  • preparing and feeding strip into the roll forming machine
  • aligning strip and forming stations
  • programming panel length and production quantities
  • operating PLC controls and jog functions
  • testing hydraulic cutting systems
  • inspecting finished liner panels
  • troubleshooting production problems

This manual is intended for:

  • roll forming machine operators
  • steel building manufacturers
  • wall panel manufacturers
  • metal fabrication companies
  • maintenance technicians

1. Machine Overview

A Liner Panel Roll Forming Machine forms flat steel strip into interior liner panels using a sequence of roll forming stations.

Liner panels are typically installed behind exterior panels and insulation systems. They provide structural backing and improve the overall performance of insulated wall and roof assemblies.

Liner panels provide:

  • interior wall protection
  • support for insulation systems
  • improved building durability
  • structural reinforcement for steel buildings

These panels are commonly used in:

  • steel building wall systems
  • interior building walls
  • roof insulation support systems
  • agricultural buildings
  • industrial facilities

Typical Materials Processed

Common materials include:

  • galvanized steel
  • galvalume steel
  • painted steel coil

Interior liner panels usually use light gauge material compared to exterior roofing panels.

Typical Material Thickness

0.30 mm – 0.60 mm

Typical Production Speed

15 – 40 meters per minute

Liner panels typically allow higher production speeds due to simpler profiles.

2. Typical Machine Layout

A typical liner panel roll forming production line includes:

  • Hydraulic Uncoiler
  • Entry Guide System
  • Roll Forming Stations
  • Encoder Length Measuring System
  • Hydraulic Cutoff Shear
  • PLC Control Panel
  • Runout Table or Automatic Stacker

Material flow:

Steel Coil → Entry Guides → Roll Forming Stations → Encoder → Hydraulic Shear → Finished Panels

3. Safety Before Operating the Machine

Operators must perform safety checks before starting production.

Pre-Start Safety Inspection

Before starting the machine ensure:

  • emergency stop buttons function properly
  • machine guards are installed
  • hydraulic hoses are secure
  • electrical cabinets are closed
  • no loose tools are inside the machine

Required Personal Protective Equipment

Operators should wear:

  • safety glasses
  • steel toe boots
  • sheet metal gloves
  • hearing protection

Important Safety Rules

  • never reach between rotating rolls
  • never remove guards while machine is running
  • never stand in front of moving sheet metal
  • stop machine before adjustments

4. How to Load Steel Coil onto the Uncoiler

Step-by-Step Procedure

  1. Stop the roll forming machine completely.
  2. Retract the uncoiler mandrel.
  3. Lift the coil using forklift or overhead crane.
  4. Position the coil directly in front of the mandrel.
  5. Slide the coil onto the mandrel.
  6. Expand the mandrel until the coil is secured.
  7. Center the coil evenly.
  8. Install hold-down arm if available.
  9. Adjust uncoiler brake tension.

What to Watch For

  • coil not centered
  • coil slipping on mandrel
  • excessive brake pressure
  • loose mandrel expansion

Incorrect loading can cause strip tracking problems and panel defects.

5. Preparing the Coil Leading Edge

Before feeding strip into the machine the coil edge must be prepared.

Procedure

  1. Carefully remove steel banding.
  2. Prevent sudden coil expansion.
  3. Inspect the first 300–500 mm of strip.
  4. Cut away damaged material.
  5. Square the leading edge.
  6. Remove burrs if necessary.
  7. Confirm correct paint side orientation.

Why This Step Matters

Damaged strip edges can cause:

  • feeding problems
  • machine jams
  • roller damage
  • poor panel formation

6. Threading the Coil Through the Machine

Procedure

  1. Fully open entry guides.
  2. Feed strip manually into the first roll station.
  3. Ensure strip enters straight.
  4. Use jog mode to slowly pull strip forward.
  5. Continue feeding through each forming station.
  6. Guide strip through the shear section.
  7. Feed strip onto the runout table.

Safety Warning

Never place hands between rotating rolls.

Always use push tools if required.

7. Aligning and Centering the Strip

Correct strip alignment ensures accurate panel forming.

Procedure

  1. Observe strip entering the first roll station.
  2. Adjust entry guides left or right.
  3. Ensure strip runs parallel to machine centerline.
  4. Maintain equal clearance between guides.
  5. Run machine slowly to observe strip tracking.

Signs of Poor Alignment

  • strip drifting sideways
  • uneven ribs
  • panel twisting
  • excessive guide contact

8. Complete Liner Panel Machine Setup Parameters

Before production begins the machine must be configured correctly.

Material Type: Galvanized / Galvalume / Painted Steel
Material Thickness Range: 0.30 – 0.60 mm
