Abstract

L'invention concerne une plaque d'adhérence à magnétisme permanent La plaque d'adhérence de l'invention est constituée d'aimants permanents 2 disposés dans un logement ferromagnétique, ainsi que d'une plaque de recouvrement 3 servant de surface d'adhérence, recouvrant les aimants permanents 2 et le logement, appliquée directement sur les faces polaires des aimants permanents 2 et ayant une épaisseur dépendant du flux magnétique de ces aimants 2. Des trous 8 sont pratiqués dans cette plaque 3. L'invention est utilisée pour améliorer les propriétés d'adhérence magnétique des plaques de recouvrement
