ABSTRACT:
A signature ejecting assembly for use in a folding apparatus in a printing press. A first rotatably mounted surface is provided, and a second rotatably mounted surface is movingly mounted on a bracket. The first and second rotatably mounted surfaces located within the product transfer area or nip of the folding apparatus. The second rotatably mounted surface exerts a positive drive force upon loosely held or bunched signatures during start-up, thereby ejecting the signatures and preventing jams in the folding apparatus.
