    Abstract: Doctoring apparatus for doctoring a moving work surface is disclosed as including novel extended-life blade structures and combined therewith blade holding apparatus for supporting a blade for engagement with the work surface including means acting on the blade differentially along the length thereof to cause the blade to conform to deviations in the work surface. Blade holding apparatus is disclosed which minimizes the width-wise deflection of a supported blade and thus maximizes its length-wise flexibility. Extended-life blade embodiments are disclosed which include means defining on an end surface of a tip portion of the blade a narrow relatively wear-susceptible land having along one side thereof a leading edge for making initial line contact with a work surface, and a relatively wear-resistant structure adjacent the land on the side thereof opposite the leading edge. Upon contacting a work surface, the land wear relatively rapidly to break in the blade before contact is made between the wearresistant structure and the work surface, the wear-resistant structure wearing thereafter relatively slowly.

    Abstract: The disclosure shows self-adjusting doctor blades pivotally mounted in a blade holder. The blade can adjust itself in position relative to a work surface. The blade can also flex about a pivotal stop thereby minimizing or eliminating edge ripple at the leading edge.
