  • Patent number: 4743242
    Abstract: The invention relates to a system for fastening refastenable garment such as diaper or incontinent garment in which a tape and polymer backing material for the garment are provided such that tape may be removed after refastening to the diaper without tearing of the polymer material. The system of the invention utilizes a polypropylene tape material that is embossed on the outer surface and smooth on the adhesive-carrying surface. The adhesive on the tape is a semihard adhesive that provides high adhesion values to the polymer that nevertheless may be peeled free for removal of the tape and subsequent refastening. The polymer forming the outer backing if the diaper is a relatively thick, embossed polymer sheet. In the refastenable system of the invention the strength and adherence of the tape to the strong, embossed polymer backing sheet is controlled so as to achieve secure fastening with release of the adhesive from the embossed sheet without tearing.

  • Patent number: 4726876
    Abstract: Apparatus for changing the spacing between articles of a moving array of discrete articles includes transfer means mounted for orbiting along a closed orbital path passing through a receiving zone and a discharge zone. The orbital radius of the transfer means is adjustable to provide an orbital radius in the discharge zone which is different from that in the receiving zone. The transfer means are maintained in fixed, equal angular distances between them along the orbital path whereby the orbital path distance between adjacent transfer means is different in the discharge zone from that in the receiving zone thereby resulting in a different spacing between adjacent articles in the discharge zone from that in the receiving zone. Two or more orbital spacer means may be utilized in tandem to provide the change in spacing in stages.

  • Patent number: 4726873
    Abstract: This invention is generally accomplished by providing continuous self-adhesive strands of elastic to a substrate having retractable supports extending therefrom. The retractable supports in a convex pattern are contracted with the self-adhering elastic and the substrate bearing the elastic and supports is brought into contact with the web to which the elastic is to be transferred. The series of supports around which the elastic contacts are forced to retract as the self-adhering elastic is pressed against the web causing the elastic to transfer to the substrate thereby creating an elastic band on the substrate. In a preferred form the substrate is fed two strips of self-adhering elastic that are applied on each side of a series of a convex pattern of pins and then pressed together around opposing sides of the convex pattern of pins to seal the elastic to itself and sever the elastic, creating a contoured closed loop around the pins.

  • Patent number: 4725473
    Abstract: The cloth-like, liquid impervious composite material is made by applying a nonwoven layer of loose, unadhered fibers to a liquid impervious film, and then point-bonding the nonwoven layer to the liquid impervious film to form discrete points of adhesion between the fibers and film. Because the fibers in the nonwoven layer are loose and unadhered when applied to the film, the resulting composite material has improved loft and softness. Also, when the composite material is elasticized by an elastic material, it gathers into a more pleasing appearance.

  • Patent number: 4724114
    Abstract: The invention generally provides for formation of meltblown material containing wood fiber on to a continuous foraminous belt. During formation a polymer and wood fiber first layer is applied to a moving belt from at least one bank of meltblown forming apparatus. This first layer does not contain superabsorbent. The belt carrying the first layer passes beneath at least one further source of meltblown fiber into which superabsorbent is added along with the wood fibers. This provides at least one additional layer integrally connected to the first-formed layer and having superabsorbent properties. The first layer acts to aid in trapping of any superabsorbent which is not immediately entangled in the meltblown and wood fibers and prevents it passing through the forming belt.
