Dual Rotor Helical Scrap Chopper: Scrap edge trim is automatically directed into a Dual Rotor Scrap Chopper. Independent inboard and outboard heads are equipped with upper and lower rotors fitted with helical cutters. Upper and lower rotors are geared with zero-backlash gearing for perfect rotational synchronization. A 200 HP DC motor synchronized with the slitter speed drives inboard and outboard Chopper heads. Chopped scrap is collected and discharged into a scrap bucket via hinged steel belt conveyor.

Strip Tensioning: A hydraulic Threading Table carries the slit strips over the looping pit, through a set of strip separators, and into a Hydraulic Strip Tension Stand. The two-sets of quick-change strip separator arbors are positioned for off-line set-up and running by hydraulic cylinders. The slit strips are supported on a large pass line roll at the exit side of the Tension Stand and fed into a Hydraulic Threading Funnel that directs the strips into the Recoiler drum gripper bar. A hydraulic Overarm Separator with hydraulic tail hold-downs guide the strips onto the Recoiler.

Recoiling: The slit strips are rewound on a massive Recoiler drum with 2" thick heat-treated forged steel expanding segments and a solid 3" diameter hydraulic gripper bar. A floor mounted Outboard Support engages the free end of the Recoiler drum to eliminate deflection while winding 90,000# coils. A huge multiple ratio parallel shaft helical gear reducer and DC motor generates over 1.1 million inch pounds of torque to rewind the high-strength heavy-gauge material. After the slit coils are securely banded, they are unloaded from the Recoiler by Coil Car and transferred to a 4-Arm Coil Storage Turnstile.
