1. Edge wear: Caused by friction between the belt and the frame due to misalignment, resulting in thinning of the edges and exposed fibers.
2. Longitudinal tear: Caused by scratches from sharp objects, damaged idlers, or snagging due to misalignment, forming a through-cut tear.
3. Cracking: Surface cracks caused by frequent bending or repeated vulcanization joints.
4. Damage to the cover rubber surface: Improper guide plate clearance, material impact, or scratches from the cleaner cause the rubber layer to peel off.
5. Joint tearing: Reduced strength at the joint due to poor vulcanization quality or an insufficiently small roller diameter.
