ABSTRACT:
A conveyor belt of medium-soft thick material is advanced, and a film of polymer material is laid thereon to advance therewith. A moldable material, usually a food material, is extruded onto the advancing base film. A portion-forming wheel having portion cavities around the periphery thereof is positioned with its portion cavities facing the conveyor belt. A cover film is fed onto the portion-forming wheel and is preferably drawn into the portion cavities. As the conveyor belt advances, the portion cavities cut the extrusion of moldable material into individual portions which are enclosed by the two films as the conveyor belt advances. The portion cavities have portion-cutting walls therebetween, and a ramped area around the cavity squeezes all of the moldable material into the portion cavities.
