ABSTRACT:
According to the drying method and apparatus of the present invention, at first, the coated film on one end side of the support is more quickly dried than that on the other end side, because drying air is supplied from one end side of the support. Subsequently, the coated film on the other end side of the support is more quickly dried than that on one end side, because drying air is supplied from the other end side of the support. Accordingly, the method and the apparatus can diminish a difference between drying rates in on one end side and in the other end side of the long support, in the whole drying zone. Thus, the method and the apparatus can uniformly dry the support and inhibit the production of a dry spot.
