Abstract

PURPOSE:To expand the sleeve, to fix the movable sleeve, and to greatly increase the capacity of shape control for the strip, etc., the transferring the mandrel in the axial direction. CONSTITUTION:The hydraulic pressure is supplied into the shaft hole from the external hydraulic circuit through the rotary joint 4 and the through hole 101, and the mandrel 11 is transferred to the left side in the axial direction. As a result of this movement, the sleeve 12 expands outward in the radial direction. The movable sleeve 13 is attached to the outer surface of the sleeve 12 so to be movable in the axial direction; this movable sleeve 13 is fixed by the radial expansion of the sleeve 12. In contrast with this, by supplying hydraulic pressure into the shaft hole 100 of the bearing so as to transfer the mandrel 11 to the right side, the sleeve 12 contracts, and the movable sleeve 12 becomes movable in the axial direction.
