2‑in‑1 Uncoiler & Straightener

– Compact, Efficient Coil Processing

The 2‑in‑1 uncoiler & straightener (also called a decoiler leveler combo) is an integrated machine that performs two critical coil preparation functions in one footprint: unwinding the coil and flattening the strip. This eliminates the need for a separate straightener unit, significantly reducing line length and simplifying material handling.

Why choose a 2‑in‑1 design?

In a typical metal forming line, the uncoiler is followed by a separate straightener (leveler). This increases floor space and requires additional alignment. The 2‑in‑1 unit mounts the straightener directly on the uncoiler frame, allowing the strip to pass through leveling rolls immediately after unwinding. Benefits include:

Space saving – Reduces line length by 1‑2 meters.
Lower cost – One combined unit is cheaper than separate machines.
Easier threading – Short material path reduces set‑up time.
Improved flatness – Immediate leveling prevents re‑coiling stress.

Key features:

Motorized uncoiler – Electric motor with inverter, loop control (photo sensor or dancer arm).
Straightener (leveler) – Typically 5‑7 work rolls (upper and lower) arranged to alternately bend the strip, removing curvature and internal stress. Rolls are made of hardened bearing steel (GCr15) or chrome‑plated.
Hydraulic mandrel expansion – Standard for heavy coils; optional manual for light duty.
Pinch roll unit – Motorized pinch rolls pull material from the coil and feed it into the straightener.
Coil car (optional) – Hydraulic lift to simplify loading.

Technical specifications (typical):

Parameter	Range
Coil weight capacity	3‑10 tons (custom up to 25 tons)
Coil inner diameter	450‑520 mm
Coil outer diameter	up to 1300 mm
Coil width	100‑800 mm
Straightener roll count	5/5 or 7/7 (upper/lower)
Roll diameter	50‑80 mm
Straightening speed	0‑15 m/min
Motor power (uncoiler)	2.2‑5.5 kW
Motor power (straightener)	1.5‑3 kW
Loop control	photoelectric or dancer

Operation process:

Coil loaded (coil car or crane).
Mandrel expands hydraulically (or manually) to grip coil.
Strip end is threaded through the straightener pinch rolls.
Straightener rolls are adjusted (motorized or manual gap control) to suit material thickness.
Line speed is set; loop control maintains a small hanging loop between uncoiler and straightener.
The straightener flattens the strip and feeds it to downstream equipment (roll former, press, etc.).

Advantages over separate units:

Reduced floor space – Up to 30% shorter line.
Lower investment – Typically 20‑30% cheaper than buying uncoiler + straightener separately.
Simpler controls – One integrated HMI for both functions.
Quicker setup – No alignment of separate units.

Applications:

Roll forming lines for shelf panels, door frames, cable trays
Stamping press feed lines for automotive parts
Cut‑to‑length lines for flat blanks
HVAC duct forming lines
Solar mounting rail production

Included with the machine:

2‑in‑1 uncoiler & straightener with electrical cabinet
Loop control sensors
Operation manual and spare parts list
12‑month warranty, lifetime remote support

Optional features:

Coil car (hydraulic)
Powered pinch roll (standard on most models)
Quick‑change straightener roll cassette (for different thickness ranges)
Edge guide system
Remote diagnostic module

Maintenance:

Grease straightener roll bearings weekly.
Check hydraulic fluid and filters quarterly.
Clean photo sensors periodically.

Lead time: 30‑45 working days.

The 2‑in‑1 uncoiler & straightener is the ideal choice for manufacturers who want to maximize line efficiency while minimizing floor space and capital investment. It is a workhorse that delivers flat, stress‑free material for high‑quality forming.
