The Material

It helps to understand the nature of the input material and how it got that way. Most strip or coiled material begins its final processing phase as a slab. The slab was reduced to the final gauge by rolling, then wound into a large coil. It has grown greatly in length and nominally in width. High internal stresses in the material are often created during the rolling process.

The internal stresses often vary from the outer wraps to the inner wraps and from the center to the edges. The strip is unwound, slit to width and rewound. Center slit material often yields the best material, edge cuts often yield the worst. When the internal stresses are not balanced, the slit material will have camber. The greater the stress imbalance, the worse the camber. In some instances, additional processing will be necessary to balance the internal stresses and eliminate camber. Poor material is a leading cause of difficulty in tracking the strip through the entire system. Camber problems will consume your profits!

To avoid many coil-handling problems, insist on quality material, reject that which does not meet your standards, and use the proper uncoiling system.


Selecting the proper options for your system will provide big paybacks in productivity gains.

  • Eliminate waiting time for overhead cranes or lift trucks by installing coil cars and coil storage ramps Coils can be staged when convenient and are ready when the system needs them
  • Reduce handling time and increase safety with coil clamping arms and threading equipment
  • Use dual spindle uncoilers when feeding high demand systems like rolling mills or systems using partial coils
  • Use sonar loop controls to smooth the uncoiling – straightening process, maintain proper loop geometry, and deliver more consistent material to the feeder
  • Use a side shift base on the uncoiler to allow easy coil alignment and adapting for camber during processing
  • Purchase the best material possible to ensure good quality, consistent parts

Mecon Industries Limited manufactures a variety of coil processing systems.
Many factors should be considered when determining the optimum arrangement.

• Plant space available
• Crane capacity
• Lift truck capacity
• Mark sensitivity
• Material thickness
• Material width
• Material strength
• Coil handling: – load and unload partial coils, or run full coils to end
• Coil weight
• Coil inside diameter
• Coil outside diameter
• Production required: -feed length, speed, feed angle, feed time
• Process type: – progressive stamping, blanking, blank and transfer, cut to length, pre-punch, etc.
• Budget

Mecon Industries Ltd Uncoiler systems


















Most systems require an accumulation loop. The accumulation loop is used to allow the uncoiling process to payout at a nearly continuous rate while the feeding equipment stops and starts. Ideally the loop will accumulate at least 2 feed lengths of material. Thickness, material yield strength, and feed length are important factors to consider when determining loop geometry. The loop must store sufficient material to allow smooth operation. The material must not be curved smaller than the minimum bend radius to ensure that the proper loop shape is maintained and kinking does not occur:

• The loop length should be 1000 to 1400 times the material thickness.
• Ramp rolls should support the material as it enters and exits the loop.

A pit is recommended if the required LOOP HEIGHT, is greater than the process height

The Uncoiling Problem

The strip is slit to width. When internal stresses are not balanced, the slit material will have camber. The greater the stress imbalance, the worse the camber. Camber is a leading cause of difficulty in tracking the strip through the entire system. To avoid many of the problems of coil handling, insist on quality material, reject that which does not meet your standards, and use the proper uncoiling system.

The Two Basic Systems

The two basic systems, coil reel and coil cradle, have both advantages and disadvantages. In general reels work well with thin material and cradles work well with thick material.

Electronic Roll Feeding

With the continued push toward even smaller batch runs, die changes and set up time have become more critical. Flexibility of the major components (press, feed, straightener, uncoiler, coil cradle) is an important factor. The time saved in set up and the flexibility of Electronic Roll Feeds (ERF) are helping manufacturers increase productivity.

Ease of set up is a key feature. ERF’s take less time to set up than mechanical feeds and trial and error adjustment: at the control panel, just enter feed length, speed, and press “start.” Mecon will size the drive and set the acceleration and deceleration to best match the production requirements.

When possible, lower accelerations and speeds are used. This gives increased accuracy, smoother material flow, and eases the load on the uncoiling system. Another outstanding advantage of the ERF units is their ability to easily adapt to the press feed angle.

Both types of uncoiler have advantages and limitations. In general, the reel works well with thin to thick material, the cradle works well with thicker materials.

