Abstract

PROCEDE POUR LA FABRICATION D'UN PLATEAU D'ASSUJETTISSEMENT ELECTROMAGNETIQUE QUI EST DIVISE EN AU MOINS DEUX PARTIES POLAIRES A POLARITE VARIABLE EN UNE MATIERE DOUEE D'UNE BONNE PERMEABILITE MAGNETIQUE QUI S'ENGAGENT L'UNE DANS L'AUTRE TOUT EN ETANT SEPAREES PAR UNE MATIERE NON MAGNETISABLE. DES SEGMENTS EN FORME DE PLAQUES, REALISES AU PREALABLE PAR COMPRESSION D'UNE MATIERE EN POUDRE DOUEE D'UNE BONNE PERMEABILITE MAGNETIQUE ET D'UNE MATIERE NON MAGNETISABLE DANS UN MOULE ET PAR FRITTAGE SUBSEQUENT, SONT REUNIS PAR PRESSAGE EN ETANT PLACES LES UNS CONTRE LES AUTRES AVEC LEURS COTES PLATS. L'INVENTION EST APPLICABLE NOTAMMENT A DES PLATEAUX PORTE-PIECE POUR MACHINES-OUTILS.
