Abstract

The device has a radiation transmitter (7) and a radiation receiver (9) which are allocated to at least one edge (8) of a paper web (5). The electromagnetic radiation emerging from the transmitter is directed onto a sensitive surface (11) of the radiation receiver, the paper web intersecting a ray path (10) within the sensitive surface of the receiver. A control device influencing the drive speed of the web-fed printing machine is connected downstream of the receiver. Before commencement of a roll-changing operation, the frequency and/or amplitude of a flutter movement of the expiring paper web are measured. The measured values are then fed to the aforementioned control device. The optimum machine speed is thus predetermined in the event of a paper roll exchange. <IMAGE>
