Abstract (en)

The machine for the production or finishing of paper, tissue or cardboard. from a pulp, has at least one marking unit (9) to apply at least two marks to the web (1), with a longitudinal gap between them in the direction of web travel. A monitor (10) is after the marking unit, to measure the space between the marks by scanning without contact. The marking unit is at the fourdrinier or the press section. A further monitor is at a roller (13), as a rotary transmitter (14) or trigger, which measures moving web lengths especially as an encoder or a drive signal meter. A control (15) compares the signals from the two monitors, linked to an evaluation unit (21) which is connected to a further control (20) with an off-line processor (16).
