What Is a 3-in-1 Decoiler Straightener Feeder?

A 3-in-1 decoiler straightener feeder integrates a coil decoiler, a straightener (leveler) and a servo feeder into a single machine. This design removes the footprint of a separate decoiler-to-leveler connection, ideal for thick and high-strength coil feeding.

The NLF4 processes hot-rolled, cold-rolled, galvanized and stainless steel coils from 70 to 1300 mm wide and up to 10000 kg. Hydraulic coil expansion, a servo feed motor and touchscreen PLC control deliver ±0.15 mm accuracy at up to 22 m/min.

Applications

Automotive structural and chassis part stamping
Heavy machinery and engineering parts
Thick-plate and high-strength steel coil feeding
Appliance and hardware stamping parts
Lines for appliance metal stamping

Straightening Capacity

Maximum corrected width at yield strength σs=245 N/mm² (tensile σb=392 N/mm²). Thicker material allows narrower width — see the thickness-width table for sizing.

Key Features

3-in-1 Compact Design

One unit combines decoiling, straightening and feeding, installing without a pit and saving floor space.

Heavy-Duty Thick Plate

Up-5/down-4 work rolls plus a back-pressure roll set deliver flat, stable thick-plate feeding.

Servo Precision Feed

AC servo feed motor achieves ±0.15 mm accuracy at up to 22 m/min.

Hydraulic Coil Expansion

Hydraulic expansion ensures secure coil loading and fast changeover.

PLC Touchscreen Control

Integrated decoiler, leveler and feeder control with stored, recallable settings.

Line Integration

Pair the NLF4 3-in-1 feeder directly with a press for thick-plate stamping. Compare with our servo NC feeders and handling robots for a complete line.

FAQ

What thickness can the NLF4 handle?

0.8 to 9.0 mm, with maximum width varying by thickness per the capacity table.

What materials does it process?

Hot-rolled, cold-rolled, galvanized and stainless steel coils.
