Abstract
Abstract An apparatus for diagonal register adjustment of a plate cylinder and applicator rollers for printing presses, and in particular rotary cylinder offset printing presses, which comprises a plate cylinder including bearings. Each of the bearings of the plate cylinder having an additional rotatably movable eccentric bushing and the angular adjustment of the bushing setting the plate cylinder oblique to an offset cylinder. Means are provided for positively controlling applicator rollers not tangent to the adjustment arc. The eccentric bushing for the diagonal adjustment of the plate cylinder has a substantially axial groove, a pull-or push rod has a collar, and the latter is guided in the axial groove. A ring member has at least two arms, arranged loosely on the eccentric bushing between a wall and a safety ring fastened to the eccentric bushing. Angle pieces have threaded bores and the arms at their ends into the angle pieces. Movable spindles are provided for the fine adjustment of bearings of the applicator rollers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
250 words
An apparatus for diagonal register adjustment of a plate cylinder and applicator rollers for printing presses, and in particular rotary cylinder offset printing presses, comprising a machine wall, a plate cylinder mounted in bearings, and cooperating operatively with a rubber blanket cylinder, applicator roller for transferring ink to said plate cylinder, each of said bearings of said plate cylinder having an annularly rotatably movable eccentric bushing operatively disposed in said machine wall, angular adjustment of said bushing setting said plate cylinder oblique to said blanket cylinder, the eccentric bushing at an end of said plate cylinder having a substantially axial groove, a push-pull rod longitudinally disposed in said machine wall and having a collar, means for mounting and adjusting said rod for movement to adjust the oblique position of said plate cylinder, a portion of said collar being disposed substantially centrally of the ends of said eccentric bushing in said axial groove, a safety ring fastened to said eccentric bushing, a ring member having at least two substantially radially directed arms, mounted for relative movement on said eccentric bushing between said machine wall and said safety ring, said arms of said ring member being turned at their ends into angle pieces, the latter having threaded bores, movable spindle means for the fine adjustment of said applicator rollers being adjustably threadedly mounted in said threaded bores of said angle pieces and means for guiding the movement of said spindle means and thus the arms, upon displacement thereof by said eccentric bushing.
Claim 2
Independent Claim
250 words
An apparatus for diagonal register adjustment of a plate cylinder and applicator rollers for printing presses, and in particular rotary cylinder offset printing presses, comprising a machine wall, a plate cylinder mounted in bearings, and cooperating operatively with a rubber blanket cylinder, applicator roller for transferring ink to said plate cylinder, each of said bearings of said plate cylinder having an annularly rotatably movable eccentric bushing operatively disposed in said machine wall, angular adjustment of said bushing setting said plate cylinder oblique to said blanket cylinder, the eccentric bushing at an end of said plate cylinder having a substantially axial groove, a push-pull rod longitudinally disposed in said machine wall and having a collar, means for mounting and adjusting said rod for movement to adjust the oblique position of said plate cylinder, a portion of said collar being disposed substantially centrally of the ends of said eccentric bushing in said axial groove, a safety ring fastened to said eccentric bushing, a ring member having at least two substantially radially directed arms, mounted for relative movement on said eccentric bushing between said machine wall and said safety ring, said arms of said ring member being turned at their ends into angle pieces, the latter having threaded bores, movable spindle means for the fine adjustment of said applicator rollers being adjustably threadedly mounted in said threaded bores of said angle pieces and means for guiding the movement of said spindle means and thus the arms, upon displacement thereof by said eccentric bushing.
Claim 3
Dependent Claim
47 words
The apparatus, as set forth in claim 1, said means for guiding includes additional bearings disposed on said wall, said spindle means are guided in said additional bearings, and each of said movable spindle means has a collar at one end adjacent one of said applicator rollers.
Claim 4
Dependent Claim
31 words
The apparatus, as set forth in claim 2, wherein the cross-section of said collar of said push-pull rod substantially corresponds with the cross-section of the tooth of an involute-toothed spur gear.
Claim 5
Dependent Claim
51 words
The apparatus, as set forth in claim 1, wherein said machine wall has a first bore in which said push-pull rod is disposed, said machine wall has a second bore disposed cross-wise to said first bore, and a cylindrical bearing means recessed in said second bore for guiding said push-pull rod.
Claim 6
Dependent Claim
59 words
The apparatus, as set forth in claim 1, wherein said eccentric bushing is operatively disposed in said machine wall in a second bore of the latter, said axial groove is disposed substantially along a plane which bisects the center of the width of said second bore, and said push-pull rod is oriented substantially tangentially relative to said eccentric bushing.
