Abstract:
1. A method for producing a plurality of curved extruded profiles from one of a light metal and a light metal alloy, the method comprising the steps of: simultaneously extruding at least two extruded profiles to have mirror-symmetrically cross-sectional shapes by using an extrusion device, the extrusion device comprising an extrusion tool with an extrusion die shaping the at least two extruded profiles, while simultaneously curving the at least two extruded profiles to have, in the direction of extrusion and in a horizontal viewing plane of the direction of extrusion, a curvature with an algebraic sign opposite to that of the curvature with which at least one of one other extruded profile and a projection of the one other extruded profile into the viewing plane is curved.
