摘要： A method of applying at least one liquid to a surface of a carrier includes providing an extrusion-type application head having a slot with an outlet portion and a back edge portion, pushing the outlet portion of the slot toward the surface of the carrier, continuously conveying the carrier along a surface of the back edge portion of the head, and thereafter applying a liquid undercoating in excess to the carrier surface in advance upstream of the head relative to a conveyance direction of the carrier so as to form a liquid undercoating layer on the carrier surface. The liquid is continuously jetted from the slot so that the liquid is applied to the liquid undercoating. As a result, air does not form between the liquid undercoating and the subsequent liquid applied, and the applied liquid has a uniform thickness despite the application speed of the liquid (e.g., conveyance speed of the carrier) being great.
