A method and an apparatus are described for producing lightweight construction panels having a cementitious core surfaced with a layer of reinforcing fabric bonded to the two faces of the core. The edges of the panel also are covered with the fabric. Cementitious slurry, for example, portland cement slurry, is applied to the fabric by means of a supporting plate over which the fabric is drawn and a doctor blade adjustably mounted above the plate. The supporting plate is of a non-base-reactive material such as polypropylene; the use of such a plate permits better application of the slurry to the fabric. |
