Compact two-line rod-rolling stand

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;
• respective drive gears on the shafts;
• a plurality of identical drive units each having a pair of rolls and gearing connected to the respective rolls, the lower shafts carrying at least two of the drive units and the upper shaft carrying at least four of the drive units;
• respective bevel gears on the shafts connected to the gearing of the drive units, the drive units of one of the lower shafts being tipped outward away from the drive units of the other lower shaft with the rollers of the lower-shaft drive units defining a pair of roll lines spaced below and symmetrically flanking the upper shaft, 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 including a single motor having an output directly connected to the drive gears for synchronously rotating all the shafts and thereby rotating all the rolls via the respective bevel gears and the gearing of the respective drive units.
