Title (EN) METHOD OF PRODUCING ROLL-TYPE MAGNET
(FR) METHODE DE PRODUCTION D"UN AIMANT EN FORME DE CYLINDRE
Abstract: front page image
(EN)A method of producing a roll-type magnet adapted to be used in electrophotographic reproducing machines etc., in which several notches (13) are formed on one side of a laminate (9) composed of two or more kinds of composite magnet sheets which are oriented magnetically in the direction of rolling and have different magnetic properties from each other, and said laminate is magnetized after it is wound around a shaft (14) with its notched side inside. According to this method, the product is superior in quality and properties, full magnetization is possible and high productivity is obtained.
(FR)Une methode de production d"un aimant en forme de cylindre destine a etre utilise dans des machines de reproduction electro-photographique, etc., dans laquelle plusieurs entailles (13) sont formees sur un cote d"un lamine (9) compose de deux ou plusieurs types de feuilles d"aimant composite qui sont orientees magnetiquement dans le sens de rotation et possedent des proprietes magnetiques differentes les unes des autres, ledit lamine etant magnetise apres avoir ete enroule autour d"un arbre (14), son cote a entailles etant a l"interieur. Selon cette methode, la qualite et les proprietes du produit sont superieures, la magnetisation totale est possible et on obtient un rendement eleve.
