About a coating liquid layer S which has been formed on the base material K, a target amount, coating length, and coating width are detected, and feedback control of coating liquid supply amount control, timing adjustment control, and interval adjustment control is performed so as to the detected target amount, the detected coating length, and the detected coating width match their allowable range respectively.

Coating device and coating method

The system has an operation state detection unit (201) and an arithmetic unit (202) to determine the desired valve control time (To) of an inlet (17) or outlet (18) valve according to the operation state (D). A variable valve timing control mechanism (40) varies the valve control time. A control unit (24) for the actual valve control time generates a control value (i) for the valve timing control mechanism. A detection unit (203) detects the actual valve control time (Ta). The control unit (24) for the actual valve control time generates a control value (i) for the valve timing control mechanism, so that the actual valve control time equals the desired valve control time. An integral control unit (205) determines an integral correction value ( EPSILON Ki) by integrating the control time to correct the control value. An initialisation use of the machine operation state is detected, to initialise the integral correction value to an optimum value, which is matched to the operation state. The initialisation unit is arranged, so that an initial value of the integral correction value is a negative value.

PROBLEM TO BE SOLVED: To provide a slot die which is provided with a passageway that includes a transverse flow supplying manifold, a flow metering section that develops a transverse flow metering gap and an exit channel that includes an exit orifice. SOLUTION: When a slot die is in a first condition, the second die body and the third die body are non-adjustable, and when the slot die is in the second condition, the second die body and the third die body keep the position adjustable. Each has a moving shaft which determines a Z-axis of an X-Y-Z coordination system. The transverse flow metering gap of the flow metering section can be adjustable independently of the change in the gap of the exit orifice by moving at least one of the position adjustable die bodies along the Z-axis. The transverse flow metering gap can be selected independently of the change in gap or width of the gap of the exit orifice by using one or more of the die body which is normally non-adjustable.
