Abstract

DANS CE PROCEDE, ON CALE L'EMPREINTE 21 AU SEIN D'UNE MASSE DE PARTICULES MAGNETISABLES 22 QUE L'ON TASSE ET QUE L'ON RIGIDIFIE AVANT LA COULEE AU MOYEN D'UN CHAMP MAGNETIQUE. LE TASSEMENT S'EFFECTUE PAR VIBRATION DU MOULE.IN THIS PROCESS, THE FOOTPRINT 21 IS WEDDED WITHIN A MASS OF MAGNETISABLE PARTICLES 22 WHICH IS PUMPED AND WHICH IS RIGIDIFIED BEFORE FLOWING BY MEANS OF A MAGNETIC FIELD. SETTLEMENT IS DONE BY VIBRATION OF THE MOLD.
