THIS MAIN SHAFT HAS A 12" DIAMETER. MANDREL (DRUM): AN EXPANDING MANDREL GRIPS THE INSIDE DIAMETER OF THE COIL. THE MANDREL IS COMPRISED OF STEEL SEGMENTS 2" THICK WHICH PREVENT DISTORTION AND PROVIDES LONGER LIFE. EXPANSION AND CONTRACTION OF STEEL WEDGES POWERED FROM A ROTATING HYDRAULIC CYLINDER.

THIS SHAFT IS PART OF THE MAIN GEAR TRAIN DRIVEN BY THE HYDRAULIC MOTOR. GEAR RATIO TO THE MAIN SHAFT IS 2.33:1. CENTERING ADJUSTMENT: THE UNCOILER HOUSING IS SUPPORTED ON HARDENED WEAR PLATES ON THE MACHINED WAYS OF A FABRICATED STEEL SUB-BASE. A HYDRAULIC CYLINDER MOUNTED IN THE SUB-BASE SHIFTS THE UNCOILER EITHER SIDE OF CENTERLINE AS REQUIRED FOR COIL ALIGNMENT. HOLDDOWN ROLL ASSEMBLY: THE HOLDDOWN ROLL IS A STEEL ROLL WITH A RUBBER COVERING. THE HOLDDOWN ASSEMBLY IS POSITIONED ON THE ENTRY SIDE OF THE UNCOILER AND IS USED TO HOLD DOWN THE OUTER WRAPS OF THE COIL. THE HOLDDOWN PRESSURE IS OBTAINED BY HYDRAULIC CYLINDER. HOLDDOWN ROLL IS DRIVEN BY A HYDRAULIC MOTOR. UNIQUE NEW FEATURE: BOTH SIDES OF THE MAIN HOUSING ARE PRE-MACHINED TO ACCEPT THE HOLDDOWN ROLL.
