Product Description

Compact 3 in 1 Press Feeding Line Uncoiler Straightener Feeder Stamping automated production line

Coil Feeding Line consist of Decoiler Straightener NC Servo Roll Feed for Coil Feeding Line are therefore able to work thickness from 0.6 mm to 6.0mm with width that range from 70 to 1800mm and weight up to 20tons depending on the needs of the specific customer.Various kinds of materials can be machined, from soft ones such as aluminium and alloys, to hot and cold-rolled materials and carbon and stainless steel, and to high-strength materials and lamination steel.

Decoiler Leveler Feeder , with Decoiler, straightener and feeder machine in one combination unit. It used to uncoiling metal strip from coil stock, straightening it to required flatness and feed it to press machine for stamping process.Thanks to a well-knit body and advanced mechanical structure, it can easily handle coil stock up to 20tons.

With YASKAWA servo motor and drive and MITSUBISHI PLC, the feeding line can achieve the very accurate feeding ±0.15mm. Moreover, the whole compact feeding system is only 4.5m length, which will save a lot of workspace for your press workshop.

Features of each parts of Metal sheet coil feeding line

1. Automatic loading coil car

Automatically lift the coil to the mandrel of the Decoiler Machine with loading coil car. And then the mandrel can expand and clamp the coil.
a) Loading capacity 5T-20T
b) Up-and-down movement the coil car by hydraulic cylinder
c) Horizontal movement by hydraulic motor
d) 2 Coil well-knit, no disperse

2. Decoiler:

b) Max. loading capacity: 5ton-20ton
c) Expansion type: Hydraulic
d) Brake type: pneumatic, stable and safe, also can prolong lifetime of the power system
e) Mandrel hydraulic expansion system. The hydraulic station provide power to drive the hydraulic cylinder to expand & draw back the mandrel to clamp coil or release the coil.
f) Press arm device to hold the strips, preventing coil loose. Further more, the press arm equipped with a PU roller to hold the strips, don`t scratching strip surface.
g) Support arm device. Driven by hydraulic-cylinder, it was use to guide and support strips, Further more, several sets of rollers installed in the device, and all rollers were chrome plated, the surface is very smooth, preventing scratching material surface.
h) Limit arm device, clamping coil in width direction, preventing coil collapsing when coil were too narrow. Further more, the width between two back gauge arms were designed adjustable by operate the manual wheels, coil width range is 70mm-1800mm.
i) Machine equipped with hydraulic station, providing oil pressure to drive the mandrel expansion & contraction and hydraulic cylinder.
j) Sensor device: electric eye loop control system, stable, safe and long lifetime. With the electric eye loop control system, the decoiler release strips automatically.(you can refer to the following image)

3. Straightener-Feeder

a) Structure: Servo motor driven, synchronous belt transmission, gear transmission
b) Servo motor and driver: Yaskawa, Japan
c) Straightening roller: 9 (upper 5/down 4)
d) straightening roller diameter:φ88mm
e) Pinch roller: 2pcs
f) Feeding roller: 2pcs

All the roller material is GCr15, after quenched, high frequency annealing, the hardness is HRC58°-60°and then precision polishing.
g) Gear: Material adopted 40Cr. The center quenched, teeth high frequency annealing and precision polishing.
h) Straightening adjustment: eccentric turbine worm adjustment, dial indicator display; Electric adjustment can be provided also
i) The entrance clamping roller: 2pcs
j) Release type: pneumatic
k) Feeding control: get signal from press encode or cam box, and controlled by PLC and display on HMI.
l) Material input guide roller: 1 group (manual adjustment)
m) Coil Inlet device. It equipped with chrome-plated rollers and guided strips to go through the straightening part.
n) Straightening device. It was mainly to press and flat coil head and end of the coil. Usually, the coil head is curvy, if without this device, the material is hard to go through the straightening part. But with this device, when the strips comes then entrance of the straightening part, the tip flatness device and press and flat the coil head and go through straightening device smoothly.
o) Handwheel: The operator crank the manual handle to adjust the accuracy of the straightening part.
p) Outlet bracket: assistant support material device. It was mainly used to guide strips from straightening part to press machine.
q) Control box. It was mainly used when coil run out and need to change a new coil and let the strips go though the straightening part at manual model.
r) HMI. The operator operate the machine and set data in this device.
s) Worm gear screw jacks device. It main used to adjust the height of feeding line.
t) Lubrication type: lubrication grease, manual grease bump lubrication

Customer’s Application

Compact decoiler straightener feeder machine is working in customer’s factory.


1. What’s payment terms?

SUNRUI MACHINE receives T/T payment and LC at sight when the amount over USD15000.00.

2. What’s your coil equipment leading time?

For standard decoiler, straightener or feeders, the usually lead time is about 10-25 workdays, but we usually have machines in stock. Please contact with our sales if you need the coil handling equipment urgently.

For compact coil feed lines or whole metal stamping lines, it needs 30-70 workdays depends on different specifications and production plan in our factory.

3. What’s warranty time of your machine?

Usually the warranty time is 12 months. Also the warranty time can be extend acorrding the specific requirements.

4. What after-sales service does SUNRUI provide?

For the standard decoiler straightener feeder machine, it’s easy to install and debug it, most of our customers can do it by themselves; And what’s more, our technical engineer can teach your operators how to install  and operate it. SUNRUI machine on-site training will avoid operational problems that are easy to occur at the beginning of production. The training after sales service will create more value for your employees.

For the compact coil feed machine and complete metal stamping line, SUNRUI can arrange engineers to go overseas for the coil handling equipment installation. They guide the customer’s operators on-site. Then the commissioning phase will smoothly enter into the mass production phase.

5. What’s the package of your coil feeding machine?

For standard small decoiler, straightener, feeder which go LCL shipping, SUNRUI machine will use plastic films cover the equiment, and then fix it into a woodencase.

For the coil feed lines and complete line which go FCL shipping, SUNRUI machine will fix each part with ropes on the shipping container and then wrapped them with plastic films.
