ABSTRACT:
A rotary printing press assembly having a plurality of serially arranged printing units includes a chain conveyor apparatus for sequentially continuously moving a material web through the successive printing units of the assembly. The forward end of the material web to be passed through the assembly is looped about a lead-in bar which is then engaged by a chain conveyor in order to pass the web through the printing units. A pivoted pawl engaging mechanism fixed to the chain conveyor locks in engagement with a recessed cam surface of the lead-in bars while a locking bolt enters a bore in the lead-in bar to effect driving engagement between the lead-in bar and the conveyor chain. When the lead-in bar has passed through a printing unit the driving pawl is automatically disengaged from the conveyor chain of the printing unit, and for lead-in bar is transferred into engagement with the conveyor chain of a next printing unit. In this manner, the material web attached to the lead-in bar is continuously sequentially passed through the press assembly.
