Automatic optical systems for measuring the width of flat products, paper sheets, cardboard and films

Automatic optical width measurement systems offer precision and speed for flat products such as paper sheets, cardboard and films. Ideal for in-line inspection, they ensure non-invasive detection and compliance with technical specifications, optimising quality and industrial productivity.

Automatic optical width measurement systems are an advanced solution for the dimensional inspection of flat products such as paper, cardboard and films. Designed to ensure precision and speed, these systems help companies optimise the quality and efficiency of their production processes.

What optical measuring systems are

These systems use high-resolution optical sensors to detect product dimensions precisely. Measurement is non-contact, ensuring reliable inspection even on delicate materials.

Main applications

Paper industry: measurement of paper and cardboard sheets.
Packaging production: inspection of packaging films.
Plastics sector: width verification of technical films.

Operating principle

Optical systems project a light beam onto the moving product and acquire dimensional data via a camera or a linear sensor. These data are processed in real time.

Advantages of optical technology

High precision: micron-level detection.
Non-invasive measurement: preserves the integrity of materials.
Adaptability: works on a wide range of materials and thicknesses.

Integrated instruments

Laser sensors: for fast, precise measurements.
High-resolution cameras: for detailed vision.
Analysis software: for processing and storing data.

Efficiency on the production line

Optical systems can be integrated directly into production lines, enabling real-time inspection without interrupting the workflow.

Automated quality control

Thanks to advanced algorithms, these systems automatically identify any dimensional defects, allowing immediate intervention to correct anomalies.

Reference standards

Optical measuring systems comply with international standards to ensure product conformity, such as ISO 9001 for quality control.

Waste reduction

With accurate width measurement, companies can minimise scrap, optimising material consumption and reducing costs.

Adaptability to different production lines

These systems are modular and customisable, allowing integration into existing lines and adapting to the specific needs of various industrial sectors.

Real-time monitoring

Thanks to digital control panels, operators can constantly monitor measurements and intervene immediately in the event of deviations.

Data management software

The data collected can be stored, analysed and used to create detailed reports, supporting traceability and continuous process improvement.

Maintenance and reliability

Optical systems are designed to be robust and require minimal maintenance, ensuring continuous operation even in complex industrial environments.

Technological evolution

With the adoption of technologies such as artificial intelligence and machine learning, these systems can predict wear trends and optimise production parameters.

Case studies

A film manufacturer implemented an optical measuring system, reducing scrap by 15% and improving production speed by 20%.

Industry challenges

Transparent materials: require specific sensors for accurate detection.
Harsh environments: systems must withstand dust and vibration.

Conclusion

Automatic optical width measurement systems give companies a competitive advantage, improving the precision of quality control and reducing operating costs. Investing in these technologies means ensuring high-quality products and optimised production processes.
