Causes
- Adhesion of the product to the roll cover
- High temperature load
- Static charge
- High contact pressure
- High production speeds
Effects
- Melting and cracks in the cover
- Wrinkles in the product
- Damaged products
- Core detachment of the cover
- Impurities in the product
The lamination of films onto steel, stainless steel or non-ferrous metal takes place at high temperatures, whereby the lamination roll coatings are subjected to high stress. Depending on the coating used, it melts, cracks or becomes slippery smooth.
High contact pressure and / or high circumferential speeds often result in damage to the lamination roll coating, for example, due to marks or detachment of the cover.
