Abstract
Appts. for controlling the calibre of a strip in a tandem mill with a series of cages, so as to change the calibre as required at any point without stopping the rolling mill, comprises means for controlling the operating speed of the first cage, means responding to the movement of the strip for detecting the arrival of the point of calibre change in a second cage in order to produce a change of operational speed of the first cage with respect to its final pre-determined speed and the final pre-determined speed on the second cage after the passage of the calibre change point into the second cage mill. Enables greater productivity to be achieved by enabling large spools of strip to be processed continuously with pre-determined changes of strip thickness of any given length, or alternatively permits sections of strip of different thickness to be welded end to end and rolled to a continuous strip of uniform pre-determined thickness.
