A rotary screen printing press includes, a rotary screen cylinder which supports a screen printing form and is supported rotatably; an impression cylinder which is provided to oppose the rotary screen cylinder, and is supported rotatably; and a squeegee which is located within the rotary screen cylinder and, during printing, contacts an inner peripheral surface of the screen printing form, while being pressed against it, to transfer ink stored within the rotary screen cylinder to a material to be printed, which is held on the impression cylinder, via holes of the screen printing form. The printing press has a squeegee throw-on and throw-off control device which controls the pressing force of the squeegee acting on the inner peripheral surface of the screen printing form during printing in accordance with the type and thickness of the material to be printed.

In a safety device for ink forming rollers, each of the rollers is supported on a frame through a moving shaft movable in an axial direction to remove the ink forming roller, a safety pin is provided which is urged and supported on the frame, the moving shaft is formed with a recess for engagement with the safety pin and guide surface for guiding the safety pin to the recess against the urging force of the safety pin. When the ink forming roller is mounted, the safety pin automatically engages to interrupt movement of the moving shaft, thereby preventing the ink forming roller from falling down due to an external cause such as a power stoppage or a misoperation, and the safety device being prevented from careless locking failure, thereby improving the safety of the printing machine.
