Abstract

298,824. Welter, A. Jan. 11, 1928. Extrusion machines.-The mouthpiece of an extrusion press for producing finely-divided material is formed by a thin plate stiffened against bending, and furnished with perforations between the limits of 0.4 and 2 millimetres in diameter. Figs. 1 and 2 show a finely-perforated plate 1 of a thickness about one millemetre, which is stiffened by the cellular plate 3. Preferably the plate 3 is the outer one in use and has hexagonal cells, while the small holes are tapered with the larger diameter inwards. In other constructions the thin plate is of cylindrical, conical, or truncated conical form and is stiffened by metal straps 5, Fig. 6.
