Abstract

A variable data imprinting machine having an elongated flat printing bed section providing a document supporting surface and having a print wheel pack formed of closely adjacent peripherally notched print wheels, an imprinting carriage movable through advance and return strokes longitudinally along the document support surface and an elongated rack case section perpendicular to the printing bed section subjacent the wheel pack having a number-bearing rack control panel projecting therefrom and including a plurality of flexible band-like toothed racks coarse manually adjusted longitudinally in the rack case to rotatably index the print wheels to number-printing positions. The rack case includes serpentine elongated guide slot trackways sized to receive and guide the toothed racks for their longitudinal wheel-indexing movement. A pivoted centering blade is activated by carriage movement to fine adjust the racks as the carriage leaves parked position and interlock means are provided to latch the carriage at parked position following an imprinting cycle until one of the racks is readjusted.
