1 · Strip specification

Width + Thickness + Strength

Start with the actual grade and yield strength, then find the model with adequate width at the required thickness.

2 · Coil handling

Weight + Inside / Outside Diameter

Match the loaded coil to the selected machine and expansion arrangement. Coil load capacity alone does not define the permitted coil dimensions.

3 · Production demand

Speed + Buffer + Feeder

Review feed pitch and press speed alongside average strip demand, outlet-loop space and the selected NC feeder.

Coil restraint and leveling control

Machine Features for Medium-Thick Material

The described UL-C configuration uses a pneumatic press arm, a braked non-motorized reel, worm-gear adjustment and a VFD-controlled leveling drive. Each function addresses a different part of material preparation.

Standard coil restraint

Pneumatic Press Arm

The arm helps restrain the outer wraps during coil handling, threading and pay-off. Set it for the actual coil and loading procedure, especially where thicker strip tends to spring back.

Worm-Gear Adjustment

The adjustment mechanism provides mechanical advantage when setting the head under higher leveling loads. Use controlled changes and inspect the outgoing material against the required flatness.

VFD Speed Control

The speed setting adjusts material delivery through the leveling section. Review supply speed with the outlet buffer and feeder demand; feed-length control belongs to the downstream feeder.

Mandrel Expansion and Pay-Off Control

The mandrel grips the coil bore. In the described standard arrangement, the reel is non-motorized and uses an adjustable mechanical brake to help limit overrun as the leveling head draws strip.

Optional handling upgrade

Hydraulic Mandrel Expansion

Hydraulic expansion reduces manual effort when gripping and releasing the coil bore. Consider it according to coil weight, inside diameter and changeover frequency, within the selected machine’s load rating.

Setup and material care

Adjust, Inspect and Record

Check incoming coil condition, roller cleanliness and strip guidance before production. Record useful settings with grade, width and thickness so repeat jobs have a clear setup reference.

Configuration photographs

Inspect the Frame, Head and Operator Side

These existing machine photographs show different builds and control arrangements. Use them to review access and overall construction; the specification table defines the quoted UL-C model.

Review the Coil and Control Positions

Check the reel, head and cabinet positions against the intended loading direction and available aisle space. Accessories and appearance vary by build.

Keep Controls and Setup Accessible

Plan a clear operating position with access to head adjustment, the coil support and the control cabinet. Confirm the arrangement in the final layout drawing.

Configuration confirmation

Specify the Machine Around the Job

Confirm the UL-C model, coil dimensions and weight, material capacity, site power and selected expansion method. Include the press-side feeder and any control-interface requirements.

For commissioning and routine maintenance, follow the documentation supplied with the actual machine. Stop and isolate the equipment before accessing rollers, gearing or other moving components.

Press-line integration

Plan Loading and Maintenance Routes

The production-floor view shows why coil supply, press positions and clear working routes must be planned together. Confirm the UL-C layout using the actual site dimensions.

Hardware components

Hinges and Structural Brackets

Review thicker hinge and bracket materials against the capacity table. Check incoming shape and the required flatness for the subsequent forming operation.

Automotive components

Seat Tracks and Support Parts

Select from actual material strength and strip dimensions. High-strength automotive grades require a capacity review beyond the mild-steel reference table.

Construction fittings

Mounting and Connection Hardware

An integrated line can prepare coil strip for fittings and supports. Match the model to coil load, permitted strip width and the production layout.

Choose the range that fits the material. Compare UL / UL-A for general 0.35–2.2 / 0.35–3.2 mm work, or PUL precision 2-in-1 machines for thin-strip precision leveling. Each range has its own capacity and configuration.

FAQ

UL-C Selection and Operation Questions

How does UL-C differ from standard UL and reinforced UL-A?
UL-C is the medium-thickness, heavy-duty 2-in-1 range listed for 0.5–4.5 mm material, with models from 200 to 800 mm and coil loads from 2,000 to 5,000 kg. Standard UL is listed for 0.35–2.2 mm and reinforced UL-A for 0.35–3.2 mm. Select each family using its own width-thickness capacity table and material strength.
Can UL-800C process 800 mm wide strip at 4.5 mm thickness?
The published reference allows 800 mm width at 1.5 mm thickness, but 450 mm width at 4.5 mm thickness for UL-800C. These values apply to material with yield strength no greater than 235 N/mm². Maximum width and maximum thickness must be checked as a combination.
Is the uncoiler section motorized?
The described standard UL-C arrangement uses a non-motorized uncoiler with an adjustable mechanical brake. The leveling section pulls material from the coil. The brake helps control coil overrun, while the VFD adjusts the leveling drive speed.
Why does UL-C use a pneumatic press arm?
The pneumatic arm helps restrain the outer coil wraps during handling, threading and pay-off. This is useful when thicker material tends to spring back. The arm is listed as a standard UL-C feature; its setup must suit the actual coil and loading procedure.
What does worm-gear adjustment do?
The worm-gear mechanism gives operators mechanical advantage when adjusting the leveling setting under higher loads. Use the handwheels to set the head for the actual material and inspect the outgoing strip. The adjustment mechanism alone does not specify a finished flatness tolerance.
Is hydraulic expansion available?
Hydraulic mandrel expansion is available as an option to reduce manual effort when gripping and releasing the coil bore. Select it according to coil weight, inside diameter and changeover frequency. The final coil load rating remains the rating of the selected machine.
Can UL-C handle high-strength steel?
High-strength material requires a separate capacity review. The published width-thickness table is based on yield strength up to 235 N/mm². Send the actual grade, yield strength, width, thickness, incoming coil condition and target flatness so a suitable configuration can be assessed.
Does the 2-in-1 machine provide servo feed-length control?
The two integrated functions are decoiling and leveling. In a stamping line, an outlet buffer normally supplies a separate NC servo feeder, which controls the feed pitch and coordinates delivery to the press. Match the buffer and supply speed to that feeder and press.
What information is needed for a quotation?
Provide material grade and yield strength, width and thickness ranges, coil weight and inside/outside diameters, flatness and surface requirements, feed pitch, press speed, available space, loading direction and site power. Include any hydraulic expansion or control-interface requirements.
