Abstract

PURPOSE: To let magnetization easy axes of magnetic anisotropy be evenly oriented on film surface by providing magnetic potential differences between a doctor blade and a roller for coating magnetic powder-contained coating.
CONSTITUTION: A doctor blade 2 integrated with an accommodating part 6 which accommodates magnetic powder coating and a roller 3 are composed of a magnetic material. The roller 3 is supported by a bearing 10 composed of the magnetic material fixed to a base 11 in bearing part 8 by way of a sleeve 9. The blade 2 is fixed by bonding or other techniques to the upper end of the earing 10 via the two permanetnt magnets 7 of a precisely set length. Here, the two magnets 7 are both held magnetized in the same direction in the vertical direction. In this way, magnetic potential defferences occur between the blade 2 and the roller 3
