A method is described for the continuous production of glass fiber mesh reinforced concrete panels consisting of a layer of light weight concrete core mix bonded to a web of glass fiber mesh on each face. An uncured ribbon of reinforced concrete is first formed, suitable for cutting into individual panels. A new method of depositing the cement slurry or core mix on the web of fiber glass has been developed; this is accomplished by conveying the web over a reversely-turning pumping roller which transfers a controlled amount of slurry or core mix to the web.

In the continuous production of fabric reinforced cementitious panel webs suitable for cutting into panel lengths in which a first web of previous reinforcing fabric, a layer of cementitious core composition and second web of pervious reinforcing fabric are deposited on a moving conveyor belt to form an uncured ribbon of fabric reinforced cementitious composition, the improvement which comprises passing at least one of said webs over a reversely turning pumping roller partially immersed in a flowable cementitious composition thereby filling the openings in, and coating the upper and lower faces of, said web with said flowable cementitious composition, and transferring said web in a non-tensioned condition by means of a draping action onto said conveyor belt or a said first web of previous reinforcing fabric.
