I. Main features
1. This high strength GLK4-H series coil feeding machine combines decoiler, straightener, and NC servo roller feeder together, so as 3 in 1.
    As an integrated structure design, it can save workshop space obviously, as does not require a long metal sheet strip loop control.

2. It is a high intelligent machine, with a servo control system, a human–computer interface, and a self-diagnosis function etc.,
    for convenient and safe operation, besides can protect users’ safe in press workshops.
3. It has a strong body structure with a reliable usage and a long service life indeed, special for high strength metal sheet material stamping,
    such as automotive parts etc.
4. An automatic supporting device and an automatic guiding device can support and guide applicable metal sheet strip into the straightener entrance easily.

5. Its straightening rollers are made of high-quality steels, with special heat treatment, with hardness HRC62 and high abrasion performance.
    The upper rollers position can be adjusted by some worm gears easily.
    Through a servo motor drive, it can ensure a high precise straightening performance.
6. Some back pressure rollers can exert some powerful force for the upper straightening rollers and lower straightening rollers,
    in order to achieve straightening rigidity and performance.

7. Through the servo motor drive and pneumatic pilot releasing, it can bring a precise feeding performance.

8. It can suit for various metal sheet coil material, such as high strength steel, cold rolled steel, hot rolled steel, galvanized steel etc.

9. Its coil car is optional, which can load a material coil to the decoiler automatically.

10. Other optional devices and non-standard devices can be equipped for your special requirement.
