ABSTRACT:
The mill stand houses a pair of upper backup rolls and a pair of lower backup rolls between which pairs the upper and lower roll drive shafts are journalled. The overhung work rolls are affixed to the ends of the drive shafts. Apparatus is provided for automatically adjusting the work rolls longitudinally, for automatically adjusting the loading on the backup rolls and for maintaining the drive shafts parallel under load. An automatic gauge control system for making the above adjustments and capable of varying the mill stand modulus or spring continuously from a stiff or constant roll gap modulus to a soft or constant pressure modulus is also described.
