  • Apparatus for and method of applying a pattern upon a substrate
    Patent number: 4433623
    Abstract: Silk-screening apparatus for applying a pattern on a substrate surface includes suction applying facilities for returning residual pattern forming medium back through a screen member to the upper surface thereof after a pattern has been applied. Means are provided for adjusting the magnitude of suction from a minimal value adjacent imperforate portions of the screen member to a substantially constant value adjacent perforated portions sufficient to draw the pattern-forming medium back to the upper surface. Means are provided for maintaining a substantially constant magnitude of suction as a suction applying member passes over perforated portions of the screen member having varying degrees of porosity.
