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.

Method and apparatus for marking paper, board and cellulose web rolls

A carriage and track assembly for transferring paper and paperboard rolls along an inclined track. The assembly is useful for the transfer of paper rolls of slippery grades and is based on using a dual track (5, 6) over the length of the inclined section of the transfer track and having compatible wheel sets (3, 4) on the transfer carriage. The front end of the carriage is provided with a wheel assembly (3, 4) in which the rolling perimeter varies at different trackwidths of the assembly. The wheel assembly can be made to run along the inclined sections of said tracks (5, 6) so that in said wheel assembly the rolling perimeters of its wheel sets (3, 4) running on different tracks are vertically located at different heights from the loading platform (1) of the carriage. Thus, the loading platform remains substantially horizontal while the carriage travels along the inclined track.
