Abstract
The invention relates to methods for manufacturing lightweight building boards () starting from a workpiece () which comprises two thin-walled cover layers () and at least one core layer () which is disposed between the cover layers () and is made of a light filling material, the at least one core layer () possessing cavities and having a lower average density than the cover layers. The method comprises the following steps: forming in the workpiece () at least one groove () which extends through at least one first cover layer () and at least partly through the at least one core layer () and circumscribes at least a portion of a contour of the lightweight building board () to be manufactured; introducing a hardenable mass () into the at least one groove (); at least partly hardening the hardenable mass (); and making a separating cut along the at least one groove (), so the at least partly hardened mass () is separated in the longitudinal direction of the groove.
