Abstract

The invention relates to a drive (51) and a method for operating a drive (51) of a rolling mill having a coiling machine. The drive (51) is provided for controlling the transport of a rolled material to the coiling machine by means of drive rollers (5, 53, 55) which are in contact with the rolled material. The drive (51) has a sensor unit (1) for detecting the surface structure of the drive roller (5, 53, 55). The sensor unit (1) comprises a sensor support (9) having a plurality of laser sensors (7) which are arranged to emit a diverging laser beam (23) towards the surfaces (54, 56) of the drive rollers (53, 55) and to receive the laser light (29). The driver (5) may have a control unit (11) for detecting the surface structure of the drive rollers (53, 55) on the basis of the reflected laser light (29). For removal, the sensor unit (1) is arranged to be removable from the drive (51) by means of a lifting device or to be laterally removable from the drive (51).
