ABSTRACT:
An improved extrusion process and apparatus for extruding feedstock is disclosed in which the gripping force for the extrusion is derived by forcing the feedstock into a passageway to develop in the feedstock on two opposing surfaces a pressure of at least the yield strength of the feedstock and moving the feedstock toward a stop and die means located at the end of a passageway and particularly that improvement consisting of providing a fork-shaped element that forms the passageway with a distance between the constraining walls sufficiently greater than the height of the wall surfaces so that no lubrication of the ungripped surfaces of the feedstock is required.
