Abstract
A paper interleaver for a food patty molding machine of the kind using a mold plate cyclically reciprocating along a linear path between a fill position and a knock-out position comprises a shuttle connected to the mold plate for synchronous movement along a linear path between a transfer position and a pickup position. When the mold plate is at its knock-out position and the shuttle at its pickup position, the shuttle pulls a single paper sheet from the bottom of a storage stack by vacuum; when the mold plate and shuttle are at their respective fill and transfer positions, the shuttle 'puffs' the paper sheet up a very short distance to be held by downwardly facing vacuum ports of a fixed paper holder frame, essentially immune to clogging from the food product particles and juices present at the knock-out position. A molded patty subsequently moves down through the frame to pick up the paper sheet when the mold plate returns to the knock-out position. A grooved spindle at the paper storage stack cooperates with a shallow tapered groove in the stack support surface to assure a flat configuration for the paper sheets and elimination of paper particles.
