PURPOSE:To eliminate the need of the stop of running for the gathering of foreign matters and the cleaning of contamination of resin and the like by a method wherein a specified amount of resin flowing down on the surface of base material of the uppermost stage is applied over the whole width of the base material and overflowed resin flows down on the surface of the base material of the next stage and, in the manner same as in the upper stage, flows down on the surface of the base material of the lower stage and finally liquid resin, which processes and flows down over the respective stages, is sent back for circulation to the surface of the base material of the uppermost stage after being replenished with fresh resin. CONSTITUTION:Each hollow pipe 6, which contacts the top surface of base material 1 of each stage horizontally and normal to the running direction of the base material, is provided under the condition that a resin influx port 8 is provided at the upper part of one end of the pipe, a resin discharge port 9 is provided at the lower part of the other end of the pipe and a slit 7, which has the same length as the width of the base material, is provided at the part, which contacts the surface of the base material, of the hollow pipe 6 so as to be controllable a gap between the slit and the surface of the base material. Liquid resin flows in the flow-in port 8 of the uppermost stage and flows out through the discharge port 9 so as to flow in the influx port, which opens beneath the discharge pipe 9, of the hollow pipe of the next stage. Thus, the liquid resin flows out of the discharge port of the lowermost stage down in a resin tank 10 so as to be fed through a strainer 11 to the hollow pipe of the upper most stage for circulation by means of a pump 4. |
