ROLLING MILL ABSTRACT OF THE DISCLOSURE A rolling mill is disclosed wherein at least two drive rolls are mounted for rotation within a frame, with each drive roll being rotatably supported by at least one backing roll and at least one working roll is mounted for rotation between the drive rolls to define at least one path for passage of material to be rolled. While each working roll is freely rotating, it is rotatably driven by surface friction produced by engagement with at least one of the drive rolls. Each working roll has a diameter less than the diameter of the drive rolls and the mount- ing position is such that the rotational axis of each working roll is substantially in the same working plane as the rotational axis of the drive rolls while lateral support devices, preferably in the form of hydraulic medium operated piston members, act in engagement with the surface of each working roll to prevent movements of the working roll out of the working plane. In a preferred embodiment two working rolls are provided and define one material rolling path, while lateral support devices are provided to maintain the aligned position of the drive rolls as well as each working roll.
