Abstract
A disposable liquid-absorbing article, such as a diaper (10), sanitary towel or similar, having a substantially longitudinal shape and including an absorption body (12) and a cover (11) enclosing the absorption body with a liquid-pervious inner sheet (17) and an outer sheet (18) and contracting elastics members (23) in contact with at least one of the sheets to give the article its shape in an in-use position. The cover sheet on which the elastics members are applied, is connected to the inside and outside of the absorption body respectively, and the elastics members (23) extend with at least one substantially continually curved portion (24, 25) over at least an area of the absorption body. The strive of the elastics members to contract and the contact of the elastics members with one of the sheets, exert a tension force on the sheet in a direction towards the curvature center of the elastics members, whereby this force is transferred and absorbed by the absorption body.
