Abstract: A paper feed system suitable for use with a portion control machine to provide paper sheets for separating portions, including a paper hopper mountable to a portion control machine and adapted to receive and temporarily retain a stack of paper sheets. The paper hopper has an open end having a front edge spaced opposite from a back edge and defining a ready position where a paper sheet lies in a first plane to be dispensed. The paper feed system further includes a paper support having a length to width ratio of 10 to 1 or greater. The paper support is mounted adjacent the open end of the paper hopper blocking the free exit of paper sheets therefrom, with the support extending from a central location on the back edge partially to a central location on the front edge. An upper surface of the support is substantially parallel with the first plane and is adjacent the first plane for retention of a paper sheet in the ready position.

Abstract: A method and apparatus for molding food patties, utilizing a pump with a tall, narrow, elongated pump chamber, an outlet port extending along one edge of the chamber, and a wide access port at one side of the chamber. A supply of hamburger or other poor-flowing food product is maintained in a position completely blocking the pump access chamber and can be drawn into the chamber by rapidly withdrawing a plunger from the chamber past the access port. A hydraulic drive powers the plunger, in synchronism with a mold plate cyclically moving into and out of a fill position beneath the outlet port; the hydraulic drive causes the plunger to pump food out of the pump chamber and into mold cavities in the mold plate under a constant pressure, with the hydraulic pumps of the drive cut off immediately following filling of the molds.
