Features


Wide Range Material Processing

The compact coil feeding line GLK4 series is capable of handling material thickness from 0.6mm to 6.0mm, which is suitable for a variety kind of automotive parts stamping. The maximum applicable coil width can reach 1800mm. And there is also advanced version GLK4-H for high strength steel coil handling.


Automatic Coil Threading

This decoiler straightener feeder series adopts adjustable coil guide rollers and pneumatic coil hold-up arm for smoothly coil threading. The pneumatic threading assists swing device prevents coil upwards, and leading material enters into straightening part gently. HE also provides a fully automatic control option with handsfree loading and electric adjustment.


Back-up Rollers for Precision Straightening

Adopt with back up rollers, GLK4 series has back up rollers on the top and bottom of the straightening rollers. These groups of back up rollers will carry the separating force loads to achieve better straightening performance.

Reliable Machine Structure

The main body of the decoiler straightener feeder machine is processed in our CNC workshop by multiple treatments to make it reliable and long-lasting service. Rigid frame providing stable work for progressive metal stamping or laser cutting process. It eliminates the deflection of the sheet metal coil with a unique straightening structure.


Workspace Saving and Safety Operation

Compare to the traditional structure; the combined coil feeding line reduces the workplace from 15m to 5m. And the highly integrated control system is easy to operate and maintain. It provides automatic coil loading, which protects operators and saves labor costs.


Variety control system for option

Mitsubishi, Siemens, and ABB servo control systems are our standard options, and we also provide customized control system service.
