Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a coating layer of a web by arranging a premeasuring treating lever having a specified dimensional diameter between a coating applicator and an air knife and allowing the web to contact with a lever surface over a specified angle range. SOLUTION: A coator system 9 is constituted by arranging the air knife 36 at a downstream of the coating applicator 12 and a premeasuring treating lever assembly 10 at an upstream of a supporting roll 38. The lever 26 extending to a cross machine direction is provided at the premeasuring treating lever assembly 10, and the diameter of the lever 26 is set within a range of about 1/4 to 3 inch. Then the web 16 passing through the coating applicator 12 is brought into contact with the lever 26 at an angle within the range of 3-40 deg.. This contact angle is regulated so that the coating material 24 has a desired and uniform thickness. The uniformly coated web 16 is subjected to a doctor treatment with the air knife 36. In this way, the coating thickness is reduced and the web speed passing the air knife is increased.
