Abstract

La présente invention se rapporte à la fabrication de plaques, par coulée, d'un produit évolutif fluide, tel qu'un mélange de plâtre et d'eau. L'invention propose un procédé de fabrication de plaques par coulée, sur une sole mobile, d'un produit évolutif fluide, tel qu'un mélange de plâtre et d'eau, contenu dans une réserve en charge par rapport à la sole de coulée, au travers d'une fente transversale, parallèle et adjacente à la sole de coulée, dans lequel on introduit en continu du produit de renouvellement dans la réserve par une pluralité de jets immergés dans la masse du produit de la réserve. L'invention propose également un dispositif pour mettre en oeuvre ce procédé, et des produits fabriqués par ce procédé. L'invention est applicable à la fabrication de plaques de plâtre.The present invention relates to the manufacture of plates, by casting, of a fluid evolving product, such as a mixture of plaster and water. The invention proposes a method of manufacturing plates by casting, on a bogie, of a fluid evolving product, such as a mixture of plaster and water, contained in a reserve loaded with respect to the casting hearth. , through a transverse slot, parallel and adjacent to the casting hearth, in which renewing product is continuously introduced into the reserve by a plurality of jets immersed in the mass of the product of the reserve. The invention also proposes a device for carrying out this method, and products manufactured by this method. The invention is applicable to the manufacture of plasterboard.
