ABSTRACT:
A novel printing press for printing a large number of different messages on sequentially fed stock, without requiring the use of a large printing drum, which also eliminates the requirement for collating. A multiplicity of drum segments are provided each having similar radii of curvature, for carrying printing type on their convex surfaces. A pressure wheel is located adjacent a pressure plate, the pressure wheel having a similar radius of curvature as each of the drum segments. The drum segments are carried each in turn around at least part of the pressure wheel between the pressure wheel and pressure plate, whereupon stock fed therebetween can be imprinted.
