APPARATUS AND METHOD FOR COATING SHEET OR STRIP ARTICLES

摘要

A coating head, and coating apparatus and methods using the coating head, for applying a solvent free coating material to a strip article advancing longitudinally in a coating line. The head includes a die having a transverse slit through which the coating material is deposited on the strip surface and having a land portion with an extended land surface on the exit side of the slit, the die being supported for movement normal to the strip surface, and one or more air or hydraulic cylinders exerting a load on at least the land portion of the die to urge the land surface toward the strip, wherein the die is constituted of a main body and the land portion, and the land portion is so connected to the main die body as to be capable of flexing relative to the main die body in a direction normal to the strip surface but to resist flexing in the direction of strip advance in the coating line.
