发明名称 METHOD OF PRODUCING ROLL-TYPE MAGNET
摘要 A process for producing roll-shaped magnets which may be used in electrophotographic copying machines or the like. At least two types of composite magnet sheets of different magnetic characteristics, each having a magnetic orientation in the thickness direction, are superposed to form a laminated body. A plurality of wedge-shaped indentations are formed in one side of the laminated body. The laminated body is then wound around a shaft so that its surface having the indentations constitutes the inner peripheral surface. A magnetization is then effected. This process conveniently permits the full magnetization of the laminated body to ensure a high quality and superior characteristic of the products, as well as a high productivity. during the mass production of such magnets.
