Abstract (en)
[origin: US7001645B1] The invention seeks to provide a magnetized coating suitable for exerting durable magnetic forces. To do this, the method of the invention consists in spreading conductive particles ( 13 ) on a medium ( 11 ), the particles being directed by prior magnetization along an inducing magnetic field and being embedded in a binder ( 12 ). The coating apparatus for implementing the method of the invention comprises means ( 10, 15 ) for feeding the medium ( 11 ) onto a conveyor ( 20 ), means for applying a main binder ( 12 ) via presser rollers ( 40 ) and via at least one nozzle ( 30 ), said means being coupled to heater means, a tank ( 50 ) of particles ( 13 ) coupled to a duster ( 51 ) for dispensing the fill of particles, means for spreading the fill of particles within the main binder, electromagnetic means ( 60 ) for producing an anisotropic magnetic field for magnetizing the particles, a sprayer ( 80 ) for depositing an additional binder, dryer means ( 100 ), demagnetizer means ( 110 ), and winder means ( 120 ). The invention is applicable to media particularly in paper-making, games, decoration, or building.
