Method for changing the format in a corrugated board manufacturing plant

摘要

The method involves using two groups of cutter tools (14,15) to form first and second external longitudinal cuts and first and second internal longitudinal cuts along the conveying direction of a corrugated cardboard web (2). The first and second external longitudinal cuts overlap each other in pairs along the conveyance direction (3), while the first and second internal longitudinal cuts overlap each other along the conveying direction. An internal connecting cut connects the first and second internal longitudinal cuts, while extending crosswise of the conveying direction. Two external connecting cuts connect the first and second external longitudinal cuts while extending crosswise of the conveying direction. The external connecting cuts end before the side margins of the corrugated material web.
