APPARATUS FOR CONTROLLING MOVING DIRECTION OF ANNULAR BAND METHOD FOR CONTROLLING MOVING DIRECTION OF ANNULAR BAND CASTING FACILITY AND SOLUTION FILM FORMING METHOD

摘要

The annular flexible band 26 is wound on the horizontal rollers 24 and 25 in a tensioned state. The horizontal roller 24 is rotated by the motor 24M. The flexible band 26 circularly moves the traveling path formed around the horizontal rollers 24 and 25. Between the horizontal roller 24 and the horizontal roller 25 there are disposed a band one end temperature control unit 61P for cooling one end of the flexible band 26 in the Y direction and a band one end temperature control unit 61P for cooling the other end of the flexible band 26 in the Y direction And the other-end temperature control unit 61Q is provided. The control unit detects the direction in which the flexible band 26 deviates from the traveling path by the deviation direction determination section. Further, the control unit preferentially cools the end of the flexible band 26 in the direction away from the traveling path over the end of the flexible band 26 in the direction opposite to the off-direction.
