ABSTRACT:
The apparatus is positioned at the exit end of a high speed printing machine having a cylindrical printing plate on a driven shaft. A framework of the apparatus is mounted to the exit end. A first shaft is journalled to the framework and indicia marking means are provided axially adjustable on and rotatable with the first shaft for marking selected indicia on material. Indicia changing means are provided for changing the indicia and actuating means selectively actuate the indicia changing means to change indicia after a number of revolutions of the first shaft. A second shaft is rotatably journalled to the framework parallel to the first shaft. A third shaft is pivotally mounted to the second shaft. A drive drivingly couples the second shaft to the third shaft. Pneumatic means are provided for moving an impression roller on the third shaft between a lower position and a raised position where the periphery of the impression roller has a tangent with the circular path of the indicia marking means. Drive means couple the driven shaft for the printing plate to the first and second shafts. The drive means include timing means for adjusting the time and position of the marking of indicia on the material relative to the time of printing on the material by the printing plate. Control means are provided for controlling the operation of the actuating means and the roller moving means and positioning means are provided for adjusting the axial position of the indicia marking means on the first shaft.
