Solventless Laminator Setup and Mix Ratio Inspection

Pre-run inspection template for solventless laminator setup. Verifies metering pump ratios, application temperature, coat weight, web path readiness, and safety controls before bonding multi-layer structures.

Machine Identification and Setup Authorization

• Machine ID, line number, and job order are recorded
  Capture the solventless laminator identifier, production line, and work order or batch number for traceability.
• Setup is authorized for the current job and material combination
  Verify the setup matches the approved job ticket, substrate combination, and adhesive system before startup.
• Current SOP, recipe, or setup sheet is available at the machine
  Approved setup instructions must be present and accessible to the operator or inspector.

Adhesive Mix Ratio and Metering System

• Metering pump ratio matches the approved recipe
  Record the actual metering pump ratio and compare it to the target ratio specified for the job.
• Component A / Component B mix ratio is within tolerance
  Enter the measured mix ratio for the adhesive components and confirm it is within the approved tolerance window.
• Metering pumps, hoses, and filters show no leaks or visible damage
  Inspect the adhesive delivery path for leaks, cracks, loose fittings, or other non-conformances.

Application Temperature and Coat Weight

• Adhesive application temperature is within target range
  Record the adhesive application temperature at the applicator or control point.
• Coat weight is within specification
  Measure and record the applied coat weight against the approved product specification.
• Temperature and coat weight readings are documented at startup
  Confirm the initial process readings were captured before the run was released.

Web Path, Substrate, and Bonding Readiness

• Web path is threaded correctly and aligned
  Verify the web path, rollers, and guides are threaded according to the approved setup and are aligned for the run.
• Substrates are correct, clean, and free of visible contamination
  Confirm the materials loaded match the job and show no visible dust, oil, moisture, or other contamination.
• Nip pressure, tension, and unwind/rewind settings are set to specification
  Verify key mechanical settings are within the approved setup parameters for stable bonding.

Safety, Housekeeping, and Regulatory Controls

• Machine guards, interlocks, and emergency stops are functional
  Confirm guarding and emergency stop devices are in place and operational before the machine is released.
• Lockout-tagout status is verified for maintenance or setup work as required
  Verify OSHA 1910.147 lockout-tagout controls were applied when maintenance, cleaning, or adjustment required energy isolation.
• Area is free of spills, trip hazards, and obstructed access to emergency equipment
  Check the immediate work area for housekeeping deficiencies and clear access to emergency equipment and exits.
