Abstract
A plate material tensioning and advancement mechanism is disposed in parallel relation to a cylinder, such as a plate cylinder of a printing press, so as to separate the plate material into distinct printable sections. The plate material tensioning and advancement mechanism assists in supplying tension to the plate material via a tensioning roll during printing operation and assists in winding fresh plate material about the cylinder during advancement operation by reducing the tension on the plate material and by optionally applying tangential force to the plate material via a winding roll.
