Abstract
PURPOSE:To improve a magnetization effect for a roll magnet by mixing ferrite particles, binder rubber, etc., rolling the mixture to form a sheet, and laminating the sheets with upper and lower dies having wedge concavities and projections respectively for changing the magnetic orientation in the laminate. CONSTITUTION:The mixture of ferrite flake particles 5 treated magnetoanisotropically and the rubber or synthetic resin medium 6 is rolled with rolling mill to form a magnet sheet 8 having the particles oriented in the rolling direction. Sheets 8 thus formed is superposed upon each other by the desired number of sheets, the super-posed sheets are put between the lower die 11 having several wedge projections different from one another in height and the upper die 13 having wedge concavities 12 corresponding to the projections 10, and pressed thereby to obtain a laminate 9. The laminate 9 thus provided with the wedge cuts 14 is wound around a shaft to form a roll. In this manner the magnetic orientation varies up to about 90 deg. successively, the magnetic flux is liable to pass through the magnetized medium resulting in strong magnetic force.
