ABSTRACT A roll is disclosed which has a rotating hollow shell and a stationary transverse shaft running through the length of, and spaced annularly from the internal periphery of, the hollow shell. The space between the hollow shell and the transverse shaft forms a longitudinal chamber provided with a supply line for pressure fluid the said chamber being divided by a sealing arrangement comprising longitudinal seals in the form of strips running on both sides of the effective plane of the roll, and by transverse end seals. Each transverse end seal is in the form of a gap seal, the gap surfaces of which are kept apart by a separate precision roller bearing. The gap surfaces may be flat and run radially, or may be cylindrical.
