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, and converting. Cleaning systems may use contact or non-contact methods, including airflow extraction, ionisation, and filtration.
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]
