  • Patent number: 4936840
    Abstract: A method is disclosed for making a fastener landing zone within a selected area on the front waist panel of a diaper. The front waist panel and a rear waist panel are stretchable in a cross-body direction, the rear panel having elongated ears bearing mechanical fasteners on inner, body-facing surfaces thereof which are releasably engageable with mechanical fasteners provided on the landing zones. The landing zones are shaped, sized and oriented on the front waist panel so as to impart a tensile force distribution pattern thereacross, directing tensile stresses away from the leg and waist openings while providing a band of abdominal support across the front waist panel between the landing zones.

  • Patent number: 4923456
    Abstract: A disposable diaper comprises an absorbent structure integrated within an outer cover. The outer cover includes front and rear elasticized waist panels, an intermediate crotch panel separating the waist panels from one another, a pair of sides extending between and interconnecting the waist panels, a pair of leg openings delimited along the sides and front and rear pairs of ears delimited at the sides of the front and rear waist panels, respectively. The rear pair of ears define elongated shapes with internal, body-facing surfaces, a proximal portion spaced from a line centered on the longitudinal axis of the diaper, suer end portions spaced distally from the proximal portions and elastomeric medial portions adjustably spacing and separating the user portions from the proximal portions.

  • Patent number: 4786346
    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: 4767487
    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: 4758293
    Abstract: Apparatus and method for ultrasonically bonding a web utilizes ultrasonic bonders having respective anvil and sonotrode components which are synchronously orbited with each other and with the rotation of a rotatable drum which carries the web of material to be bonded. One of the anvil and sonotrode components is orbited exteriorly of the drum and the other interiorly of the drum and they are brought into facing alignment through openings in the drum to clamp segments of the material therebetween during passage through a bonding segment of the travel path of the web about the drum. The bonder component orbiting exteriorly of the drum is axially translated away from the anvil along the drum in order to provide clearance for withdrawal of the bonded material from the drum. In this manner, an ultrasonic bonder may clamp the material at a single location for a large segment of its travel along the rotation path of the drum, thereby attaining a bonding time not limited entirely by the travel speed of the web.

  • Patent number: 4739910
    Abstract: Apparatus and method are provided for inverting a child's training pant or the like. The apparatus generally comprises a pair of mutually facing, diverging conveyor belt assemblies and a pair of suction systems respectively associated with the conveyor belt assemblies. As the conveyor belt assemblies move the training pant therealong, the suction systems act on opposite surfaces of the training pant to draw them apart, thereby opening the training pant. At the end of the conveyor belt assemblies is an inverting assembly for inverting the opened pant.

  • 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.
