Abstract
Adjustable width rolls are preferably used for rolling, for example, insides of H-beams of various sizes without exchanging horizontal rolls of a rolling mill. Each of the adjustable width rolls includes a roll shaft rotatably and axially movably supported relative to the rolling mill, and axially adjustable sleeve roll fixed to the roll shaft, and an axially stationary sleeve roll mounted on the roll shaft to be axially slidable but against rotatable relatively to the roll shaft. The adjustable width roll further includes an axially adjustable roll fixedly supported by the axially adjustable sleeve roll to form substantially one half of a rolling barrel of the adjustable width roll, an axially stationary roll fixedly supported by the axially stationary sleeve roll to form substantially the remaining half of the rolling barrel of the adjustable width roll, and a driving mechanism for driving the roll shaft in axial directions of the roll shaft.
