Coil Straighteners in the Manufacturer's Catalogue
A coil straightener — a levelling machine — removes coil set by passing the strip through staggered rollers before it reaches the feeder and die. The manufacturer's platform catalogue documents the straightening branch in combined listings — straighteners built with an uncoiler, and levelling sections inside 2-in-1 and 3-in-1 combined units; the figures below are those listings' published data. The combined-unit data also appears on the coil feeding lines page, and the machines that feed from the straightener are on the servo feeder and roll feeder pages.
| Item | Published catalogue data |
|---|---|
| Straightener with uncoiler — material | Thickness 0.5-3.2 mm; coil width 20-600 mm; coil weight under 3 tons |
| Straightener with uncoiler — materials listed | Cold-rolled steel, hot-rolled steel, galvanized steel, stainless steel, aluminium |
| Straightener with uncoiler — feed speed | 0-20 m/min |
| NLF2 levelling section | 11 levelling rollers; material window 0.3-3.2 mm |
| 3-in-1 levelling adjustment | Worm gear levelling adjustment with straightening rollers (combined unit listing) |
| 500 mm uncoiler-straightener | Combined decoiler-straightener structure for 500 mm coil sheet lines |
What the Listings Describe
The straightener-with-uncoiler listing describes the combined structure's purpose in floor terms: it reduces the material loop between uncoiling and levelling, which it states saves 3-5 m of space in the press workshop, and synchronises the decoiler and straightener by construction. Its levelling section uses a pneumatic rod pressing and release system on the upper rollers, with the roller gap adjusted by handwheel — on this listing, by turbine shaft and handwheel — and the straightener part opens for regular maintenance. The 500 mm uncoiler-straightener listing describes the same combined principle for 500 mm coil sheet stamping lines, and the 3-in-1 combined unit listing adds worm-gear levelling adjustment across its 0.3-4.5 mm material window.
The Combined Forms in the Listings
- Combined uncoiler-straightener: the listing states the combined unit reduces the material loop between uncoiling and levelling, which saves 3-5 m of space in press workshops, with synchronisation between decoiler and straightener built into the combined structure.
- Straightening inside a 3-in-1 unit: decoiler, straightener and feeder under one control — the NLF2 pattern, 11 levelling rollers over a 0.3-3.2 mm window.
- Roller count is the working figure: more levelling rollers work the strip through more bends; the catalogue publishes 11 on the NLF2. The count for a specific combined configuration is confirmed in the quotation, not assumed from the family name.
A straightener is specified against the coil, not the press: width, thickness range, material and coil weight are the enquiry inputs, and flatness requirements belong in the same message. The catalogue's main press models carry a documented minimum order of one piece; feeding equipment is quoted per configuration.
Frequently Asked Questions
What material window do the straightener listings cover?
The straightener-with-uncoiler listing publishes 0.5-3.2 mm thickness and 20-600 mm coil width with coils under 3 tons; the NLF2 combined unit covers 0.3-3.2 mm, and the 3-in-1 combined unit 0.3-4.5 mm.
How many levelling rollers does the straightener have?
The NLF2 listing publishes 11 levelling rollers. Roller counts for other combined configurations are confirmed in the quotation.
Which materials are listed for the straightener?
Cold-rolled steel, hot-rolled steel, galvanized steel, stainless steel and aluminium, per the straightener-with-uncoiler listing.
Does combining the uncoiler and straightener really save floor space?
The listing states the combined structure reduces the material loop between uncoiling and levelling and saves 3-5 m of workshop space — the catalogue's figure, quoted as published.
