Troubleshooting Tips: Worms

Worms are a formation defect resulting from strings of improperly dispersed fiber.

They can be caused by an incorrect slice setting, excessive water from the breast roll shower, and poorly set deckle boards.  They can also be caused by an improperly set forming board and too high of a total head.

Once the source of the worm issue is identified the proper adjustments should eliminate the worming.  If the source is not known, carefully adjust probable cause areas to identify the source.  Of course, you should go through the adjustments that would cause the least possibility of a break before the ones that are more likely to cause a break.

This is a fairly straight forward process.  The backtender or quality person should be the ones who detect the worms.  The wetend should be notified to find the cause and rectify the situation.
