Vertical Bagger Problem Observed – Short bags, inconsistent bag lengths, or difficulty holding print registration
Possible Reason – Film Feed Belt Slipping
Cause and Solution:
- Belts are dirty.
- Clean the belts by wiping them with a damp cloth
- Belts are worn. Visually inspect the belts for wear.
- Typically this can be seen by the belt being worn in the profile of the shape of the tube. If there is wear, then replace with new belts.
- Belts are misaligned.
- Check that the belts are parallel to the tube and to each other.
- Check that the belts are on the same center line of the tube from front to back
- Increase in film drag.
- Check that the film is properly threaded through the rollers.
- Check that a part of a film splice did not get caught between the collar and the tube and causing increased drag.
- Not enough pressure on the film feed belts.
- Increase the pressure via the method designed with your model machine,( i.e. air pressure or spring pressure)
- Film feed vacuum not adequate.
- Check that the vacuum setting is turned on as described in the operations manual.
- Check that the vacuum system is working correctly by ensuring that both the filter and tubes are not clogged in any way.
- Servo coupling is loose or broken causing inconsistent belt motion.
- Inside the housing of the vertical bagger, inspect the coupling and make sure it is intact and that is not broken or loose.
