  • Apparatus for applying a flowable medium to a surface, especially a web, roll or the like
    Patent number: 5099758
    Abstract: In a screen printing apparatus an applicator body is rotatable about its axis to selectively bring one of a plurality of medium supply ducts into active position so that it can deliver the color medium to the substrate. The applicator roller or blade and a strip defining the applicator compartment are provided on the rotatable body for each set of orifices and each distribution duct so that these elements need not be cleaned for color changeover since they remain associated with the color when the applicator is rotated.
