Companies
1. Increase refining.
2. Increase refining consistency.
3. Run couch and press draws as slack as possible.
4. Reduce tension in dryer felts.
5. Run sheet moisture as high as possible.
— a high moisture contributes to a high stretch.
6. Check sheet formation.
— a well closed sheet contributes to high stretch.
— square the sheet on the forming table of paper machine.
Note: To square the sheet on the forming table of a paper machine, you would need to adjust the alignment of the sheet so that it is straight and even on the table. This can be done by adjusting the guides and edges of the forming table to ensure that the sheet is evenly distributed across the width of the table. Additionally, any wrinkles or unevenness in the sheet can be smoothed out using a flattening roller or other equipment specifically designed for this purpose.
