Abstract
A rolling roll with rolling ring which includes a pair of supporting half-shafts, which cooperate with each other and are suitable for the keying of the relative rolling ring. The keying is carried out substantially at the zone of cooperation between the half-shafts, the half-shafts (12a-12b) being set in traction against each other by means of a tie rod. The cooperation between the two half-shafts is obtained with a tapered coupling of a male/female type of the half-shafts to each other, this male/female coupling providing a zone of superimposing of terminal portions (12a-12b) of the half-shafts (12a-12b), this zone covering at least an important part of the axial extent of the rolling ring.
