Abstract: A coating method for forming a plurality of layers over a continuously traveling band-shaped substrate, including the steps of: forming a lower layer by coating a first coating liquid, and forming an upper layer over the lower layer by coating a second coating liquid including a composition substantially identical to or different from a composition of the first coating liquid; and applying an undercoating liquid to an uncoated portion before coating the second coating liquid when the uncoated portion is generated during forming the lower layer.

Abstract: A method for cleaning a web-like object to be cleaned, comprising the steps of: a cleaning solution spraying step for spraying a cleaning solution to a surface of a fed web-like object to be cleaned; and a cleaning solution removing step for removing the liquid film left on the surface of the object to be cleaned by ejecting a gas so that at least an ejected gas flow is formed in a direction opposite to the feeding direction of the object to be cleaned, wherein among the air induced by the gas ejection, the air induced from the side of the cleaning solution spraying position to the side of the gas ejection position is shielded.

Abstract: A coating apparatus comprising a forward bar, a liquid feed passage and a metering device for a coating liquid. The forward bar rotates about its axis in the same direction as the traveling direction of a continuously traveling band-shaped web while touching the web. When coating the web with the coating liquid, the liquid feed passage feeds the coating liquid to an area between the upstream side of the forward bar and the web with respect to the traveling direction of the web. The metering device is arranged on the downstream side of the forward bar for metering the coating liquid to a predetermined coating thickness as applied to the web by the forward bar.

Abstract: A coated film drying method for drying a film which is coated on a surface of a web while the web is running through a tunnel-shaped dry case having a web entrance and a web exit, comprising the steps of: blowing dry air toward a surface of the coated film through an outlet port which is provided with a porous distributor; and sucking the dry air through an inlet port which is disposed at a position downstream or upstream of the position where the dry air is blown out and on the same side as that on which the outlet port is disposed relative to the coated film, so that a stream of the dry air which flows in a direction parallel to the running direction of the web is formed across the entire width of the surface of the coated film.
