摘要:
A metal extrusion process and apparatus therefor in which a strip material of a rectangular shape may be produced by maintaining frictional engagement of the metal by passageway-defining surfaces of a member which is moved toward a die such that the frictional drag of the passageway-defining surfaces urges the metal through the die. The process utilizes strip material as the starting material which enables the extrusion of metal strip by the frictional drag process to be accomplished.
