Open the CIPO recordAbstract From the Canadian patent
A web coating apparatus is disclosed in which the coating material is smoothed onto and excess coating material is removed from the web by a downstream blade comprising a metalic layer and a compressible layer on its upstream side. Longer wear of the blade is achieved by the fact that the compressible layer preserves a wedge of coating material adjacent the web even after the distal end of the metalic layer has become worn.
