Abstract

PURPOSE:To give an appropriate correction quantity to a gap of each part of a T-die lip by controlling driving of driving machines each without causing them to interfere with each other, by a method wherein operation is performed through non-interferential control algorithm based on (n) pieces of feed back signals and (n) pieces of reference input signals, (n) pieces of command values deciding (n) pieces of driving quantities are put out, and (n) pieces of driving machines are driven, through which a gap quan tity of a gap part is controlled. CONSTITUTION:A film thickness measured value detecting part 10 measures film thickness values Z'1-Z'3... at (n) positions and an operation control part 11 performs reference input of (n) pieces of film thickness target values w1-w3... corresponding to the (n) positions of film thicknesses. Operation is performed through non- interferential control algorithm by receiving the measured film thickness values as main feedback signals and (n) pieces of command values e1-e3... are applied to an operation part 32. After amplification of the command value by an amplifier 13, (n) pieces of driving machines 4-1, 2, 3... are driven according to the command values and gap quantities Z1-Z3... of a gap part 5 are varied by performing pushing of a structure 2 at a point. As the gap quantity of the gap part 5 can be controlled swiftly and correctly, a film thickness can be formed at high accuracy.
