3-in-1 Servo Decoiler Straightener Feeder for Medium-Thin Plate (0.2-3.2mm)
The NLF1 is a 3-in-1 decoiler straightener feeder for medium-thin plate from 0.2 to 3.2 mm. It combines decoiling, straightening and precision feeding in one compact unit with a short, single material path.
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-thin coil feeding.
The NLF1 processes cold-rolled, galvanized and stainless steel coils from 50 to 800 mm wide and 3000 to 5000 kg (7000 kg optional). Six upper and five lower work rolls provide fine thin-sheet leveling, with ±0.15 mm accuracy at 16 m/min.
Applications
- Electronics and appliance thin-sheet stamping
- Hardware stamping parts
- Automotive thin-sheet part stamping
- Medium-thin plate coil feeding
- 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 material path from coil payoff to feeding, installing without a pit.
Medium-Thin Plate Handling
Up-6/down-5 fine work rolls provide precise thin-sheet leveling.
Servo Precision Feed
