Abstract
Abstract A metering blade for zonally metering a liquid film comprises a plate body having a working edge usable in an arrangement in which the setting member bears against the plate body and bridges a portion thereof against a rotating roller comprises a blade with a plurality of zonal setting portions of a material capable of being displaced by resilient flection adapted to be arranged adjacent a setting member which includes intermediate portions between a working edge and the opposite edge compensating for the setting wherein the setting portions are at least 3 mm in thickness and each intermediate portion includes a web part having a thickness which is not more than 1/5th the thickness of the setting portion and has a width amounting to at least five times the thickness of the web. The blade has a working edge with a reinforcement adjacent each web.

A metering blade for zonally metering a liquid film on a rotatiang roller in inking coating and dampening devices of printing machines which is usable with a displaceable setting member which is adapted to bear against the blade adjacent a working edge thereof to position this edge in relationship to the rotating roller, comprising a blade body (1) having the working edge (5, 5a) and an opposite holding edge and having a plurality of alternately arranged resilient setting portions (3) and intermediate portions extending along its length, said setting portions each having a thickness of at least 3 mm, said intermediate portions each including a bottom comprising a thin web (8) having a thickness at most 1/5th the thickness of said setting portions and a width in a longitudinal direction amounting to at least five times the thicknesss of said web, and a reinforcement (9) defined adjacent said working edge intermediate the width of said web, said blade being made of a single piece of metal, said blade body being in the form of a flat plate, said intermediate portions formed as elongated rectangular recesses in a surface of said flat plate adapted to face away from the rotating roller, said setting portions being rectangular in said surface and being defined between said recesses and having a width equal to the width of said reinforcement for each intermediate portion, each reinforcement comprising a rectangular raised portion on said web of each intermediate portion and having rectangular sides spaced away from a setting portion on each side and a rectangular end extending to said working edge, a length of said sides of said reinforcement being less than a width of said recess between a setting portion on each side of said recess.

253 words
A metering blade comprising: a flat plate (1) having a working edge (5,5a) and an opposite holding edge; said flat) plate having a thickness of at least 3 mm, with a first surface adapted to face a rotating roller for metering a liquid film on the rotating roller, and an opposite second surface; said flat plate including, on said second surface thereof, a plurality of spaced apart rectangular recesses (4) defining setting portions (3) therebetween and having a thin web floor (8) extending across said first surface, each recess being elongated and extending away from said working edge (5,5a); a raised reinforcement portion (9) having rectangular sides and disposed in each recess and having a thickness equal to each setting portion and spaced from each setting portion so that a portion of said web in each recess extends between said reinforcement portion and each setting portion, each reinforcment portion having a top surface lying in said second surface of said flat plate and an outer side extending to a portion (5a) of said working edge, each reinforcement portion having a length in a direction of elongation of each recess which is less than a width of each recess perpendicular to said direction; and said web having a thickness at most 1/5th the thickness of said setting portions and a width of each recess being at least five times the thickness of said web; said flat plate with said recesses, setting portions, reinforcement portions and webs being made of a single piece of material.
