Abstract: A machine particularly useful for continuously descaling wire and finishing tubular products. The basic machine incorporates a heavy, circular planetary mounting plate having a pair of independently driven finishing brush wheels, mounted thereon which rotate in enagement with the wire being finished and at the same time are rotated in an orbit about the wire by rotation of the planetary mounting plate. The planetary mounting plate is belt driven from an electric motor. The pair of finishing brushes are belt driven from a second electric motor and are provided with an additional outboard mount so that relatively longer wheels may be used. The brushes may be syncronously adjusted with respect to the workpiece without interrupting operation of the machine. Adjustable wire guide and support means are disposed adjacent the bight of the wheels to properly position the workpiece while it is being engaged by the finishing wheels.

Abstract: 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.

Abstract: An abrasive belt tension and oscillating assembly for use with wide belts resulting in the use of long and heavy rolls and mounting frames requiring heavy duty supports for the ends of the pivotally mounted tension roll and further requiring stabilizers in the form of dual guide pins with rack and gear construction for uniform movement of the idle or tension roll assembly and uniform tension on the belt regardless of the width and position of the belt.
