METHOD AND APPARATUS FOR VARYING INK FLOW BY DIFFERENTIAL ADJUSTMENT OF AN INK METERING BLADE AT INDIVIDUAL LOCATIONS ALONG ITS LENGTH, OR OF INDIVIDUAL INK METERING ELEMENTS, IN A PRINTING MACHINE INKING MECHANISM

摘要

AbstractA method and apparatus for varying the flow of inkby differential adjustment at individual adjustment locationsalong the length of an ink metering device of a printing machineinking mechanism by a plurality of adjusting devices such ascontrol motors, stepping mechanisms or the like, which areadjustable to differing extents by electronic control devicesin accordance with variations in reference value presettingswhich are the same for all individually adjustable adjustmentlocations, using reference value-real value comparators whichcause actuation of the adjusting devices, in which a referencevalue memory is provided for each adjusting device, and uponinput of reference value variations the values of all referencevalue memories are multiplied by a selected predeterminedreference value variation factor and the products of the multi-plication are transmitted as new reference values to thereference value-real value comparator.
