Abstract: A sheet printing station is arranged between a sheet pick-up station and a sheet discharge station. A plurality of linear motors is provided, including electrically conductive rails which constitute the stators of the motors and are mounted at opposite lateral sides of the stations. Each of the rails form an endless loop which connects all of the stations. One or more carriages are mounted on the rails for travel along the same and constitute the armature of the respective motors. Sheet grippers are arranged on the carriage or carriages, and a control arrangement controls the travel of the carriage or carriages along the rails.
