Abstract
A dyestuff applicator, located inside a cylindrical printing screen, comprises a horizontal ink tube which supports an axially extending ink-distributing member with freedom of relative mobility in a vertical axial plane of the tube. The distributing member, resting on the inner screen surface, forms a discharge slot communicating with the interior of the tube through a multiplicity of conduits closely spaced along the tube axis, the conduits being disconnectable from the slot with the aid of an axially slidable or rotatable shutter common to all the conduits and lodged in the distributing member. This distributing member is weighted down by the pressure of the ink in an overlying space, or by springs or fluid cushions inserted between that member and the tube.
