Web cleaning is a process used in industrial production to remove dust, fibres and other loose particles from moving webs or sheets. It is applied in the manufacturing and converting of paper, corrugated board, film, foil, nonwoven and other substrates to prevent defects during printing, coating, or other downstream processing operations. Web cleaning systems may use contact or non-contact methods.

Background

[edit]

The need for web cleaning in industrial processes increased as production speeds, volumes, and process complexity grew during the twentieth century. In web-fed processes, loose particles such as fibers and dust may originate from the material itself, from cutting and slitting operations, or from the surrounding production environment.

If this contamination is not removed, it can lead to defects during downstream processing operations, as well as increased equipment wear and maintenance requirements. As production lines became faster and more automated, manual cleaning methods proved inadequate, leading to the development of integrated web cleaning systems designed to operate continuously during production.[1]

Sources of contamination

[edit]

Particles on webs or sheets can originate from several sources, including:

  • fibers or particles released from the material itself during production
  • contamination generated during downstream processes such as cutting, creasing, folding, or stacking
  • electrostatic charge that attracts airborne particles
  • particles generated by wear of machine components, including metals or plastics
  • ambient dust present in open production environments

Web cleaning methods

[edit]

Depending on the application and substrate, web cleaning can be performed using contact or non-contact methods.

Contact systems

[edit]

Contact cleaning systems remove particles through direct contact with the substrate surface, for example, by using elastomer rollers, adhesive rollers, or brushes. These systems are typically applied where the material and surface characteristics allow mechanical contact without damaging the substrate.

Non-contact systems

[edit]

Non-contact cleaning systems remove particles without touching the substrate, typically using controlled airflow, ionisation, and vacuum extraction. These methods are often used in high-speed production environments or when sensitive surfaces require cleaning without mechanical contact.
