  • Patent number: 6916969
    Abstract: The invention relates to a material laminate for use as a covering sheet on absorbent articles such as sanitary napkins, incontinence protectors, diapers, pant diapers, or the like. The material laminate comprises a first, fluid pervious fibrous material layer and a second fluid pervious porous material layer, wherein at least one of the two material layers comprises thermoplastic material and wherein the two material layers are mutually connected by means of the covering material laminate exhibiting bond sites within which the thermoplastic material has been caused to at least partially soften or melt and thereby bond the two material layers together.

  • Patent number: 6602237
    Abstract: An absorbent product includes an absorbent portion with an absorbent body between a liquid permeable sheet and a liquid impermeable sheet, and flexible flaps projecting from tapering longitudinal edges of the absorbent portion. A first removable protective layer covers substantially the entire absorbent portion and second and third removable protective layers each cover substantially all of a respective one of the flexible flaps. Each of the second and third protective layers is directly opposite the first protective layer along substantially an entire length of a first line along the respective longitudinal edge of the absorbent portion. The second and third protective layers are at least partially separated from the first protective layer by a cut line that follows the respective first line.

  • Patent number: 6569138
    Abstract: An absorbent article includes an absorbent body enclosed between a liquid-permeable outer sheet and a liquid-impermeable outer sheet, a front part facing forwards when the article is worn, and a rear part. The absorbent body tapers rearwardly to the end of the rear part from a section of greatest width situated in said front part. The article includes flexible outwardly projecting flaps which extend on respective sides of the absorbent body and have outer edges that are inclined relative to the longitudinal symmetry axis at an angle such that the distance between the outer sides of said flaps and the axis decreases in a direction towards the rear end of the article. At least two adhesive strings are applied to at least one of the flaps on the side thereof which, in the unfolded state of the flap, lies on the same side of the article as the liquid-impermeable outer sheet.

  • Patent number: 6524422
    Abstract: A method of manufacturing absorbent articles (17) in the form of sanitary napkins, panty liners or incontinence protectors for women, includes the step of cutting a web (5) of protective layer material with a sequence of pairs of cuts (8, 9) which are so spaced apart so that when the web (5) of protective layer material is placed on a web (1, 3, 4) of article blanks the two cuts (8, 9) in each pair of cuts in the sequence of pairs of cuts will lie linearly between the points of connection of flaps (23, 24) with the longitudinal edges of each article. The thus cut web (5) of protective layer material is then placed on the web (1, 3, 4) of article blanks and individual articles (17) are cut from the composite web (1, 3, 4, 5) in a second cutting step that defines the periphery of the articles.

  • Patent number: 6452064
    Abstract: A method of manufacturing a fluid permeable covering sheet (9) for an absorbent article such as a diaper, a sanitary napkin, an incontinence protector or the like, wherein heated needles (4) are brought to penetrate a sheet of textile material (1) comprising at least one thermoplastic component, whereby the thermoplastic component closest to the needles (4) melts, whereafter the needles (4) are removed and the heated material (1) is passed through at least one nip of rollers (7) so that the thermoplastic component closest around the apertures is smoothed out into a substantially smooth material surface around the apertures, whereafter the thermoplastic component is brought to solidify. The invention further pertains to an apertured covering sheet (201, 301) for an absorbent article manufactured in accordance with the method, and an absorbent article (300) provided with a covering sheet manufactured in accordance with the method.

  • Publication number: 20020082579
    Abstract: In the continuous manufacture of absorbent articles (17) in the form of sanitary napkins, panty liners or incontinence protectors for women, the invention provides a method of providing said articles with protective layers (25, 26, 27). According to the invention, a web (5) of protective layer material whose width corresponds at least to the greatest width of the article (17) in the machine direction (M) is provided with a sequence of pairs of cuts (8, 9) which are so spaced apart that when the web (5) of protective layer material is placed on a web (1, 3, 4) of article blanks the two cuts (8, 9) in each pair of cuts in the sequence of pairs of cuts will lie linearly between the points of connection of the flap (23, 24) with the longitudinal edges of each article.
