The side wall (5) for an ink fountain of a printing machine has two plates (11, 14) fixed some distance apart and an intermediate plate (13) having a front edge (13a) in the shape of an arc of a circle. This intermediate plate (3) is mounted between the plates in such a way that it can be shifted and tilted. The front edge of this plate contacts the circumference of an ink fountain roller (6) via springs (18, 19) acting on the intermediate plate. The wall has a slideway (10) in which the plates (11, 14, 13) are mounted. The slideway has a reinforced region (12) on one of its sides which is proximate the ink fountain roller (6). The side wall (5) thus more effectively seals an ink fountain against leakage. The blade at the bottom of the ink fountain is split into several adjacent sectors (111) that can be shifted so as to vary the distance between the edge (112) of the blade and the circumference of the ink fountain roller (6). The sectors (111) can be shifted in the plane of the blade, parallel to each other.
