Vorrichtung zur Kontrolle der Oberflaeche einer Walzwerkwalze

EP 697591 A UPAB: 19960322 The sheet (3) rolling mill has a lower support roller (1) and a lower working roller (2). An elbowed arm (6) pivots about a bearing (5,7) and carries a scraper (8) in jaws (9) at it's extremity. The scraper (8) remains in normal contact with the working roller (2) even when it is worn. A water-tight box (12) contains inspection camera, such as a CCD camera, to inspect the surface of the working roller (2). The box (12) is carried underneath the scraper (8) and is small enough to avoid contact with the water jets (11). A semi-rigid sleeve (13) protects the camera head from accidental damage. ADVANTAGE - Roller surface may be inspected without stopping mill or disturbing cooling and lubrication.
