ABSTRACT:
A mold station of a food patty molding machine in which a food pump pumps a moldable food product through a fill passage into mold cavities in a cyclically reciprocating mold plate, with a multi-orifice plate interposed in the fill passage and a stripper plate, slidably mounted immediately adjacent the orifice plate, having a multiplicity of fill openings aligned one-for-one with the fill orifices; a stripper plate drive, synchronized with the mold plate drive, slides the stripper plate a short distance to a seal-off location once in each mold plate cycle. The spacings between fill openings in the stripper plate are made large enough to close all of the fill orifices when the stripper plate is moved to its seal-off location; the stripper plate drive shifts the stripper plate to its seal-off location before movement of the mold plate toward its discharge position can create an open outlet path from the food pump through the mold cavities to outside of the mold station.
