Abstract
The present invention is to provide a compact roll stand apparatus, particularly of four-roll type, comprising both a roll parting adjustment device and an all-roll drive device. Further in detail, a roll stand apparatus comprising: a plurality of grooved rolls arranged radially, with substantially same degree intervals, from the pass line along which material bars and rods are driven, and whose rotational axes lie on a plane; eccentric shafts each rotatably supporting each of said grooved rolls; a device for simultaneously rotating said eccentric shafts and also simultaneously adjusting radial distances from said pass line to the rotation axes of said grooved rolls; driven gears each mounted concentric with the rotation shaft of each of said grooved rolls so as to rotate integrally with each of said grooved rolls; driving gears whose rotation axes lie on a plane apart, in the direction of said pass line, from said plane where the axes of said grooved rolls lie, and which engage with said driven gears; and a drive device for simultaneously rotating said driving gears.
