How to avoid bending of PVC conveyor belts

1. The thickness of the two sides of the PVC conveyor belt is different. The thick side is easier to stretch than the thin side, which will cause the length of the two sides to be inconsistent, causing bending.
2. The two sides of the tape are inconsistent, resulting in different tightness, so the conveyor belt will also bend.
3. The clamp is not controlled well and is not in a straight line with the main machine, which will also cause bending.
