Abstract: This invention relates to a doctor blade assembly which is an improvement of the assembly as taught in U.S. Pat. No. 3,859,690, as well as to an improved pressure finger which can be used in the assembly. The improved finger includes a bearing part on which the finger can be pivotably mounted. Extending forwardly of the bearing part are two spaced apart jaws having inner facing surfaces which define, between them, mounting slots for the doctor blade. The inner surfaces comprise a plurality of parallel, spaced, transverse grooves, with respective ones of the grooves in one surface being aligned with respective ones of the grooves in the other surfaces. The aligned grooves form vertical sets of grooves, and all fingers on the assembly are disposed so that respective sets of one finger are aligned with respective sets in all other fingers to define a plurality of transverse channels or passages.

Abstract: A pressure finger for doctor blade assemblies is reduced in bulk and weight and deflection of a jaw of the finger which is attached to a pressure plate is avoided by the provision of at least one upstanding elongated, symmetrically arranged stiffening flange.
