摘要： A strip means for a material web machine, which strip means (2, 3) may be a sealing strip of a suction roll (4), which sealing strip includes a longitudinal strip element (3) and a longitudinal holder (2) of the strip element shaped as a U profile open in the direction of a facing surface (41). The strip element, which is two-layered in a transverse direction with respect to its length, protrudes from the holder and, at least when loaded, is against the facing surface, which moves substantially in a transverse direction with respect to the length of the strip element. A first layer (31) of the strip element is of an easily adjusting material and a second layer (34) of the strip element is of a stiffer material in the loading direction than the first layer. In this way the loading of the strip element in the holder can be selected so that the strip element or its edge does not substantially bend in the direction of the movement of the facing surface. The invention also relates to an improved suction roll for a material web machine for improving the duration of the suction roll. A strip element is against a facing surface inside a perforated (7) mantel of the suction roll when a loading means (5) loads the strip element in a holder. In particular, in order to reduce the effects of the abrasion of the strip element, optionally: an inner surface of the mantel is surface treated by means of grain blasting, a thermal injection coating, a chemical or electro¬ chemical precipitation coating and/or a polymer-based coating; and/or a lubricant or additive is fed between surfaces abrading against each other; and/or at least part of suction holes in a wall of the mantel are broached (71 ) at the side of the facing surface inside the mantel. In addition, the invention relates to an arrangement for improving the duration of a suction roll. A strip element is against a facing surface inside a perforated mantel of the suction roll when a loading means loads it in a holder against the facing surface. In particular, the loading pressure of the strip element has been adjusted to a limit pressure at which a sufficient sealing effect is still maintained or harmful leakage does not occur. Moreover, the invention relates to a method for improving the duration of a suction roll when a strip element is loaded in a holder of the strip element against an inner surface of a perforated mantel of the suction roll. In particular, in order to reduce the effect of the abrasion between the strip element and its facing surface, loading pressure is adjusted to a limit pressure at which a sufficient
