A system for continuous manufacture of building elements consisting of a self-supporting framework of tightly compressed solid particles and a foaming material in the shape of a foamed plastic material, comprises a filling station where mould bottoms are placed in continuation of each other on a roller conveyor, assembled with sidewalls and passed along a guide section (8), wherein particle-shaped filler is supplied from a silo (9) while a premixed foam material is injected into the material through nozzle tubes (12), and the components are mixed before being injected into the mould and compressed. After placing of a top wall on each of the moulds, these are passed under a roller conveyor (3), and while the moulds are moved ahead between the roller conveyors (1) and (3) and possibly between roller conveyors outside the side, the foam material cements the particles together to a monolithic unit which will set before the moulds leave the roller conveyors (1, 3). After demoulding of the formed flow of material, this is cut by a cutting mechanism G into required lengths, and the moulds are carried back to the filling station. |
