3-in-1 Servo Decoiler Straightener Feeder for Medium-Thick Plate (0.6-6.0mm)

The NLF3 is a 3-in-1 decoiler straightener feeder for medium-thick plate from 0.6 to 6.0 mm. It combines decoiling, straightening and precision feeding in one compact unit that installs without a pit and saves floor space.

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 medium-thick coil feeding.

The NLF3 processes hot-rolled, cold-rolled, galvanized and stainless steel coils from 70 to 1600 mm wide and up to 15000 kg. Hydraulic coil expansion, a servo feed motor (4.4-15 kW by width) and touchscreen PLC control deliver ±0.15 mm accuracy at 16-24 m/min.

Applications

Automotive structural and chassis part stamping
Heavy machinery and engineering parts
Medium-thick and medium-high-strength steel coil feeding
Appliance and electronics hardware stamping
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, usually under 5 m long, installing without a pit.

Medium-Thick Plate Handling

Up-4/down-3 work rolls plus a back-pressure roll set deliver flat, stable feeding.

Servo Precision Feed

Servo motor scaled by width (4.4-15 kW) achieves ±0.15 mm accuracy.

Hydraulic Coil Expansion

Hydraulic expansion ensures secure coil loading and fast changeover.

PLC Touchscreen Control

Integrated control with stored, recallable settings for simple operation.

Line Integration

Pair the NLF3 3-in-1 feeder directly with a press for medium-thick plate stamping. Compare with our servo NC feeders and handling robots for a complete line.

FAQ

What thickness can the NLF3 handle?

0.6 to 6.0 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.

How accurate is the feeding?

±0.15 mm feed accuracy via an AC servo feed motor.

Does it need a foundation pit?

No. The compact 3-in-1 design installs without a pit and is usually under 5 m long.
