PROBLEM TO BE SOLVED: To smoothly reciprocate a shutter by providing, on the shutter, a seal liner having a wear resistant surface on the side to slid on a support member. SOLUTION: A shutter 3 provided in such a manner that the end part adjacent to the coated surface of an Al foil 15 is contactable with and separable from a doctor blade 7 so as to slid on a support member 5 has a pair of seal liners 3a fixed on both sides opposed to the support member 5 of a shutter member 3b in the center part and having a wear resistant surface on the side to slid. Since the liners 3a can be prevented from being flawed or galled even if fine particles in a coating agent 17 penetrate into the sliding part between the liners 3a and the support member 5 by the reciprocation of the shutter 3 followed by solidification, the shutter 3 can be normally smoothly moved to perform the supply of the coating agent 17. Further, since the seal liners 3a are wear resistant, the operability or durability of the device can be improved. |
