Abstract
A screen printing machine is provided which includes a frame, a backing member supported by the frame, and at least one rotary screen assembly carried by the frame. Each rotary screen assembly includes an inner elongated support member, an outer hollow screen rotatably supported about the inner elongated support member for rotation thereabout, and an elongated applicator, which may be a conventional squeegee, which engages the inner surface of the hollow screen and which is supported by the inner elongated support member located within the screen. A first drive is provided which is operatively connected with the backing member for rotating the backing member. A second drive is provided for rotating the hollow screen independently of said first drive and the backing member. In addition, a variable speed device is provided in association with said second drive, for varying the speed of rotation of the rotatable screen relative to the speed of rotation of the backing member in order to synchronize the linear velocity of each of the rotatable screen and backing member.
