  • Publication number: 20240043178
    Abstract: A reclosable package and processes for making it are disclosed. The reclosable package includes a front panel, a back panel, an upper seal region adapted to be broken to allow a first opening of the reclosable package, a lower seal opposite the upper seal region, a vertical seal extending between the upper seal region and the lower seal on the back panel between the first side edge and the opposing second side edge; and a self-mating fastener disposed adjacent the upper seal region in an interior of the reclosable package. The self-mating fastener includes first and second fastener members each having fastener elements, an open configuration to allow access to the interior volume of the reclosable package, and a closed configuration in which the fastener elements of the first and second fastener members are engaged. In the closed configuration, the self-mating fastener is up to 800 micrometers thick.

  • Patent number: 9744755
    Abstract: A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.

  • Publication number: 20130143462
    Abstract: An assembled intermediate is described comprising a fluid transport element proximate an absorbent material. The fluid transport element comprises a thermoplastic nonwoven web comprising a plurality of coiled filaments having an average diameter of 200 to 500 microns interengaged by means of intermittent bonds. The web preferably has certain properties such as a thickness of 3 to 20 mm, a density ranging from 0.02 to 0.10, and a work of compression of no greater than 20 kJ/m3. Also described are articles comprising such assembled intermediate.

  • Patent number: 7052639
    Abstract: Tool rolls and methods of using the tool rolls to manufacture articles with one or more structured surfaces are disclosed. The tool rolls include an outer surface that, when used in connection with materials of the proper viscosity or formability, can form a structured surface on an article. Because the tools are manufactured in roll-form, they can be advantageously used in continuous manufacturing processes. Alternatively, discrete articles may be processed using the tool rolls. The tool rolls are constructed of a cylindrical base roll and are wrapped with one or more continuous wires in a helical pattern. The wires are used, in essence, to form a structured surface on the tool roll that is the negative of the structured surface to be formed on the articles processed using the tool roll. One of the wires wound around the base roll may include depressions formed therein that, when wound in helical coils about the base roll, form cavities on the outer surface of the tool roll.

Because the tools are manufactured in roll-form, they can be advantageously used in continuous manufacturing processes. Alternatively, discrete articles may be processed using the tool rolls. The tool rolls are constructed of a cylindrical base roll and are wrapped with one or more continuous wires in a modified undulating helical pattern. The modified helical pattern results in the distance between the first wire and a reference plane transverse to the longitudinal axis of the base roll sequentially increasing and decreasing at least once when moving in one direction about a circumference of the base roll.

  • Patent number: 6368097
    Abstract: A method and apparatus for capping a headed stem fasteners. The precursor web having a backing with a rear surface, a front surface, and a multiplicity of polymeric stems projecting distally from the front surface of the backing is fed into a variable nip between a heated member opposite a support surface. The support surface has a shape generally conforming to the contour of the heated member. The variable nip compressively engages the polymeric stems between the heated member and the support surface so that distal ends of the polymeric stems are deformed. The heated member can be a heated roll or a heated belt. The support surface may be a curved capping shoe or a belt shaped to create a particular nip profile.
