Abstract
A dyestuff applicator, overlying an area of contact between a movable printing screen and a substrate, comprises a horizontal supply tube which supports an axially extending dyestuff-distributing member with freedom of relative mobility in a vertical axial plane of the tube. The bottom portion of the distributing member, forming an axially extending dyestuff outlet in the shape of a slot or a multiplicity of closely spaced apertures, is separated from its top portion, secured to the tube, by a bar-shaped body of relatively soft material which is readily compressible in the vertical direction while resisting deformation in a horizontal plane. The distributing member is weighted down by the pressure of the liquid dyestuff in a overlying space or by springs inserted between that member and the supply tube.
