Abstract
A method and apparatus for automatically marking paper, board or cellulose web rolls at a slitter for the purpose of identifying the rolls during later finishing steps. Such finishing operations include, e.g., roll transport, rewinding, sheeting or other finishing steps and roll packaging. The roll identification code is also used for material management related to customer rolls. The roll identification information of a roll set leaving the slitter, that is, the sequence of rolls exiting from the slitter as a group is transmitted for the use of the roll marking equipment and the customer rolls are moved away from the slitter area only via the roll marking equipment and new rolls are prevented from entering the slitter area in any other form except as a new roll set. As a result, the correct identification data for each roll set is continuously available to the marking equipment.
