Abstract
PURPOSE:To improve the uniformity of coating of a coating liquid by providing two pieces of revolving rolls to the rear face of a plastic film on the front face of which a thin ferromagnetic film near the coater head. CONSTITUTION:The plastic film 1 on the front face of which the thin ferromagnetic film is formed is guided and fed by guide rolls 3a, 3b from an original roll 2. The two revolving rolls 5a, 5b are provided near the coater head 4 between the guide rolls 3a and 3b in a manner as to extend the plastic film 1 under conveyance so that the coating liquid is coated on the surface of the plastic film 1 by the coater head 4 in the position between the rolls 5a and 5b. The distance between the two revolving rolls 5a and 5b is set at <=1/5 the width of the plastic film to be subjected to coating in this case. The unequal coating when the low-viscosity coating liquid is coated is thereby improved.
