Available in various models with fixed speed / A. C. variable speed & having loop control system to synchronize with Press-Feeding Speed along with control panel.

The decoiler & straightener heads are selected from our standard range to offer modularity & fast deliveries still maintain the quality levels of individual equipments.

We are engrossed in providing a premium quality Bevel Gear Type Decoiler Machine. De-Coiler offered by us finds application as accessory machine that is used as support for expanded metal mesh machine. The offered system finds application in opening rolling sheet irons that is then fed into expanded metal mesh machine. Here, our expertise lies in supplying the un coiler in different options including in form of heavy duty un coiler, stocker reel, double stock reel un coiler and others that allows customers to choose the model as per their coil diameter as well as coil weight handling requirements. Here, we can also customize these de coilers based on the technical parameters provided by customers concerning maximum loading weight, inner diameter of coil, width of coil need to be de coiled.

• Automatic Speed Control
• Simple and Ergonomic Coil Insertion
• Integrated Light Curtain Safety System
• Durable Felt Tension Pad

Blue Industrial Decoiler Machine has a spindle and coil that hold heads & housed in mechanical, ground housing and rotates on sealed dustproof bearing (element). The decoiler having convenient loop control unit to maintain loop made by a coil with the assistance of antenna type loop sensors, limit arm through limit switches or photo sensors.

• 15/ 17/ 19/ 21 straightening rolls
• Straightening roll diameter from 10 mm to 200 mm to cover a wide range of jobs
• Straightening accuracy /- 0.01 to 0.07 is achieved depending on input component conditions

The decoiling machine is mainly used to decoil various metal coils, and work together with other machines to make a production line.

MTC series steel coil decoiling machine with coil loading car is suitable for: steel coil 75-3200 mm width, thickness is 0.15-25 mm, maximum weight of 45 tons!

Our Hydraulic series uncoil is for press feed line, cut to length line, slitting line and tube mill.

The coil is handling and collapsed and expansion by hydraulic expansion. Steel fabricated duly machined, mounted on heavy duty shafts on anti-friction bearings. It is collapsed by Hydraulic cylinders. The individual body is fabricated steel construction.  Mandrel equipped with hydraulic actuated 4 segments sliding wedge for expansion.

Pneumatic controlled braking system is provided to minimize over running of the coil with tension. A brake is provided to stop the line whenever the line stops for any reason.

2 In 1 Compact Decoiler / Straightener, Steel Coil Feed Line -2 In 1 Decoiler Strip Straightener Machine, Sheet Metal Steel Roll Leveling Machine Uncoiler

Two-in-one uncoiler and straightener, which is combine with steel coil uncoiler (unwinding) and the straightener (leveling). Compared to three independent machines on the same production line, the floor space is more shorten and the overall structure is more compact. The complete feeding line are included the NC servo roll feeder and stamping press as well, but the length of coil loop should be reserved between the straightener and the feeder. If your plant has enough space, we will recommend you 2 in 1 model combined with the feeder, the overall budget is lower than the 3 in 1 model
