Abstract
A method for producing building boards includes unwinding a facing sheet from a supply roll of facing sheet over top of a forming table that includes a series of nozzles. A volume of cementitious material is deposited from a slurry mixing device to the unwound facing sheet. Pressurized air is supplied from an air source to the series of nozzles, whereby a cushion of air is created between the unwound facing sheet and the forming table.
