At least one embodiment generally relates to using an installation tool (200) to pass an expansion mandrel (202) through an elongated member (302) to at least locally, radially expand at least a portion of the elongated member and achieve an interference fit with a radially expandable member (304) located about an outer surface of the elongated member. In one embodiment, the elongated member is radially expanded over its entire length and may include a stepped feature (309) so that only a portion of the elongated member (302) achieves the interference fit with the radially expandable member (304). During the radial- expansion process, both the radially expandable member and the elongated member may be at the same or approximately the same temperature. Before the radial-expansion process, the radially expandable member may be assembled using clearance fitting techniques.
L'invention concerne un revêtement externe étirable destiné à une utilisation avec un article absorbant, ledit revêtement comprenant un film élastomérique. Le film élastomérique comprend au moins une couche superficielle qui est moins collante qu'au moins une couche centrale. Le revêtement extérieur peut comporter une couche non tissée comprenant différentes combinaisons structurales de fibres filées-liées, de fibres de fusion-soufflage et/ou de nanofibres. La combinaison de composants plastiques et élastiques résulte en un revêtement extérieur présentant des propriétés mécaniques, physiques et esthétiques favorables. Le revêtement extérieur peut être rendu étirable uniaxialement ou biaxialement par un procédé d'activation mécanique.
