<p>Successive roll stands (10, 12) in a rolling mill are driven at selectively different drive speed ratios by a transmission system having a pair of drive shafts (22) and at least one idle shaft (24) journalled for rotation about parallel axes. First and second gear trains each include intermeshed drive gears (G1, G2, G4, G5) freely rotatable on the drive shafts, and a pair of idler gears (G3, G6) on the idler shaft; each being in meshed engagement with at least one of the drive gears of each drive train. Clutches (34) operated to selectively couple the drive gears of the first and second drive trains with their respective drive shafts. <IMAGE></p> |
