Abstract

a. Procédé de traitement d'un produit composite consistant en un composé de moulage à l'état de moulage préalable renfermant des fibres de renforcement, ce produit composite étant maintenu en couche entre les faces de deux feuilles minces continues de maintien. b. Ce procédé consiste à utiliser une première courroie mobile sans fin présentant une face tournée vers le haut; utiliser une seconde courroie mobile présentant une face tournée vers le bas, très voisine de ladite face tournée vers le haut de la première courroie, et à faire défiler lesdites feuilles de maintien et le produit composite qu'elles enferment, entre cette surface tournée vers le bas de la courroie sans fin et cette surface tournée vers le haut. c. Fabrication de composés de moulage renforcés en feuille.at. Process for treating a composite product consisting of a molding compound in the pre-molding state comprising reinforcing fibers, this composite product being held in a layer between the faces of two continuous thin retaining sheets. b. This method consists of using a first endless moving belt having one face facing upwards; use a second moving belt having a face turned downwards, very close to said face turned upwards of the first belt, and to make said retaining sheets and the composite product which they enclose, pass between this surface facing towards the top bottom of the endless belt and this surface facing up. vs. Manufacture of sheet reinforced molding compounds.