Consider the Reel if:

  • Material is sometimes thinner than 0.080″
  • Rewinding full or partial coils
  • Precise tension control is necessary
  • Material marking is critical
  • Straightener is pulling the material off the coil
  • Powered uncoiling of materials thinner than 0.150″
Consider the Cradle if:

  • Material is always thicker than 0.080″
  • Rewinding is not important
  • Tension control is not important
  • Material marking is not critical
  • Powered uncoiling of materials thicker than 0.150″

NEW Rules New Tools: Powered Straighteners

The new HSLA materials being used in the industry are posing new challenges for coil handling. Straighteners must be sized on the basis of the type of material to be processed, the thickness range, the stock width, and Yield Strength. Straighteners are generally positioned close to a non-motorized reel to pull material directly off the coil. The primary function of straighteners is to remove coil set and cross bow, and to pay out material to the accumulation loop as required for the feeder. For most materials and flatness requirements, use straighteners with five to seven rolls. For some materials, and to meet high flatness requirements, more rolls may be necessary.

Mecon straighteners are:

  • Easy to thread, with variable speed drives.
  • Able to match process demand automatically.
  • Heavy duty construction.
  • Easy to set, with soft starts and stops.
  • All lubrication points marked and easily accessible.
  • Capacities in mild steel from 0.010” to 0.450”, 12”-72” wide (heavier on request)
  • Standard payout speed of 0-80 fpm.
  • Digital indicators show straightener roll position.
  • Entry side guide rolls.
  • Entry and exit support rollers.
  • Optimized for HSLA materials

Straightener Capacity

Note: Several factors affect straightener processing capabilities therefore machine capacity calculations are to be used as guidelines only. Consult Mecon engineering with specific application requirements.

Feeder Straightener Combinations

These double operation units have become more accurate and faster as high performance motors have become available. Accuracy is now comparable to stand alone feeders. They are designed to straighten and feed material from a powered uncoiler.

The material is being processed closer to the press with the coil being fed directly into tooling. The positioning of the material is accurate and coil set is eliminated.

Feeding of a new coil stock through the straightener is accomplished without opening the straightener head or disturbing the depth settings. Straightener-feeder combinations save space.

Proposed Solution: Coil car, Uncoiler, Power Straightener, accumulation loop, Feeder.

a) Coil car model 500cc with power top rolls:

  • A coil car with power lift of 20″ and power travel.
  • The car will travel on tracks to transfer the coil from the park position to the uncoiler, or from the uncoiler back for storage. The coil rests on non-powered rollers.
  • The rolls are used to aid in threading thicker materials into the straightener. Traverse, and lift functions are controlled manually from a central control station.

b) Uncoiler model 500btj72. ( capacity 50,000 lbs x 72” with spindle end support)

  • The uncoiler has an air brake to maintain coil tension during processing.
  • A hydraulic motor, and clutch for jogging coil. Jog speed 4 rpm.
  • Upgrade to heavy duty back tension brake with coil diameter sensor to maintain constant tension during unwind of coil.
  • The mandrel is 4 segments, with wedge style expansion and is hydraulically expanded/retracted.
  • Inside diameter range of 19.5 to 24″.

c) Coil over arm with power wheel: Peeler / coil breaker.

  • The over arm clamps onto the coil to contain the coil end when the straps are cut.
  • The wheel is powered by a hydraulic motor and drives the coil to thread the start of the coil to the input pinch rolls of the straightener.
  • The Peeler extends to contact the coil and guide the start of the coil.
  • The coil breaker lifts to press the strip against a flattenning block on over arm and thus de-kink the start of the strip. This allows easy threading of steel into straightener.

d) Straightener model 5str72-bu: Series straighteners have:

