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