Troubleshooting delamination issues on the corrugator

the roll gets smaller. If the splicer is not set up correctly and too much brake is released before the roll decreases in size, this will also cause a lack of tension and white glue lines can appear. If the roll chucks are not kept clean and the roll slips on them then the brakes are not allowed to operate correctly and delamination can occur.
