Abstract

A resilient metering blade (18C-E) is disposed downstream relative to the application of coating material onto a web (10C-E), e.g. paper. The blade (18C-E) includes a metallic layer (50) having a distal end (52) disposed adjacent to the web (10C-E) and a compressible layer (54), e.g. rubber which is disposed contiguously and upstream relative to the metallic layer (50). The compressible layer (54) has a distal end (56) such that during use of the apparatus (14D, E), as the distal end (52) of the metallic layer (50) wears away, the distal end (56) of the compressible layer (54) is compressed by the coating so that a wedge (38C) of the coating is disposed between the web (10C-E) and the blade (18C-E) thereby maintaining a smooth application of the coating onto the web (10C-E) and a prolonging of the life of the blade (18C-E).
