Abstract: A reel changer of a web-fed printing press includes a load-bearing axle and a carrying arm having at least two carrying-arm segments. A printing-material reel may be mounted or clamped between the carrying-arm segments of the carrying arm. The printing-material reel is displaceable relative to the load-bearing axle using the carrying-arm segments in a production mode. A control system and a safety system which operates independently of the control system both monitor the relative spacing between the carrying-arm segments and blocks the respective carrying-arm segments in the event of an impermissible spacing deviation in the production mode. The safety system includes a separate distance measuring device dedicated to each carrying-arm segment, which distance measuring devices interact with an evaluation device.

Abstract: A winding device for winding a material web into a roll includes a roll carrier with at least two driven roll support members which are each movable between a winding position and an exchange position, a transfer device and a contact pressure device. The roll support members can be driven in two different directions of rotation. A first material web path is provided at the end of which the material web travels in a first direction onto the roll and a second material web path is provided at the end of which the material web travels in a second direction onto the roll. The transfer device includes a first cutting device which is movable from a first side into the material web and a second cutting device which is movable from a second side into the material web.
