When installing a conveyor belt, it is important to use sufficient pre-tension. If the pre-tension is too low, you lose grip on the drive after the fabric has been relaxed and it may slip. For a conveyor belt with PET fabric, the pre-tension at installation is at least 0.3% (0.5% for PA fabric), which is usually sufficient for correct operation.
