Abstract
An adjustment device and method to guide a metal product along a determinate nominal rolling axis. The device comprises a central body disposed astride the rolling axis, two guide units mounted movable on the central body, opposite each other with respect to the rolling axis and each provided with at least a guide roller for the metal product, and an adjustment mechanism mounted on the central body and operatively connected to both the guide units, in order to actuate the selective movement thereof with respect to the central body at least in an approach toward the rolling axis. The adjustment mechanism comprises a system of pantograph levers having two levers pivoted to each other and to the central body in correspondence to the rolling axis by means of a pin, and first constraint means disposed on each lever on opposite sides to the pin, so as to connect each lever to both the guide units.

24. An adjustment method to guide a metal product along a determinate nominal rolling axis, using a device comprising a central body disposed astride the rolling axis, at least two guide units mounted movable on said central body, opposite each other with respect to the rolling axis and each provided with at least a guide roller for the metal product, and an adjustment mechanism mounted on said central body and operatively connected to both said guide units, the method comprising at least an adjustment step in which the selective movement of said guide units is actuated with respect to said central body at least in an approach to the rolling axis, by means of a system of pantograph levers of said adjustment mechanism, having at least two levers pivoted to each other and to said central body in correspondence with the rolling axis by means of a pin, and first constraint means disposed on each lever on opposite sides to said pin, so as to connect each lever to both said guide units.
