Abstract

See full text

A method and apparatus for producing light-weight construction panels having a cementitious core layer surfaced with a layer of reinforcing fabric bonded to the two faces of the core includes the use of slurry applicator having a supporting member and a doctor in addition to a moving carrier for the slurry coated fabric. The edges of the panel also are covered with the fabric and may be open mesh edges. Cementitious slurry, for example, portland cement slurry, is applied to the fabric by means of a supporting member over which the fabric is drawn and a doctor means adjustably mounted above the supporting member. The supporting member is of a non-base-reactive material such as polypropylene or stainless steel; the use of such a supporting member permits better application of the slurry to the fabric before placement of the slurry coated fabric on the moving carrier.
