A dyestuff applicator inside a cylindrical printing screen comprises an elongate hollow body with a bottom portion contacting the inner screen surface and an outlet for ink supplied to that body through one of two tubular extremities thereof, these extremities being clamped in respective mountings with their axes disaligned to generate stresses counteracting the forces of gravity and friction which tend to deform the outlet from its linear shape. Each end mounting may comprise a pair of axially spaced rigid rings with toroidal inner surfaces, of adjustable relative elevation, or an elongate sleeve cradled in a vertically adjustable bearing frame in which the sleeve can be immobilized at a desired inclination to the horizontal and the vertical. The sleeve may have a yieldable lining or be braced by damping springs and dashpots against oscillations of the applicator body. |
