ABSTRACT:
An apparatus and method for shaping an article from moldable material and particularly a food article as from ground raw meat, fish and the like to produce firmly packed articles with relatively low power requirements while avoiding the entrapment of extraneous air in the article. The apparatus and method also include seals for sealing the mold and mold opening against substantial loss of liquid components during the molding. The material is pressure fed into a mold opening provided with an air vent means and the entering charge of material vents the air from the mold opening and then the material itself operates a valve to close the air vent against substantial losses of even liquid components of the moldable material.
