Rollers 2 through their rotation axes 3 are mounted in cases 4. Cases 4 are connected with rods 5 of power cylinders 6 arranged in bed 1. Power cylinders 6 are used as drives of synchronous movement of rollers 2 with cases 4 to the centering axis and therefrom. Each of the cases is equipped with a pair of torsion springs 7 in the inversed manner installed on axes of their rotation, herewith one end of each spring rests on the case, the other end – on the bed.
