Title Method for Making Cement Board Abstract of the Disclosure Mortar is deflected continuously onto a moving carrier sheet from a distributor belt which is moving transversely to the carrier sheet by a plow which shuttles across the length of the distributor belt. An uninterrupted flow of mortar is spread across the sheet. The layer of mortar on the carrier sheet is slightly undulatory in the machine direction but a lateral cross section has a substantially uniform thickness so that a flat broad ribbon of mortar emerges from under a screed downstream from the shuttle plow.
