ABSTRACT:
A knife designed as a flexible steel plate for the ink ducts of an offset printing machine has blades in the area of the working edge which can be bent differently in zones against an ink ductor by individually adjustable regulator elements. The multiple blade ink knife designed as an autonomous unit. It comprises two-part side jaws attached on both sides to a knife holder, each with an outer metal jaw and an inner plastic jaw which presses resiliently against the front of the ink ductor and the knife. This suitably has a groove, recessed at least in the area of the knife dipped into an ink bath, which is filled with an elastic sealant. At least the blades of a knife designed as a flexible metal plate, also an autonomous unit, are fully covered on the top with a flexible metal strip applied by adhesive.
