Patent

CA 2439040

A method is provided for continuous production of gypsum boards which comprises forming a laminate of gypsum slurry between a facing paper (111) and a backing paper (125) and continuously forming a longitudinal recess (203) along the side edges of the laminate surface, and a lateral recess (205) at spaced intervals on the laminate surface thereby producing a four-tapered edge gypsum board (200) which is uniquely suitable as a material of construction in the building industry.

L'invention concerne la production en continu de panneaux en gypse qui consiste à former un laminé de pâte de plâtre entre un papier avant (111) et un papier arrière (125) et à former en continu un évidement longitudinal (203) le long des bords latéraux de la surface du laminé, et un évidement latéral (205) à intervalles réguliers sur ladite surface, ce qui permet de produire un panneau en gypse (200) à quatre bords biseautés convenant particulièrement comme matériau de construction dans l'industrie du bâtiment.
