ABSTRACT:
Apparatus and process for gauging and controlling extruded profiled elements, particularly extruded profiled elements made of synthetic material. The apparatus includes at least one control and correction gauge arrangeable downstream of an extrusion die along the extrusion direction and in which there is a passage shaped so as to match the profile of the extruded profiled element. The passage can be crossed by the extruded profiled element, and there are holes and/or channels for heating and cooling preset regions of the profiled element to correct the profile and/or the internal tensions of the profiled element.
