Abstract
An extrusion-type application device with which a liquid can be very rapidly applied to a carrier to form a thin layer thereon without causing streaking in the applied layer. The liquid is continuously expelled from the outside part of a slot to the surface of a flexible carrier continuously moving at a speed of 300 m/min or more along the surface of a back edge portion and the surface of a doctor edge portion so that the liquid is applied to the surface of the carrier. The surface of the doctor edge portion is curved, the inner longitudinal edge B of the surface of the back edge portion is located at the outlet of the slot so that the angle .theta..sub.1 between a tangent to the surface of the back edge portion at the inner longitudinal edge B and a tangent to the surface of the doctor edge portion at the outer longitudinal edge A of the surface of the doctor edge portion and the angle .theta..sub.2 between the former tangent and a tangent to the surface of the doctor edge portion and to the inner longitudinal edge B are as follows:
