The HE GLK4 series combined decoiler-straightener-feeder is our best-selling compact-line model. Widely used in automotive parts stamping and white goods production lines, it offers multiple functions with a high-strength version available.

Applicable Material

• Material Thickness: 0.6 mm – 6.0 mm

• Coil Width: 70 mm to 1600 mm

• Coil Weight: 5 ton/7 ton/10 ton/15 ton

Feeding Performance

• Feeding Speed: 0-16 m/min

• Feeding Accuracy: ±0.1 mm

Automatic Coil Threading

It adopts adjustable coil guide rollers and a pneumatic coil hold-up arm for smooth coil threading. The pneumatic swing device prevents coil lifting, guiding material gently into the straightening part.

HE GLK4 Decoiler Straightener Feeder Features

Wide Range Material Processing

The HE GLK4 series compact line handles material thickness from 0.6mm to 6.0mm, suitable for various automotive parts stamping. Its maximum applicable coil width reaches 1800mm.

Back-up Rollers for Precision Straightening

Equipped with back-up rollers (top and bottom of straightening rollers), the HE GLK4 series bears separating force loads for better straightening performance.
