COMBINATION QUICK REMOVAL AND ADJUSTABLE WIDTH WORK PRESSURE BACK-UP ROLL OR BILLET ROLL A combination quick removal and segmentally adjustable work pressure back-up roll or billet roll (commonly called a billy roll) is mounted to freely float in a vertical direction with one end mounted within a sectional clamp. The clamp sections may pivot to open for quick removal of the entire roll. The roll is constructed of sleeve segments having their end faces of tongue and groove constructions which interfit to form a continuous roll and which may be longitudinally adjusted with respect to each other to accommodate work pieces of different widths and to facilitate removal and replacement of sections that may be worn more than others, without having to replace the entire roll.
