Abstract
Abstract Apparatus for controlling a color dosing device in relation to a color doctor roller wherein the entire color dosing device, under retention of the support line between the color knife and the color profile lever is pivotable about a fulcrum point for the purpose of setting the color slot, characterized in that for the purpose of changing the blade angle or clearance the entire color dosing device is pivoted about the fulcrum point without changing the color slot and the fulcrum point is shifted a distance corresponding to the change in the color slot whereby the individual color profile levers which act on the edge of a color knife are separately pivoted for setting the color profile and all of the color profile levers are jointing pivoted for parallel setting of the color knife and color profile storage.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
In a sheet fed printing press, an automatic control device for controlling color dosing means in relation to a color doctor roller wherein for setting of the color slot the entire color device is mounted for pivoting movement about a fulcrum under retention of the support line between the color knife and color profile levers, said color dosing means being pivotally mounted for pivoting of said entire color dosing means on pivotable eccentrics, said eccentrics being mounted on a traverse, the eccentricity of said eccentrics being proportional in direction and amount to the change of the color slot resulting from any change in operational setting angle, color profile levers being operatively associAted with the edge of said color knife, said color profile levers being provided with first impact surfaces, color zone screws adapted for striking said first impact surfaces of said color profile levers, said color profile levers having second impact surfaces, storage bar means mounted for movement perpendicular to said second impact surfaces and storage screws for said storage bar, said storage bar being adapted for movement by said storage screws for striking said second impact surfaces of said color profile levers.
