Abstract
A strip rolling mill of cluster type has, on at least one side of the strip path, a work roll, a plurality of intermediate rolls supporting said work roll and a plurality of backing bearing assemblies supporting said intermediate rolls. Each backing bearing assembly has a row of backing bearing units and shape control means by which the backing bearing units are adjustable relative to the work roll axis so that strip shape control can be applied. All backing bearing assemblies on one side of the strip path have such shape control means. In the mill at least two of the shape control means are independently operable so as to apply respectively different shape control patterns to the work roll.
