Scrap Disposal: The ThyssenKrupp Slitter employs a pair of pushbutton unloading Scrap Winders. Scrap Winders are extremely reliable and require little maintenance. Scrap bundles discharged from the Winders are deposited onto a hinged steel belt conveyor that carries the bundles to a large scrap container.

Surface-Critical Strip Tensioning: The ThyssenKrupp line employs two tensioning devices that develop strip tension necessary to produce tight straight-walled light gauge slit coils. A Pad Tensioner is employed for tensioning non-critical coil and the non-marking Roll Tensioner is employed for processing surface-critical coil. Quick-change entry strip separators guide the slit strips from the looping pit into the Tensioner. The Pad Tensioner is equipped with quick-change friction pads that can be exchanged with fresh pads in one-minute. The Roll Tensioner employs non-marking tension rolls with special roll covers to generate strip tension without surface marking. The tension rolls are equipped with variable tension control and a jog drive for strip threading.
Tension Pad and Non-Marking Tension Rolls can be employed in tandem or engaged independently.
Exit End Equipment: The Overarm Separator is rigidly mounted onto the Exit Unit frame to eliminate frame deflection and resulting misalignment that can cause coil side-wall scuffing and coil oscillation. A heat-treated swing-out tooling arbor allows Overarm tooling to be exchanged in 2-minutes. A "side-adjust" feature allows Overarm alignment to be adjusted while running. An Exit Shear is used to "split" coil ODs and square tail ends. A Feed Table that acts in concert with an Overarm mounted deflector plate forms a funnel to guide slit strips from the Exit Pass Line Roll to the Recoiler gripper bar. A Paper Interleaver can feed pre-cut paper into the rewinding slit coils.
