Abstract

a. Procédé pour la transformation de masses plastiques, en particulier de masses céramiques, par extrusion suivant le brevet principal. b. Procédé caractérisé en ce que les différences des flexions élastiques en retour sont exclues ou réduites en imprimant à la masse céramique une dilatation dans les quadrants à compression d'un outil à former et une compression dans les quadrants à dilatation, dont les valeurs absolues ne doivent pas être inférieures à la dilatation prédéterminées sur le pourtour. c. Procédé applicable à la fabrication de briques creuses.
