Abstract
A dyestuff applicator for an apertured printing screen, curved about a horizontal axis, comprises an axially extending supply tube within an elongate casing supported thereon, the open casing bottom being surrounded by flanges in clamping engagement with an elastic membrane curving downwardly toward the underlying screen surface under pressure of the overlying liquid and of a limitedly vertically movable loading frame. A metallic foil, curved cylindrically about the screen axis, is interposed between the membrane and the screen, the foil and the membrane being provided with aligned openings which form an outlet for the dyestuff liquid along a median zone of contact bracketed by the frame.
