AN INSTALLATION FOR THE CONSTRUCTION OF A CORE FOR THE MANUFACTURE OF AN OBJECT BY DEPOSITING ON THE CORE

摘要

a reservoir (60) capable of containing a pulverulent fluidizable solid material (6); means for handling a first mold (5) the molding surface of which at least partially defines the outer surface of said core, said molding surface being open, said core being a torodial core used for the manufacture of a tire; means for holding a rim (1) comprising a middle portion connecting two annular lateral anchoring zones; means for manufacturing an air-tight membrane (2) which is deposited on said molding surface of the first mold (5), and for creating a cavity of predetermined volume and shape by closing said opening by means of said support (1) in order to define a closed space between the support and the membrane; means for transferring sad material from the reservoir towards said closed space and, vice versa, in such a manner that said material can occupy the entire volume of said cavity
