One blank-corner is damaged when touching the inner catch rail.
Summary
The damaged/bended corner is touching first the inner catch rail.
The inner catch rail looks like a hook and will be found underneath the lower rollformer shaft on the catch station.
By changing the horizontal level of the catch channel slightly, the roll-forming direction of the tin plate will be changed/affected, and the whole tin plate edge should touch the catch rail equally.
- Measure the inner left and right distance between the hard-chromed guidance channel and internal hard-chromed guide-shell (around lower rollformer shaft). The left/right measures are most probably not equal.
- Try to correct one of the distance until both measures are equal. If you are not sure how to correct, feel free to contact us via the online support system.
