Splice failure is a common issue in splicer defects and can be caused by several factors such as low splicing-tape shear strength caused by stress during the splicing sequence or heat-related failure from the preheater or pre-conditioner. If the preconditioner is not driven, it can also lead to splicing issues.

To remedy these issues, it is recommended to remove the wrap arms on preheaters just before splice actuations. Avoid slowing down the corrugator excessively as the splice passes over these heated vessels. Also, do not apply excessive brake on the web before the spliced joint passes over these units. These actions can help reduce stress during the splicing sequence and prevent heat-related failure from the preheater or pre-conditioner.

Additionally, it is recommended to check the splicing-tape shear strength and ensure that it meets the required standards. If low shear strength is identified, the splicing tape should be replaced with a tape that meets the necessary strength levels. Conducting regular quality checks and inspections throughout the production process can also help prevent splicing defects and ensure that the splicer operates optimally.
