  • Patent number: 6652499
    Abstract: Absorbent product such as an incontinence pad, sanitary pad, diaper, absorbent inlay or the like, having a central absorbent portion with an upper permeable surface. The absorbent product also has a fluid-impermeable backsheet. In order to provide width adaptation and to allow a basin-shape to be formed in the product, two lateral portions are provided. Each of the lateral portions extends in the longitudinal direction of the product. The inner edge of each lateral portion is attached to the central portion by means of a surplus of material and the outer edge is a free outer edge. The lateral portions can thus move in a lateral direction independently of a central portion.
