ABSTRACT:
A pusher block assembly is provided for use in the aligner section of a printing press. The assembly includes a pusher which automatically tilts rearwardly and translates downwardly at the discharge end of the aligner section, thereby preventing damage to the trailing edges of the articles transferred to the printing section of the press. The pushers are also pivotable between upright and horizontal positions. This feature eliminates the need for removal of the pusher block assembly when relatively long articles are conveyed by the aligner section.
