Abstract (en)

[origin: EP0127590A1] A roll (1) for a strip-metal rolling mill stand, in particular a backing roll for a four-high stand, comprises a cylindrical shell (8a)covering a central zone (9) of the core (8) of thr roll, and at least one pair of expansion rings (12) which have outer cylindrical walls. The expansion rings (12) are mounted coaxially on the core (8) at opposite ends of the shell (8a) and lie substantially in contact with the shell (8a) in an axial sense. Each ring (12) can be expanded to the diameter of the shell (8a) by supplying pressurised fluid into an annular chamber (13) formed between each ring (12) and the core (8). By selective expansion of the rings (12) the operative width of the roll (1) can be adapted to the width of strip being rolled.
