    • PURPOSE:To avoid a phenomenon to accompany air to a lower pass roll and obtain a stable coating to improve production yield by forming grooves in a constant distance in the same direction of the film running direction in the lower pass roll. CONSTITUTION:Block-like lips 12 which are formed in and extruded from one side of a block-like die head nozzle main body, a paint storing part 13 formed in the center part of the die head nozzle main body 11, and a flowing groove 15 which communicates the paint storing part 13 and the tip parts of the lips 12 floatingly are installed. A lower pass roll 16b and an upper pass roll 16a are installed in the upper stream side and the down stream side, respectively, in the running direction of a film 14 which runs while touching the tip parts of the lips 12 and keeping a tensile force and grooves 21 in almost the same distance each other are formed in the lower pass roll 16b in the same direction as the film running direction. The following air 17 swallowed in the lower pass roll 16b is led to escape through the grooves 21 formed in the roll surface and the disorder of the pressure of the contacting planes of the film and the roll can be prevented.
