Abstract (en)

[origin: WO03040509A1] The invention relates to a door leaf, preferably for an interior door, and to a method for producing the same. The aim of the invention is to provide a door leaf for a double-wing door or revolving door, which is relatively light-weight and stable and which can be opened using normal force. The outer layer should consist of a layer that is break-proof, scratch-resistant and not susceptible to shocks and should be securely linked with the subject layer without complications. The use of water should be possible during the production of the door without damaging the door leaf. According to the invention, cover plates are glued onto the entire surface of both sides of an inner layer that has a suitable size for a double-wing door or revolving door. At least one of the one-piece cover plates consists of natural stone or artificial stone. During production of the door leaf the inner layer is foamed from high-resistance plastic foam in a mold and is removed from the mold after setting and then glued together with the cover plates. The cover plates are cut down to minimum thicknesses and/or ground down (calibrated). Alternatively, the inner layer is foamed from high-resistance plastic foam in a mold. The cover plates are first inserted in the mold at a distance to each other and then foamed to the inner layer. After setting, the door leaf is removed from the mold and the cover plates are cut down to minimum thicknesses and/or ground down (calibrated).
