<P>PROBLEM TO BE SOLVED: To provide a method for controlling a high-pressure spray coating apparatus which can regulate the weight and profile of a coating agent coated onto a web. <P>SOLUTION: In this controlling method, a web treating agent is sprayed from high-pressure spray nozzles 6, 21, directed to a web 1 being moved, onto the web. The amount of the web treating agent deposited onto the web is measured. When the measured value deviates from a predetermine set value, the flow rate of the treating agent on a solid mass basis passed through the spray nozzles is changed to regulate the amount of the web treating agent fed. In another embodiment, a spray jet of the treating agent, that has been atomized in a space which faces a passage of the web being moved, is discharged on the web. Suction is applied to the space in its lower end edge region to remove mist from the space, and the pressure of a suction chamber is controlled for the negative pressure of the suction chamber and the pressure of the above space. In a further embodiment, an air jet is blown from the space. In this case, the pressure of the air jet is controlled to prevent a stray mist from going out from the space. <P>COPYRIGHT: (C)2004,JPO |
