Abstract

An inking device for printing machines has an inking roller, an inking blade extending along an axial length of the roller, a plurality of adjusting members each displacing a respective portion of the inking blade to adjust the gap between the same and the inking roller, and two abutments against which all adjusting members can alternately abut to provide for maximum or minimum gap.

Claims3

Dependent claims

An inking device for printing machines, comprising

an inking roller having an axis and a predetermined axial length;
an inking blade extending over substantially the entire length of said inking roller and having an edge displaceable relative to said inking roller so that a gap between said edge of said inking blade and said inking roller can be changed in a plurality of locations spaced from one another in an axial direction;
a frame member arranged to support said inking blade so that said inking blade is fixedly connected with said frame member;
a plurality of adjusting members each arranged in the region of a respective one of said locations and displaceable so as to displace said edge of said inking blade at the respective locations and thereby adjust the gap at these locations;
and
reference means including two abutments spaced from one another and arranged so that when all said adjusting members simultaneously abut against one of said abutments the gap is minimum at all said locations along substantially the entire length of said inking roller, and when all said adjusting members simultaneously abut against the other of said abutments the gap is maximum at all said locations along substantially the entire length of said inking roller, each of said abutments being formed as a substantially plate-like member attached to said frame member at a distance from one another in the direction of displacement of said adjusting members and extending substantially normal to said direction, one of said plate-shaped members having a projecting lateral part extending in said direction and abutting against the other of said plate-shaped members so as to form a compartment therebetween, each of said adjusting members including an elongated threaded part extending in said direction and having one end arranged to press against said inking blade at a respective one of said locations and a transverse part extending substantially normal to said direction and parallel to said plate-shaped members and displaceable inside said compartment formed by said plate-shaped members so as to abut against one or the other of said plate-shaped members.
