Abstract: Reinforced cement panels are produced between a fixed lower mould and a movable upper mould each having a moulding surface covered with filter cloth. Suction is applied through ports in the lower mould to extract air and residual water, reinforcement is placed on the lower mould, a layer of slurry of uniform thickness is applied by traversing a depositor over the lower mould, and the upper mould is rested on the surface of the slurry. Vacuum is applied through arched connections from upper parts of manifolds on the upper mould and through passages in the upper mould to the filter cloth thereof to withdraw moisture from the slurry to create an uncured panel. Water-containing foam is admitted through the ports in the lower mould to release the uncured panel, whereupon the upper mould is raised with the uncured panel held thereto, traversed to a different position to rest the uncured panel on a support.
