ABSTRACT:
A device for adjusting an ink knife relative to a ductor roller in an ink-applicator of a printing machine is disclosed. The device includes an number of adjusting arrangements arranged lengthwise of the ductor roller to control a plurality of ink zones along the length of the roller, each arrangement including a pivotable lever actuated to move a stripped edge of the ink knife to and from the ductor roller, and a tension spring extended somewhat normally to the ink knife and between the ink knife and a supporting element rigidly connected to the housing of the ink applicator, the tension spring locking the lever in its selected adjusted position. The device substantially reduces mutual influence of adjacent ink zones on each other during the adjusting operation.
