Causes
- Demanding plowing patterns
- High process speeds
- Increased deflection of older embossing cylinders
Effects
- Inaccurate embossing
- Insufficient embossing
- Different embossing intensities
- Insufficient volume of embossed rolls
When embossing tissue and hygiene papers, the combination of a high, tightly standing embossing pattern and increased process speed can lead to inaccurate and insufficiently deep embossing. This phenomenon is exacerbated across the web width due to the higher deflection of older cylinders. Due to these embossing errors, insufficient volume is achieved for a given number of sheets.
