Abstract:
A production process is provided for a board of hydraulic binder with a facing on each of its sides. The process includes on one side first tapered parallel edges and on the same side or the other side, two second tapered parallel edges perpendicular to the first. The process also includes the use of a forming lath having at least two distal parts. The process can be used in a production line that includes a specific lath.
