Abstract (en)
[origin: US4477722A] In monitoring rod or wire rolling mills it is useful to determine whether the rolling and cooling trains are free of obstacles. To that end a light source and an optoelectric sensor are swivelled into the traveling line of the goods to be rolled and after measurement they are swivelled out of the traveling line. The measured data are supplied to a control unit to which also detectors (30, 31) for the traveling goods arranged in front of the supply end and/or behind the discharge end of the rolling train are connected.
