Abstract: A screen printing press employs a screen carriage securing a printing screen frame and screen therein and which reciprocates through print and return strokes over a reciprocally rotating print cylinder. Printing stock is advanced between the print cylinder and the screen during printing strokes. The screen carriage includes a disengageable drive which permits feeding print stock through the machine without effecting printing thereon. The screen carriage further includes adjustable screen frame holding means to which the screen frame is slidably mounted permitting partial or total removal of the screen frame from the screen carriage. A fully adjustable squeegee means and flow coater assembly is positioned above the screen and is provided for elevating and longitudinally shifting the flow coater and squeegee assembly away from the printing area for inspection and maintenance of the press.
