Abstract

761,387. Extruding. SCHLOEMANN AKTGES. Feb. 15, 1954 [April 17, 1953]. No. 4341/54. Class 83 (4). In the extrusion of solid profiles from light metal, particularly aluminium, an extrusion die 1 is used having a fillet-like projection 10 surrounding the die orifice 6 on the end surface 7 facing the oncoming extrusion metal, said projection being adapted to cut into the oncoming metal during extrusion. This projection is preferably acute-angled and facilitates the flow of material through the orifice. The latter may be of square or of L-shaped cross-section, Figs. 1, 3 (not shown). The height of the projection may become progressively less and/or the projection may become blunter from the outside towards the centre 10a so as to obtain uniform flow through the orifice. Specification 722,210 is referred to.
