In order to prevent the occurrence of tear outs in splicer defects, it's important to exercise caution when aligning the new roll with the running web. If the leading edge of the new web is not inserted properly, any side-wise movement of the roll stand can cause a diagonal stress, leading to a tear out during splice actuation. To avoid this issue, it's recommended to apply adhesive transfer tape to the bottom edge of the preparation bar and cut the paper flush across the bottom edge of the paper bar while trimming the corners back at a 45-degree angle. This helps reduce tension and prevents the tape from being applied too high or unevenly across the web.

To ensure proper splice reliability, it's important to remove the tape backing just prior to splice actuation and avoid allowing dust to accumulate on the tape. Furthermore, it's recommended to index the web as required by the manufacturer to ensure correct placement of the prepared web. By following these precautions, you can prevent tear outs and ensure a smooth splicing process.
