Error 20.x Double-sheet too late
Description
On the rollformer, a double sheet was detected so late that the double sheet switchpoint could not be deflected before the sheet arrived. The sheet would have been jammed by the switchpoint.
Remedy
- Re-adjust the feeder.
- Check the pull-in roller pair for fouling.
- Check the roll gap of the pull-in roller pair (sheet thickness - 0.05 mm).
- Replace the suction elements.
- Check rounding station locking mechanism (machine 800-1000).
