ABSTRACT:
A method of and apparatus for the manufacture of metal extrusions is disclosed in which the metal is extruded through a die having, preferably, a single extrusion aperture. The leading end of the extruded section is gripped and pulled away from the die by a puller 11, and the section is at the same time rapidly and uniformly cooled in a tunnel 8 as extrusion proceeds. When the puller reaches a predetermined distance from the die, the puller and extrusion are stopped simultaneously. The extruded section is then gripped in a device 12 including a pair of gripping jaws adjacent the die and shearing means by which the section is cut through at a location between this pair of jaws and the die. The puller is then operated to move it to stretch the extruded section while the section remains gripped by the gripping jaws of device 12 and in alignment with the die.
