Abstract
In order to provide good sealing for an ink fountain insert installed in a wedge-shaped ink fountain, the base of the insert is lengthened at its lower end by a resilient strip by which the insert can be arranged on the ink blade, and the side walls of the insert support a resilient wedge in the deflecting area of the strip.

An insert for an ink fountain of a printing machine, which ink fountain includes an ink blade, a blade rail and an ink fountain roller, the insert comprising:
- a base having a lower end;
- side walls each having a forward end shaped to compliment the ink fountain roller;
- a resilient strip that extends from the lower end of the base so as to facilitate placement of the insert on the ink blade of the ink fountain, and so that a portion of the strip can deflect;
