<p>The invention is a method for the cold agglomeration of mixtures of metallic and non-metallic powders (P) on to the outer perimetral edge (B) of a core (A), comprising the following operations: positioning the core (A) inside a mould (1) between a pair of core-pressing means (7, 7') opposite each other; distributing the powder mixture (P) on to the outer perimetral edge (B) of the core (A); agglomerating the powders (P) together and on the edge (B) of the core through powder-pressing means (21, 22, 23, 24); shifting the core-pressing means, the powder-pressing means and the core with respect to the plane on which the core is arranged; moving the powder-pressing means away from the powders (P) agglomerated on the edge (B) of the core (A); moving at least one of the core-pressing means (7, 7') away from the core; extracting the core (A) from the mould. <IMAGE></p> |
