Edge wave and center-buckle strip defect correction is accomplished via automatic computer command or operator override. A computer memory commits the back-up and work roll positions to a memory for future recall. This feature is a valuable time saver particularly when processing partial coil runs. Leveler calibration is a time-consuming job with old screw jack and wedge Levelers. The Hydraulic Leveler includes an "Automatic Calibrate" feature that calibrates the Leveler in a few minutes without dismantling Leveler components.

Precision Electronic Servo-Feed: A high-traction non-marking Servo-Feed driven by a precision microprocessor AC servo feeds and meters the surface-critical strip to ±0.005" length tolerances. The Servo-Feed draws the leveled strip from the free-loop and feeds the strip to a pre-set length through the Shear. Part lengths are precisely measured by an electronic encoder, while a microprocessor automatically establishes ideal acceleration/deceleration rates. Sheet length and batch count are quickly entered into the digital operating system. Servo Feeds compare favorably to "reciprocating mechanical feeders" in productivity and reliability. A reciprocating mechanical feeder grabs the strip, shoves forward to an adjustable positive stop, engages holding clamps, shoves the reciprocating clamp backwards, grabs again, and releases the holding clamp before starting another feed cycle. Grabbing, releasing, sliding backwards, and re-grabbing consumes the majority of a reciprocating feeder cycle time. By comparison a Servo-Feed simply rotates feed rolls in one direction. The need to make multiple reciprocating feed cycles further diminishes a reciprocating mechanical feeder's productivity when producing long sheets. The Servo-Feed's non-reciprocating operation, low acceleration/deceleration rate, few moving parts, and a total absence of chains, length adjust screws, shock absorbers, limit switches, valves, pumps, slides, clamps, & hydraulic hoses gives it consistent accuracy and "bullet-proof" reliability.

Hi-Speed Hydraulic Shear: The ATAS CTL Line employs a heavy-duty hydraulic cylinder powered Shear to cut sheets to length. The Hi-Speed Hydraulic Shear is capable of a 60-strokes/minute cyclic rate, comparable to a mechanical shear cyclic rate. The Shear employs PLC controlled hydraulic cylinders to power the upper guillotine ram through its cycle. 4-edge shear blades are mounted on the guillotine ram and the lower blade holder. Blade gap is adjustable from a single point for processing the entire gauge range. The ATAS Shear is quick, has a virtually silent shear cycle, and offers "bullet-proof" reliability.

Reject Belt & "Flipper" Sheet Stacker: Cut sheets are carried away from the Shear on a variable-speed Belt Conveyor. The Belt Conveyor has the ability to direct cut sheets to a scrap cart to discard scrap head & tail ends or into the Sheet Stacker. The Sheet Stacker carries cut sheets on a set of non-marking roller "flippers" until the sheet is directly above the stack where it is released. The flippers are pivoted open and closed by air cylinders. An Elevating Stack Table is automatically elevated to just below the sheet release elevation to minimize the sheet drop distance. An air float system generates an air film that helps support light gauge sheets during the stacking sequence. Pushbutton adjustable side skirts and end stop contain the sheet stacks and produce solid-block sheet packages.

Panel flat sheets, precise tolerance, solid-block sheet packs, productivity, and bullet-proof reliability made the choice of a Braner/Loopco Cut-to-Length Line a "no-brainer."
