An object is to provide a rotary press that copes with a variation in the positions of printing cylinders and that includes a safety device having a simple structure. The rotary press has a cut-off length of a web ( 11 ) that is variable by changing diameters of a plate cylinder ( 15 ) and a blanket cylinder ( 17 ), the rotary press including a printing section ( 6 ) including the plate cylinder ( 15 ) and the blanket cylinder ( 17 ); an ink-applying roller ( 20 ); and a safety device provided in the vicinity of the printing section ( 6 ). The safety device includes a safety bar mechanism ( 37 ) that stops the operation upon detecting intrusion of an object to a contact area of the plate cylinder ( 15 ) and the blanket cylinder ( 17 ) and/or a safety cover ( 30 ) that is provided to shield the plate cylinder ( 15 ), the ink roller ( 20 ) and the blanket cylinder ( 17 ), from the outside. The edge of the safety cover ( 30 ) and the safety bar mechanism ( 37 ) are movable to positions corresponding to the movement of the plate cylinder ( 15 ) and the blanket cylinder ( 17 ) due to changes in the diameters thereof.
