The end of the original membrane is damaged or notched. 2. There is a hole in the middle of the original membrane. 3. The joint is not completed. 4. Uneven tension (too large). The air pressure of the unit impression cylinder is inconsistent. Solutions: 1. Carefully check whether the end surface of the original film is in good condition before winding. If it is damaged, it should be removed or replaced. 2. Re-thread the film after the film is broken. If there are two holes in the same roll, replace the original film. The defective original film shall be returned to the warehouse. 3. Strengthen technical training of personnel 4. Appropriate adjustment (reduction) of tension 5.
