Abstract
899,544. Rolling. BRITISH ALUMINIUM CO. Ltd. Aug. 29, 1958 [Sept. 17, 1957], No 29275/57. Class 83 (4). [Also in Groups XXXV and XXXVIII] The shape of metal strip of sheet passed through a pair of rolls is controlled by measuring the difference between the radii of at least one of the rolls at at least two locations and modifying at least one of the controlling factors to compensate for the difference. Two cambered rolls 1 are each formed integrally with a shaft 2 carried in a frame 3 and the upper roll is movable towards the lower by screw members 4. The roller strip is taken up on a driven roller 7. Two measuring rollers 9 driven by the upper roll are subject to the variation in the roll radii produced by variation in the roll temperature and modify the roll camber by operating by electrical control means (see Group XXXV) a valve 11b which regulates an oil supply to feeding pipes 10a which spray portions of the upper roll to reduce its temperature and thereby adjust the radii. The drive of the roller 7 or of a screw-down motor for the rolls 1 may be controlled by the electrical means.
