Roll 13 drives base material 12 run continuously, and nozzle 1 applies paint 11 supplied by head 2 on base material intermittently. Head 2 shuts the flow of paint 11 to nozzle 1, when application of paint 11 is suspended, and guides to a place other than nozzle 1, at the same time sucks paint 11 staying in the inside of nozzle 1 and at the exit of slit 7 to sucking part 25 provided in inside of nozzle 1; when application of paint 11 is resumed, releases the flow of paint 11 to nozzle 1, at the same time returns paint 11 that was sucked in sucking part 25 to the inside of nozzle 1; thereby the starting edge and the ending edge of coated areas intermittently applied on the base material can be made to assume a straight line shape, and occurrence of the thicker coating at the starting edge is also prevented. |
