Abstract
Abstract To transfer ink from an ink trough (2, 3) to an ink receiving roller (1), the ink is transferred in the form of axially adjacent rings or circumferential strips of ink. The rings or strips of ink are generated by placing two superposed plates (4, 5), each having front edges (A, B) with recesses or notches (16, 18) therein, the ink flowing through the notches. The width of the ink strips is controlled by axially shifting one of the plates (5) with respect to the other (4) by engagement of the shiftable plates with an eccenter (11-14). The transferred circumferential strips or rings are then milled in the standard milling roller arrangement of printing machine inkers.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
193 words
Inker for a rotary printing machine having an ink trough (2); an ink receiving roller (1) positioned to receive ink from the ink trough; and a plurality of ink metering elements located axially adjacent each other and positionable against the ink receiving roller (1) to control ink flow from the trough to the surface of the roller, wherein, in accordance with the invention, the ink metering elements comprise two superposed plates (4, 5), each having a resilient front edge (A, B) formed with at least approximately matching recesses or notches (18, 16), said resilient front edges (A, B) engaging the surface of the ink receiving roller (1) so that, at the location of the recesses or notches, ink will be permitted to flow to the roller (1) and coat the roller in circular strips or rings of ink; and means (11, 12, 13, 14) for axially shifting one plate (5) with respect to the other (4) to thereby change the relative position of the recesses or notches of said plates with respect to each other, and thereby control the width of the circular strips or rings of ink being applied to the roller.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
50 words
Inker according to claim 1, wherein the means for axially shifting one of the plates with respect to the other comprises a reduction gearing (12) and an eccenter (11) driven by the reduction gearing, and an elongated opening (15) formed in said one plate, and engaged by the eccenter (11).
Claim 4
Dependent Claim
29 words
Inker according to claim 1, wherein a plurality of recesses or notches (16, 18) are formed at the front edges (A, B) of each of the plates (4, 5).
Claim 5
Dependent Claim
13 words
Inker according to claim 3, wherein the notches are of essentially rectangular configuration.
Claim 6
Dependent Claim
15 words
Inker according to claim 1, wherein said recesses or notches are of essentially rectangular configuration.
Claim 7
Dependent Claim
36 words
Inker according to claim 1, wherein one (4) of the plates (4,5) is axially secured to the ink trough (2, 3) and the axially shiftable plate (5) is located beneath said one (4) of the plates.
Claim 8
Dependent Claim
40 words
Inker according to claim 1, wherein the radial dimensions of the plates (4, 5) are different; and individual spring means (6, 9) are provided, engaging the respective plates and pressing the respective plates, essentially radially, against the ink roller (1).
Claim 9
Dependent Claim
47 words
Inker according to claim 1, wherein the axial width of said one plate (5) is axially shiftable corresponds to the width of an ink zone division; and the axial width of the other plate (4) has at least approximately the same width dimension as said one plate.
Claim 10
Dependent Claim
55 words
Inker according to claim 1 , wherein the axial width of said one plate which is axially shiftable corresponds to the width of an ink zone division; and the axial width of the other plate (4) has at least approximately the width of a whole number multiple of the width of said axially shiftable plate.
Claim 11
Dependent Claim
18 words
Inker according to claim 1, wherein said plates engage the roller (1) in at least approximately radial direction.
Claim 12
Dependent Claim
18 words
Inker according to claim 3, wherein said plates engage the roller (1) in at least approximately radial direction.
Claim 13
Dependent Claim
18 words
Inker according to claim 6, wherein said plates engage the roller (1) in at least approximately radial direction.
Claim 14
Dependent Claim
18 words
Inker according to claim 7, wherein said plates engage the roller (1) in at least approximately radial direction.
Claim 15
Dependent Claim
41 words
In combination with a printing machine, the inker of claim 1, wherein the recesses or notches (16, 18) of one of the plates (4) are positioned in the machine non-congruent with the recesses or notches of the other of the plates.
