As shown in FIG. 1, a lower web guide pair 3A divided into two parts is fixed to L-shaped support stands 4 and 4', respectively.
' is a moving platform 8,8 guided by a guide shaft 7 whose both ends are fixed by bearings 6,6' fixed on the elevating frame 5.
It is placed and fixed on the top of '. Further, one ends of screw jacks 9, 9' are rotatably fixed to the supports 4, 4', respectively, and these screw jacks 9, 9' are connected to the opening/closing hydraulic motor 10.
, 10', they can be freely moved toward and away from each other in the direction of arrow L. Moreover, the elevating frame 5 includes an elevating hydraulic motor 11 and a connecting shaft 12.
It is supported by screw jacks 13 and 13' which are movable up and down in synchronization with the direction of arrow H. The lifting hydraulic motor 11 and screw jacks 13, 13' are fixed to a mill housing (not shown).
