Abstract
A dyestuff applicator, overlying an area of a movable printing screen through which dyestuff is to be fed to a substrate, comprises a horizontal supply tube which supports an axially extending dyestuff-distributing member with freedom of relative movement in a vertical axial plane of the tube. The distributing member, resting under pressure on the screen, 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 a slidable or rotatable shutter lodged in the distributing member and controlled by an external actuator mounted on the supply tube.
