BREITSCHLITZDUESE FUER EINE STRANGPRESSE

摘要

An extrusion die has an extrusion orifice defined on at least one side by a resilient steel strip that extends transverse to the direction of extrusion. The strip is secured to the die at its upstream edge and is free along its downstream edge. A plurality of elements are adjustable in a direction perpendicular to the direction of said extrusion and perpendicular to the length of the strip and bear against the downstream edge of the strip on the side opposite the side along which the material is extruded, so as variably to shape the resilient strip thereby to determine the contour of the extrusion orifice. The means for adjusting the elements can be screw means or hydraulic means.
