Causes
- Deposit of entrained adhesive mist
- Roll surface not sufficiently anti-adhesive
- Roll surface cannot be sufficiently cleaned
Effects
- Adhesive buildup on roll coating
- Impression roll is damaged at the edge of the product web
- This restricts the working widths that are possible in the future
During adhesive application, adhesive mist is carried from the application unit to the laminating unit. Adhesive residue / adhesive mist remains on the roller surface of the laminating press outside the web width. The tackiness of the deposited adhesive mist increases over time. As a result, tiny pieces tear out of the coating of the impression roller. This effect increases over time. Wider products can no longer be run.
