Three or more extruders (1,2,3) supply separate extrudates (5a,5b,5c) of the same material along flow lines to an extrusion die. The die is divided into three or more areas (4a,4b,4c) each fed by one of the extrudates. An Independent claim is also included for a process for extruding profiles, in particular window profiles, in which three extrudates controlled independently from each other are fed separately to each area of the die where they are combined as a single extrudate and calibrated (6). |
