A two-line roll stand comprising:a frame; an upper shaft on the frame; two lower shafts on the frame spaced horizontally from each other below the upper shaft and centered on axes forming with an axis of the upper shaft an isosceles triangle; at least four identical drive units each having a pair of rolls, the lower shafts each carrying one of the drive units and the upper shaft carrying two of the drive units, the lower-shaft drive units being tipped outward away from each other with the respective rollers defining a pair of roll lines spaced below and symmetrically flanking the upper shaft and the upper-shaft drive units being tipped downward with the rollers of each upper-shaft drive unit being aligned on the lines with the rolls of the respective lower-shaft drive units; and drive means for synchronously rotating all the shafts and thereby rotating all the rolls via the respective drive units.
