Decoiler: Reels-Single and Dual spindle:
The coil reels used in most uncoiling and recoiling applications, primarily because they inherently avoid stock deformation problems. The stock is supported on the center core of the coil and is unreeled as required. May be fitted with a variety of drive and braking systems, combined with coil cars, pinch rolls, power straighteners, overarms, rolling mills or configured as stand alone systems. Reels are the best choice for thin, prefinished and other mark sensitive materials.
- Coil reel is suited to uncoiling a wide ranges of material
- Coil reel is easily able to maintain programmed tension downstream. Can be drag braked or powered unit
- Coil reel can be adapted to uncoil or recoil. Can easily rewind unused material
- Coil reel is less costly than cradles
Easy, fast loading of coils is the single most important benefit offered by cradle-type decoilers. They are often used in combination with straighteners for faster loading and adjustment, low power requirements and maintenance. Cradle-straighteners also save plant floor space.

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
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.
Mecon feeders use precision Servo motors and controls, precision drive systems and heavy duty components to provide quick accurate indexing of material. They are designed to pull from an accumulation loop (not directly off the coil), and accurately position the material each cycle.
Fast, Flexible Operation. RThe controls are located on a console or pedestal for convenient entry of job settings. Setup time is reduced to seconds, just enter the values using the keypad. Roll positioning accuracy of +/_ 0.002” can be achieved with the sevro driven roll feeds. The drives provide precision control of position, speed, acceleration and deceleration.
- Diagnostic display of operating status and faults
- Feed before press or press before feed modes.
- Upper feed roll is driven is driven using a constant mesh 4 gear train, gears are hardened 4140 steel
- Hardened vertical side guide rolls align the strip to the tooling
- Entry ramp rolls support material to ensure smooth flow from loop to feeder
Accurate Part-to-Part Advancement
Roll position accuracy of .001 (inch) can be achieved with Mecon electronic roll feeds. Servo drives provide gradual, and controlled, acceleration and deceleration. Stock payout is smooth and rolls do not slip.

Side Shifting Feeders
Mecon offers roll feeds with a servo driven shift base to allow optimum use of material.
The standard control has 3 pre-prograrnmed patterns. Shift and Feed distance are simply keyed in at the operator’s console. Select the pattern, press start and the machine is ready to run. Custom programs available.

Feeder Straightener CombinationsThese 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 decoiler.
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.
Reduced downtime for coil changeovers may make the difference between profit and loss. Fast loading, easy “hands-off” operation makes for a streamlined, safe and profitable operation. …see more
