For producing a creped material, especially a sealing material for connections and transitions on buildings, with this material being provided with crepe folds, wherein the crepe folds run in different directions, a method is disclosed with the steps of: a) preparing a deformable material web () with a main expansion direction (); b1) forming a longitudinal profile () in at least one region of the deformable material web (), wherein the longitudinal profile runs essentially parallel to the main expansion direction (); c) forming a transverse profile () in at least one region of the deformable material web (), wherein the transverse profile () runs at an angle other than 180&#xb0; relative to the main expansion direction (); and d) pressing at least one section of the deformable material web () that has at least one region with a longitudinal profile () and a transverse profile (), so that the material web () is provided with the crepe folds. Roller arrangements for performing the method are also disclosed.
