The rotary screen printing machine has a form cylinder (1) which carries a screen printing stencil (3), and an impression cylinder (2) having at least one cylinder pit (4), in which sheet grippers (5) are installed. In their closing position, the sheet grippers (5) do not project above the printing surface of the impression cylinder (2). Arranged inside the form cylinder (1) is an adjustable doctor (6) which can be controlled by an actuating mechanism (7, 8, 9) in such a way that, during a printing operation, the doctor (6) is pressed against the inside of the screen printing stencil (3), but is lifted off from this screen printing stencil when the open region of a cylinder pit (4) of the impression cylinder (2) passes the form cylinder (1).
