Folding rollers are essential for achieving clean and precise folds.
The challenge is that wear is often not immediately visible.
In practice, a typical pattern appears. If the same format is used over a long period of time, the rollers do not wear evenly. The area where folding happens constantly is used much more, while other areas remain almost untouched.
One clear sign is the difference in material thickness towards the metal core. In heavily used areas, less material remains, which directly affects folding quality. Results become less consistent, and the machine is put under more stress.
Not every sign of wear requires immediate replacement. However, once quality starts to drop and consistent results are no longer possible, the rollers should be replaced.
New folding rollers are an investment, but they ensure that the machine runs smoothly and reliably again.
conclusion
Uneven wear on folding rollers is a common issue, especially when running the same formats continuously. Regular checks and timely action help avoid quality problems and unnecessary machine wear.
