Abstract
Abstract A device for the angular and axial setting of a printing machine cylinder which is axially displaceable by a control means comprises a pair of coaxial cylindrical pinions whose teeth are set at different angles, one pinion being solid with the cylinder and the other pinion being freely mounted relative thereto, engaged by a pinion assembly of the machine and coupled to the one pinion by a sliding friction coupling, the two pinions being engaged by a freely axially adjustable double pinion which provides an angular control and a link with the axial control.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
98 words
A device for the angular and axial setting of a printing machine cylinder which is axially displaceable by control means, the device comprising: a. two coaxial cylindrical pinions having teeth set at different angles, one of said pinions being solid with the cylinder and the other of said pinions being freely mounted relative thereto, b. a pinion assembly cooperating with said other cylindrical pinion, c. a freely axially adjustable double pinion cooperating with said two pinions and providing a control and a link with said axial control means, and d. a sliding coupling for coupling said two pinions.
Claim 2
Independent Claim
98 words
A device for the angular and axial setting of a printing machine cylinder which is axially displaceable by control means, the device comprising: a. two coaxial cylindrical pinions having teeth set at different angles, one of said pinions being solid with the cylinder and the other of said pinions being freely mounted relative thereto, b. a pinion assembly cooperating with said other cylindrical pinion, c. a freely axially adjustable double pinion cooperating with said two pinions and providing a control and a link with said axial control means, and d. a sliding coupling for coupling said two pinions.
Claim 3
Dependent Claim
38 words
The angular and axial setting device as claimed in claim 1, wherein the sliding coupling comprises at least one friction ring compressed between and acting against said two pinions by means of a member exerting an axial force.
Claim 4
Dependent Claim
28 words
The angular and axial setting device as claimed in claim 2, wherein said other pinion is axially free, and said two pinions are bolted to said friction ring.
Claim 5
Dependent Claim
46 words
The angular and axial setting device as claimed in claim 1, wherein the slidiNg coupling comprises at least one friction ring rotatable with one of said two pinions and applied against the other of said two pinions by at least one spring exerting an axial force.
Claim 6
Dependent Claim
21 words
The angular and axial setting device as claimed in claim 4, wherein the compressive force exerted by said spring is adjustable.
