Patent attributes
A rotary press is capable of interchanging printing cylinders in a short time with less labor. The rotary press includes a first supporting device for supporting one end of a printing cylinder. The first supporting device is provided in a movable frame arranged outside a first side frame. A second supporting device, for supporting the other end portion of the printing cylinder, is provided in a second side frame. The movable frame is moved in an axial direction of the printing cylinder with respect to the first side frame by a first frame-moving device, whereby the first supporting device is attached on or detached from the one end portion of the printing cylinder. With the first supporting device detached from the one end portion of the printing cylinder by axial movement of the movable frame, the movable frame is further moved with respect to the first side frame by a second frame-moving device.
