PCT No. PCT/DK83/00126 Sec. 371 Date Aug. 21, 1984 Sec. 102(e) Date Aug. 21, 1984 PCT Filed Dec. 21, 1983 PCT Pub. No. WO84/02489 PCT Pub. Date Jul. 5, 1984.A method and apparatus or system for the continuous manufacture of building element consisting of a self-supporting framework of tightly compressed solid particles and a foaming material in the shape of a foamed plastic material, includes the use of a filling station where mold bottoms are placed in series on a roller conveyor, assembled with sidewalls and passed along a guide section, wherein particle-shaped filler is supplied from a silo while premixed foam material is injected into the material through nozzle tubes and the components are mixed before being injected into the mold and compressed. After placing of a top wall on each of the molds, these are passed under a roller conveyor, and while the molds are moved ahead between the roller conveyors and possibly roller conveyors outside the sidewalls, the foam material binds the particles together to form a monolithic unit which will set before the molds leave the roller conveyors. After demolding of the formed flow of the material, it is cut by a cutting mechanism into the required lengths and the molds are carried back to the filling station. The product is a building element of firmly compressed hard expanded burnt clay particles forming a coherent supporting skeleton of abutting particles bound together by a cured polyurethane foam in only an amount sufficient to fill the cavities between the compressed particles. |
