Abstract:
1. A molding system for an extrusion plant, comprising a calibration die which has inlet and outlet faces spaced at a distance apart from each other and side faces extending therebetween, a calibration orifice extending between the inlet and outlet faces of the calibration die and bounded by interconnected shaping surfaces including at least one displaceable and one stationary shaping surface, the displaceable shaping surface having three interconnected parts extending at an angle to each other, the shaping surfaces enclosing an external profiled section of an object fed through the calibration orifice from the inlet face to the outlet face, and at least one gap within the calibration die and extending over the distance between the inlet and outlet faces, the gap having three interconnected parts extending in a plane parallel to the inlet and outlet faces and forming a substantially U-shaped gap, the gap being disposed adjacent interconnected parts of a respective one of the displaceable shaping surfaces for enabling said interconnected displaceable shaping surface parts to be repositioned together relative to a respective one of the stationary shaping surfaces.
