HE GLK4 Decoiler Straightener Feeder Features

Automatic Coil Threading

It adopts adjustable coil guide rollers and pneumatic coil hold-up arm for smoothly coil threading. The pneumatic swing device prevents coil upwards, and leading material enters into straightening part gently.

Wide Range Material Processing

The compact line HE GLK4 series is capable of handling material thickness from 0.6mm to 6.0mm. It is suitable for a variety kind of automotive parts stamping. The maximum applicable coil width can reach 1800mm.

Back-up Rollers for Precision Straightening

Adopt with back up rollers, HE 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.

Variety control system for option

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

Reliable Machine Structure

The main body of the decoiler straightener feeder machine is processed in our CNC workshop. Multiple treatments make it a reliable tool and long-lasting service. Rigid frame providing stable work for progressive metal stamping or laser cutting process.

Workspace Saving and Safety Operation

Compare to the traditional structure; the compact 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, protects operators and saves labor costs.
