Abstract
To prevent escape of ink from a gap (A) between the edge surface (11) of a side wall portion (10) facing a printing machine roller (9) and the surface of the roller, the side wall (3), or at least the side wall portion, is upwardly, outwardly inclined, so that internal flow of printing ink within the chamber, upon rotation of the roller, will result in a resultant flow speed vector (V.sub.res) which is inclined at an angle (.beta.) which is less than the angle of inclination (.alpha.) of the side wall, and thereby push liquid away from the side wall and hence from said gap (A).