  • 11 hardened and ground rolls running on precision needle bearings, bearings lubricated from centralized manifolds (hand lubricated)
  • Entrance and exit pinch rolls; air actuated, lower rolls driven.
  • 2 entrance pinch rolls, 5.000″ diameter, close onto material to drive starting edge thru straightener, not required to change straightener settings for threading.
  • 2 exit pinch rolls, 5.000″ diameter, open for threading, close for running.
  • 7 straightenning rolls, 5.000″ diameter, 4 lower rolls all driven, 3 upper rolls idle.
  • Upper rolls motorized individual adjustment, position shown on .001″ graduation counters.
  • Straightener drive: Variable Frequency AC Motor control with AC induction motor, and brake.
    speed 0-80 fpm. infinitely variable.  These drive systems give very smooth acceleration and deceleration with no sudden shocks to the material or drive components, and thus extend machine life and limit material marking.
  • In automatic mode a sonar unit senses the height of the material in the loop between the straightener and the feeder.
  • The sensor signals the drive to speed up or slow down to maintain the loop automatically.
  • The uncoiler brake is provides back tension to limit coil overrun and to help prevent coil slack.
  • n manual mode the speed is set at a low speed and forward or reverse movements are selected by pendant mounted switches.
  • HD Support rolls: The drive system will be increased to 40 hp to match the higher capacity of the straightener. Each straightener roll is supported by rolls to limit roll deflection when processing heavy materials. Lower support roll positions are fixed and not adjustable. Upper support rolls travel with the straightener roll during adjustment.
  • Material guidance: Coil peeler and breaker guide material into straightener.
  • Entrance vertical guide rolls to track the material.
  • Exit ramp rolls support strip as it exits straightener and drops into loop.

h) Estop and Gate monitor circuits .

e) End pivot threading table. EP72x168:  End pivot threading table attaches to the straightener.

  • Hydraulic cylinders actuate the table. The table lifts to support material between the straightener and the feeder as the beginning of the strip is being jogged to the feeder.
  • Table length is dependent on the loop geometry, which is related to the maximum material thickness, material strength and feed length.

f) Straightener control station and integration: 

  • Contains the controls for the coilcar, uncoiler, overarm/peeler/breaker station, the straightener, and the threading table.

g) Feeder model 600f72-IHD: The feeder is a floor mounted machine with a press adapter bracket, a seperate control console and a remote jog pendant. The press adapter bracket rigidly attaches the feeder to the press. The jog pendant allows the operator to walk with the material when threading.

  • Feed Rolls: The rolls are 73.5″ face width x 6.000″ diameter. They are hardenned, precision ground and 100rms chrome surfaced for excellent grip and wear resistance.
  • Upper and lower rolls are both driven.
  • Passline Adjustment; Passline height is adjusted by a powered elevator, total adjustment 12″.
  • Pilot release: The feed rolls are pnuematically lifted and lowered. The pilot release circuit is signalled by a press cam to lift the rolls and lower the rolls to release the material.
  • Anti-Backup brake mounted on the motor is standard. The brake is spring engaged and is on anytime the power is off the servo motor. When the pinch rolls are contacting the strip, the brake will not allow the material to slip back into the loop.
  • Servo-Drive: An Indramat high performance brushless AC servosystem drives the feed rolls. It is conservatively rated and is capable of peak torques well in excess of the rated torque.
  • The servo motor is mounted to a servo quality “zero” backlash gearbox, and mounted under the feed rolls. A high performance Gates Polychian drive connects the gearbox output shaft to the lower feed roll. Components Mkd Motor, Alpha Sp gearbox.
  • Computer Control: An Indramat motion control – Mecon OCS control runs the servodrive. It is very flexible. Program parameters, speed and feed length, etc. are input directly through keypad. Displays operating mode, error and system diagnostics, etc.
  • Very fast setup of next job.
  • Die and press protection through monitoring of press feed signal and feed completion.
  • High Performance: The performance is tuned to suit the specific requirements. Feed length accuracy better than +/- .003″

Typical 600f72 set up
a=240 in/s/s,, feed angle = 180 degrees, maximum uncoiler speed = 80 fpm
20 spm —- 45″ progression
30 spm —- 28″ progression
40 spm —- 20″ progression

h) Safety circuits. The control is wired with dual path Emergency Stop and Gate Monitor circuits. The control relays are Safety rated contactors with external reset.

  • On Emergency stop, all high voltage power is disconnected from drives and hydraulic power unit, and 120vac and 24vdc power is disconnected from all solenoid valves, control power remains connected.
  • On Gate monitor circuit open, the system will allow manual functions, but will prevent automatic functions.
