Why combine the two functions?

Precision Leveling in Less Floor Space

A separate decoiler and leveler each require their own installation position. PUL brings both functions onto one base, making coil preparation easier to arrange beside a press line.

01 · UnwindThe decoiler supports the coil and releases strip.

02 · LevelThe precision roller head corrects incoming coil curvature.

03 · Buffer + FeedAn outlet loop supplies a separate feeder that controls the feed pitch.

04 · StampThe feeder delivers the prepared strip to the press tooling.

Compact installation

Coil Reel and Leveler on One Base

The loaded-coil view shows how the reel and leveling head share the machine body. This arrangement is useful when the press area has limited space.

Material path

Guide the Strip from Coil to Leveler

The strip follows the guide path from the coil into the precision leveling head, then forms an outlet loop for the downstream feeder. Loop sensing coordinates material supply.

Plan the complete working area. Allow access for loading coils, opening the leveling head, maintenance and the outlet buffer loop. Required space depends on the selected machine and press-line arrangement.

Roller diameter and material thickness

Leveling-stage configuration

Pre-Leveling Followed by Fine Leveling

A dual-stage head divides the correction into two successive sections. Select it when the incoming coil curvature benefits from preliminary correction before fine leveling.

Dual-stage PUL configuration

Two Sections Along the Material Path

Pre-leveling: the first section reduces the main incoming coil curvature and prepares the strip for the next section.

Fine leveling: the following section applies further controlled alternating bends to refine the outgoing strip condition.

Set the sections for the actual thickness, strength and incoming strip condition, then inspect the result. The photograph shows the dual-stage configuration; its complete roller layout is specified for the ordered machine.

“2-in-1” describes decoiling plus leveling. “Dual-stage” describes the arrangement within the leveling function.

Setup and access

Open Head with Dial Indicators

The head opens above the material path for inspection and cleaning. The dial indicators provide a reference for adjustment movement and repeat setup.

Adjustment choices

Standard Four-Point Independent Adjustment

The listed configurations use four-point independent adjustment. Make small changes to the leveling setting and check the outgoing strip against the required result.

Record useful settings with the material grade, thickness and width. A dial indicator shows adjustment position; finished flatness is checked on the material.

Optional for thicker material

Four-Point Worm-Gear Adjustment

The worm-gear mechanism provides greater mechanical advantage for applying leveling pressure and makes adjustment easier when processing thicker material within the chosen machine’s capacity.

Select this upgrade according to the material and adjustment load.

Sensing and gear lubrication

Three Options to Match Your Production Routine

Choose the sensing method and lubrication arrangement for the material and operating schedule. These options are separate from the roller diameter and the four-point adjustment upgrade.

Option 1 · Loop sensing

Dual Photoelectric Sensing

Photoelectric sensing is fitted at both the decoiler and beneath the leveler outlet loop. This adds non-contact outlet sensing in place of the standard contact-type arrangement.

Option 2 · Operator-actuated lubrication

Foot-Operated Manual Grease Pump

Press the foot pedal to supply lubricant through connected lines to the gear lubrication points. Regular lubrication helps reduce wear and supports longer gear life.

Option 3 · Automatic lubrication

Fully Automatic Gear Lubrication

The automatic system supplies lubricant to the connected gear lubrication circuit without repeated manual pumping. Check lubricant level and delivery lines as part of routine maintenance.

Standard sensing

Photoelectric at Decoiler + Contact at Outlet

The standard machine uses photoelectric sensing for decoiling and contact-type sensing after the leveler discharge. Choose dual photoelectric sensing when non-contact detection is also required at the outlet.

Standard preparation

Gears Greased Before Dispatch

The gears are greased before the machine leaves the factory, including machines ordered without the optional manual pump. Follow the machine’s inspection and lubrication schedule during use.

Gear lubrication and strip oiling serve different purposes. The manual pump and automatic lubrication options service the machine’s gears. Oil applied to the strip for the stamping process is a separate requirement.

FAQ

PUL Configuration Questions

What does 2-in-1 mean on the PUL machine?

It combines decoiling and precision leveling on one compact machine base. The decoiler pays off the coil and the leveling head corrects the strip before it goes to a separate feeder. A downstream NC or other suitable feeder controls the feed length for the press.

Why choose an integrated decoiler leveler?

Choose PUL when you need precision leveling and want to reduce the installation footprint of separate decoiling and leveling machines. The final line still needs room for coil loading, head opening, maintenance and the outlet loop before the feeder.

Which roller diameter suits my material thickness?

The listed 200-20 configuration uses Ø20 mm work rollers for 0.1–0.6 mm material. The 200-32 uses Ø32 mm work rollers for 0.3–1.5 mm material. Regular working-width models are 200, 300 and 400 mm. The detailed 200-20 and 200-32 table gives the 200 mm configuration data; motor power, speed and coil capacity for wider models are confirmed for the selected build. Grade, temper, strength, surface requirements and flatness targets are also checked during selection.

Does dual-stage leveling mean a different number of combined functions?

No. Two-in-one refers to the two machine functions: decoiling and leveling. Dual-stage refers to a preliminary leveling section followed by a fine-leveling section along the material path. The stage layout is specified separately from the two configuration columns in the specification table.

What sensing is supplied as standard?

The standard arrangement uses photoelectric sensing at the decoiler and contact-type sensing after the leveler outlet. Dual photoelectric sensing is optional: it retains the decoiler photoelectric sensor and adds a photoelectric sensor beneath the leveler outlet loop.

How is the manual grease pump operated?

The manual grease pump is operated by pressing a foot pedal. It supplies lubricant through connected lines to the gear lubrication points. It helps keep the gears lubricated and supports longer service life. Without this option, the gears are greased before dispatch; routine inspection and later lubrication still follow the machine maintenance instructions.

What does the fully automatic lubrication option do?

It supplies lubricant automatically to the connected gear lubrication circuit, reducing the need for repeated manual pumping. It lubricates the machine gears; applying process oil to the strip is a separate function. The reservoir and delivery lines still need routine checks.

When is four-point worm-gear adjustment useful?

It is an optional adjustment upgrade for thicker material within the selected configuration’s capacity. The worm-gear mechanism provides greater mechanical advantage for applying leveling pressure and makes adjustment easier. Standard four-point independent adjustment and optional worm-gear adjustment are different configurations.

Can the leveling head open for cleaning?

Yes. Both listed 200-20 and 200-32 configurations have an openable head for access to the work rollers. This makes inspection and cleaning easier. Keep the roller surfaces clean and set the machine for the material; surface acceptance should be checked on a representative sample.
