Title:
METHOD OF PRODUCING ROLL-TYPE MAGNET
Document Type and Number:
WIPO Patent Application WO/1980/000196
Kind Code:
A1
Abstract:
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.
