VERFAHREN ZUR KÜRZUNG DER BREITE UND/ODER DER LÄNGE EINER SANDWICHPLATTE

The invention relates to a method for changing the width and/or length of a sandwich construction unit, said construction unit (1) comprising a core element (2) of some thermally insulating material, having edge-profiled surface sheets (3, 4) attached to its two opposite major surfaces. The method comprises splitting and/or breaking the unit (1) by cutting it longitudinally and/or laterally along a desired line, followed by removing a piece of core element material (2a) from alongside the cut edge to enable edge-profiling devices (8) to fit in a space between the surface sheets (3, 4), followed by profiling a cut edge (5a) of the surface sheets and by replacing the removed piece of core element material (2a) with a fresh piece of core element material (2b).
