Problem: STRIPE ON THE LAMINATED SHEETS RUNNING ACROSS
Solution: The stripe running across is caused by the decurling bar.
The cause can be removed:
- By turning the decurling bar to the larger radius position
(Changing the decurling bar radius is described in Chapter 13.2)
- By increasing the pressure on the pull rollers where the sheets slide between the pull
rollers when they are separated (an adjustment of pull roller pressure is described in
Chapter 13.2)
Problem: IF POLYPROPYLENE FILM IS USED, THE SHEET WEB SPLITS BETWEEN THE
LAMINATING SECTION AND SEPARATOR
Solution: The problem is caused by excessive tension by the pull rollers.
The cause can removed:
- By reducing the separator pull rollers pressure (Adjustment of pull roller pressure is
described in Chapter 13.2)
