ABSTRACT:
An applicator in which a coating can be applied to a base material at high speed, a coating film can be thinned and a desired coating film can be obtained when the coating films of two or more layers are simultaneously formed. A die 2 is provided with a slit 5 for a lower layer and a slit 15 for an upper layer which respectively serve to extrude a coating 6 for the lower layer and a coating 16 for the upper layer to the base material. The coatings 6 and 16 are respectively extruded from these slits 5 and 15 to the continuously running base material 1 so that the coating films of two layers are formed. Lower layer lips 4 forming the lower layer slit 5 are provided so as to be not in contact with the base material 1. Upper lips 14 forming the upper layer slit 15 are provided so as to abut on the base material 1. When a magnetic coating is used as the coating 6 for the lower layer, a magnet part may be opposed to the lips 4 for the lower layer by sandwiching the base material 1 therebetween.
