摘要

Production process for a board of hydraulic binder, production line for boards, based on hydraulic binder, and slat having two distal portions separated by a central portion.The invention provides a production process for a board of hydraulic binder with a coating on each of its sides, comprising on one side, the first two tapered parallel edges (10), and on the same side or on the other side of the second other edges parallel to Filadas (35bis) perpendicular to the first.The said process comprising the use of a slat conformadora (6) having at least two distal parts (61, 62). The invention also provides a production line and a lath structure.
