The rolls are arranged in sets of top and bottom clusters, which can be withdrawn from the supporting structure or inserted at one side of the roll rack, the concave side if the rack is curved. Each bottom cluster rests on respective seat fixed within the supporting structure. Each top cluster is held in the supporting structure with keys which are received in openings in straps. Both top and bottom clusters have legs engageable by an extractor for withdrawing or inserting them. |
