Abstract

PURPOSE:To simplify the construction, and to greatly improve the facility of maintenance, by installing in parallel a disconnecting device for a roll from a driver and a slide mechanism for reducing the resistance to axial movement of a roll. CONSTITUTION:A frame 32 of a roll shifter is installed in a place giving facility to the maintenance, and is not engaged with a housing 1; then, the roll shifter is engaged with a roll chock through a rod, joint, pin of joint mechanisms 23, 29, 30 freely followable to vertical and lateral movements of the roll chock, and besides, through a universal joint attached to the roll chock so as to align the roll chock with the axis of a roll to be shifted. Hereby, a stable shifting force is applied to the roll chock. Besides, in order to easily and quickly practice the roll replacement work, a cylinder 25 is installed for vertically shifting a rod to detach a universal joint; and a holder 27 is installed for holding a rod 23 and a slide hearing 24 for reducing the resistance to movement of the rod 23. By the present constitution, each device is independently set up so that the whole construction is made simple and the facility of maintenance is greatly improved.
