Apparatus and method for coating elongated strip articles.

摘要

A coating head (22) having an open-sided slot to which coating material is supplied under pressure is used, and a support such as a roll (14) around which the strip (10) is advanced past the head (22) for receiving from the slot a layer of paint metered between the head (22) and the strip (10), wherein a load is continuously exerted on the head (22) during operation for urging the head (22) against the applied paint layer on the strip (10) so as to maintain a uniform metering gap between the head and the coated strip surface. The load may be exerted by devices such as air cylinders (56) acting on the head (22) and capable of adjustment to vary the magnitude of the load for different coating operations.
