Title (EN) METHOD AND DEVICE FOR FABRICATING MOULDS FROM GRANULAR MATERIAL
(FR) PROCEDE ET DISPOSITIF DE FABRICATION DE MOULES A PARTIR DE MATERIAU GRANULAIRE
Abstract:
(EN) The present method provides for the making of blocks shaped on two faces by means of model plates (10, 11). After depression of the plates, the envelope (17) sealed at (40) containing the granular material (30) is, in its turn, subjected to depression through the tubes (23) and (24) of the armature. The plates are then removed, as shown on the drawing, while the internal depression is mantained. The blocks are juxtaposed, and two adjacents blocks will form a print and their free faces will enable the making of two more with two additional blocks. Thus, (n-1) prints will be obtained for n blocks.
(FR) Le présent procédé consiste à réaliser des mottes mises en forme sur deux faces à l'aide de plaques-modèles (10, 11). Après mise en dépression des plaques, l'enveloppe (17) scellée en (40) contenant le matériau granulaire (30) est, à son tour, mise en dépression par les tubes (23) et (24) de l'armature. Les plaques sont alors retirées ainsi que représentées sur la figure tandis que la dépression interne est maintenue. Les mottes sont juxtaposées et deux mottes adjacentes formeront une empreinte et leurs faces libres permettront d'en créer deux autres avec deux mottes supplémentaires. Ainsi, on obtient (n-1) empreintes pour n mottes.
