Profiling bar for a web coating device

摘要

A metering device for use in a coating apparatus for coating a moving web running over a backing member wherein the metering device includes a metering blade having an edge disposed in close proximity to the web and a profiling device for selectively changing the profile of the blade edge. The profile bar is joined to a plurality of adjustment actuators by bar limiter elements that are mechanically interlocked such that the movement of each limiter element relative to an adjacent limiter element in the direction of bar deformation is limited to a maximum distance. The edges of adjacent limiter elements are provided with interfitted projections and slots with sufficient clearance to permit only limited relative movement of adjacent limiter elements.
