Abstract
A molding device for molding articles of plastic material such as ground raw meat to make hamburger patties and the like while at the same time limiting the maximum total pressure applied to the material. The device comprises a hopper for the material, a mold with a mold opening adapted to communicate with a pressure chamber for receiving pressurized material from this chamber and transfer means in the hopper for moving the material toward an exit portion of the hopper leading to this pressure chamber. In order to direct the material from the transfer means into the pressure chamber there is provided a pressure confining baffle in the hopper with sufficient clearance between the baffle and the transfer means to permit escape of material around the baffle back into the hopper.
