Abstract:
A method of coating a photosensitive material with a coating solution, the method comprising the steps of:locating an application roller at least partially within a solution tray of a coating apparatus, wherein a wall having a metering blade extending therefrom is provided in said tray, such that said metering blade extends to a surface of said application roller, and said wall and said metering blade are positioned in said tray so as to divide the tray into a first section and a second section which is separate from said first section and defines a spill-over basin; supplying a coating solution to said first section of said solution tray such that said application roller is partially submerged in said coating solution; metering the coating solution on said application roller with said metering blade, as said application roller is rotated while being at least partially submerged in said coating solution; passing a photosensitive material through a nip between said application roller and a drive roller, said nip being downstream of said metering blade with respect to a direction of rotation of said application roller, such that the coating solution is applied to a surface of said photosensitive material as said photosensitive material passes through said nip; and catching coating solution from said first section which passes over said metering blade in said spill-over basin defined by the second section of said solution tray.
