Abstract
An arrangement in a cardboard creasing machine, for forming structured patterns of creasing lines in a material comprising a cardboard web fed to the machine, comprising a system of at least two rollers. The first roller is provided with a male die, having at least two envelope surfaces, each with a structured pattern of lines, of which at least one has an open end. In order to prevent wild creasing lines with open ends are provided with crease stoppers, extending perpendicularly to the open line. The second roller is provided with a female die corresponding to the male die.
