Title (EN) ELECTROSTATIC ABRASIVE PARTICLE COATING APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE REVÊTEMENT DE PARTICULES ABRASIVES ÉLECTROSTATIQUES
Abstract:
(EN) A method of applying particles to a backing having a make layer on one of the backing's opposed major surfaces. The method including the steps of: supporting the particles on a feeding member having a feeding surface such that the particles settle into one or more layers on the feeding surface; the feeding surface and the backing being arranged in a non-parallel manner; and translating the particles from the feeding surface to the backing and attaching the particles to the make layer by an electrostatic force.
(FR) L'invention concerne un procédé d'application de particules sur un support ayant une couche de fabrication sur l'une des surfaces principales opposées du support. Le procédé comprend les étapes consistant à : supporter les particules sur un élément d'alimentation ayant une surface d'alimentation de sorte que les particules se stabilisent en une ou plusieurs couches sur la surface d'alimentation ; la surface d'alimentation et le support étant agencés de manière non parallèle ; et translater les particules de la surface d'alimentation au support et fixer les particules sur la couche de fabrication par force électrostatique.
