To certainly prevent the leak of a cement slurry from the upstream side in the transfer direction of a base surface when the cement slurry is formed into a layer on the base surface in a flowon molding method.
In a cement slurry supply apparatus in a flow-on molding method wherein the upper surface of a felt belt 1 or on the upper surface of the cement layer 2 transferred while formed into a strip-like layer on the felt belt 1 is set to a base surface 10 and a bottomless frame member 3 is arranged on the base surface 10 and a cement slurry outflow gap 4 is provided on the transfer downstream side of the felt belt 1, the side lower edge 3A on the transfer upstream side of the felt belt 1 of the frame member 3 is made higher than the base surface 10 and a flexible waterproof sheet 5 is suspended in a loosened state from the lower edge 3A to the upper surface of the base surface 10.
