ABSTRACT:
Disclosed is an improved folding and loading mechanism for small, limp, sheet-like articles. A pair of pivotal support trays are biased to form a horizontal platform, upon which each sheet-like article is placed and then folded by pivoting flippers. After folding, a propulsion mechanism moves from a rest position and pushes the support trays out of the way and further pushes the folded article into a carton residing below the platform. Upon return of the propulsion mechanism to a rest position, the biasing on the support trays returns them to again form the horizontal platform. The propulsion mechanism can be a separate stomper member positioned above the platform.
