  • Patent number: 4023486
    Abstract: Improved squeegee apparatus for screen printing of carpets and other materials. A reservoir for receiving printing liquid is supported in spaced apart relation with a printing screen having a perforated pattern design therein. A squeegee head having screen-contacting sealing members is suspended from the reservoir with a flexible interconnection allowing the squeegee to ride along the screen surface, as the screen and the squeegee head undergo relative movement during printing. The squeegee head is provided with pressure reactive surfaces which adjust the screen-engaging force of the squeegee head, and also the sealing of the sealing surfaces, in response to pressure of the printing liquid in the reservoir. The present squeegee apparatus is especially useful for rotary screen printing of carpets.
