摘要：

A coating apparatus for coating a continuous roll of substrate (31), for example steel or aluminium in sheet-like form, includes an enclosed reservoir (34) which contains coating material under pressure. The enclose reservoir (34) is mounted in close proximity to an engraved roller (36) and coating material is applied from the enclosed reservoir (34) under pressure onto the surface of the engraved roller (36). The coating material is then transferred from the engraved roller (34) to an application roller (37) which then applies the coating material to the surface of the substrate (31). The application of coating under pressure onto the engraved roller (34) reduces coating wastage and the use of the engraved roller (34) ensures accurate application and removes the necessity for constant monitoring of the gap betwen the roller (34) and the roller (37).
