Surface Inspection: A non-marking roller table installed at the exit side of the Turret Head™ Slitter allows efficient physical and visual inspection of the strip surface after slitting. The Inspection Table also serves as a scrap side-trim deflector when it is in the running position, and serves as a slitter tooling inspection platform when the Table is withdrawn from the line during head changes.
Tensioning Surface-Critical Materials: In order to generate tightly wound straight side-wall coils, the Lomanco Slitting Line is equipped with two tensioning devices: a Pneumatic Pad Tensioner, and a non-marking Roll Tensioner. The Pad Tensioner employs felt faced pads engaged by pneumatic cylinders to generate winding tension for non-critical surface materials. The Roll Tensioner employs special large diameter high-traction non-marking tension rolls to generate winding tension for pre-painted steel and aluminum coils. A high-capacity water cooled pneumatic brake provides remotely adjustable strip tension. The strip tensioning devices can be engaged independently or in tandem, depending upon the materials being processed.

Exit End: A exit pass line/tach roll, Overarm Separator, Strip Threading Funnel, and a coil splitting Guillotine Shear are located at the exit end of the Slitting Line. The pass line/tach roll directs the strip to the Recoiler and senses the strip speed and linear footage. Because of the high pass line arrangement, the strip rides above the pass line roll and not under, eliminating the possibility of surface scuffing or marking. A guillotine Shear efficiently "splits" coil ODs. The Overarm Separator is attached to the Exit Unit and is supported from both ends making it extremely rigid to assure squareness with the Recoiler. The quick-change Overarm arbor swings-out for 2-minute tooling exchanges. A hydraulic cylinder positioned table working in concert with the Overarm mounted deflector forms a funnel to direct slit strips into the Recoiler drum.
