A mailroom conveyor system for transporting and handling a stream of printed and folded signatures supplied by high speed tapes of a folding apparatus of a printing press. The system includes a plurality of grippers, a rail system for guiding the grippers, an electric linear drive system for individually driving the grippers in the rail system, and a control system coupled to the electric linear drive system for individually controlling the movement of the grippers in the rail system.

An inker and form roller unit for a printing press includes a continuously rotating fountain roller for carrying ink from a reservoir. A combi-roller is in constant contact with a distribution roller to deliver ink to rollers of the printing press. The combi-roller and distribution roller are supported by a swivel lever that can pivot about the rotational axis of the distribution roller. The swivel lever carries a cam roller for contact with a control body having two or more sections, one of which is for continuous film inking and the other section for intermittent inking. The combi-roller is positioned relative to the fountain roller by the control body so as to form either a continuous fluid transfer gap or an intermittent fluid transfer gap.
