The inking mechanism is readily removable from the machine frame separately from the numbering shaft and the numeral units, whereby removal of the inking mechanism from the machine frame provides ready access to the numbering shaft and the numeral means.
