Abstract

A rolling roll train of the staggered-roll tandem type has a pair of upright stand walls with windows or openings for receiving a multiplicity of pairs of rolls which can be changed as a unit. The fact that unitary walls with traverses between the walls for stabilizing them and where those traverses are located between the roll pairs, enables the spacing between the roll pairs to be substantially reduced by comparison with free-standing individual mill stands for the roll pairs.
