    摘要： A method for forming an apertured web which may be used as a topsheet on a disposable absorbent article, such as a diaper. The web (240) is fed in as machine direction through a first nip (250) formed by a pair of rollers one of the rollers having a smooth outer surface and the other roller having an outer surface with a plurality of projections extending from it's outer surface. At least one of the rollers of the first nip (250) is heated. The first nip (250) apertures the web with a plurality of apertures each having a fused perimeter. The web (240) is then cooled to solidify the fused perimeter of the apertures. The web (240) is then fed through a second nip (280) formed by a pair of rollers to break the solidified fused perimeter of the apertures. One of the rollers of the second nip (280) has an outer surface with a plurality of grooves.

    摘要： The present invention relates to superabsorbent polymer particles having functionalizers covalently bound to the surface of precursor superabsorbent polymer particles. The functionalizers of the present invention comprise a grafting unit with a radiation activatable group and a functional unit covalently bound to the grafting unit. The grafting unit is bound to an aliphatic C—H group comprised at the surface of the precursor superabsorbent polymer particle. The functional unit comprises chemical structures which are not present in the precursor superabsorbent polymer particle. These functional units add an additional function to the precursor suberabsorbent polymer particle or modifying an existing function of the precursor superabsorbent polymer particle. Moreover, the invention relates to a process for making these superabsorbent polymer particles.

    摘要： A bag of folded disposable diapers including folded diapers arranged in at least two superimposed stacks in a direction substantially parallel to their thickness. Each of the diapers has a pair of substantially planar surfaces which are oriented to be substantially parallel to the side panels of the bag and each diaper is folded along at least one folding line in the cross direction so as to define at least one folded area and two non-folded end areas. The diapers are arranged in the bag such that the non-folded end areas corresponding to the waist areas are positioned inwardly, away from the end panels of the flexible bag.

    摘要： The invention is a tubular two-chamber liquid metering device for leaktlight insertion into a container opening. The metering device consists of a cylindrical wall with a closed base and a cover which is provided with a passage for a pouring duct. The wall has at least one opening in the region of the cover and at least one further opening is located on a peripheral line between the opening and the base. Disposed in the outer cylindrical chamber defined by the wall, the base and the cover is a tubular body which at one end is connected in a leaktight manner to the pouring duct and at its other end maintains a distance from the base. The tubular body has at least one opening on a peripheral line in the region of the connection to the pouring duct. A freely movable body with a circular cross-section is provided in the main metering chamber defined by the inner cylinder between the opening and the base. The invention further provides a method of metering liquids via a chamber device in which a free body is provided in the metering chamber in order to close a pouring duct. The volume of the free body is such that the free volume remaining in the metering chamber corresponds to the amount of liquid to be metered.
