Abstract
A device for turning sheet-like material from a printed side onto an unprinted side uses an impression cylinder which guides the sheet-like material and which is preceded by a transfer cylinder and followed by a further transfer cylinder. The sheet-like, flexurally rigid material is received on the outer surface of the impression cylinder and can be printed with a transmission cylinder. In the gusset between the outer surfaces of the impression cylinder and the preceding transfer cylinder, a contactlessly acting throw-on device is provided which forces the sheet-like material into a curved position corresponding to the curvature of the outer surface of the impression cylinder such that the sheet-like material is curved even in the gusset region. A printing press and a multicolor rotary printing press are also provided.
