A disposable diaper having improved fit about the legs and/or waist of the wearer and having reinforced corners for enhanced securement of the diaper about the wearer is disclosed. Improved fit and reinforcement are obtained by an elongated, inherently elastic ribbon member positioned along at least one margin of the diaper. The ribbon member is secured to the diaper so as to provide an elastic region at a central portion of the margin and a unitary, relatively inelastic reinforced region in a corner portion of the diaper.

Method of forming a conformable garment with 'killed' elastic portions

A laminated structure, such as a disposable diaper is provided which includes elastic in the margin to provide gasketing about the legs and, if desired, an improved fit about the waist. A method is provided for placing elastic only in the areas to be gathered and removing the unused elastic. In the method stretched elastic is intermittently adhered to a web substrate along a longitudinal line at the terminating portion of the gasketed area. The elastic is then severed adjacent the adhered portions and the unused elastic is removed.

Laminated structures having gathered and ungathered marginal portions

Method and apparatus for continuously attaching an elastic member to discrete portions of a moving web to impart an elasticized character to predetermined portions of the web while preserving the inelastic character of the other portions of the web.

A laminated structure having a marginal area with gathered and ungathered portions which provide an improved fit about a portion of the human body, said laminated structure comprising an elastic member disposed between first and second substrates of flexible gatherable material, said elastic member comprising a plurality of longitudinally extending elastic elements with the elements transversely connected over a portion of their length to define apertures and an end portion of the member comprising only longitudinally extending elements and the first and second substrates of said laminated structure being secured together through at least some of said apertures.

Method of making laminated structures having gathered and ungathered

A laminated structure having a gathered marginal area which provides an improved fit about a portion of the human body, said laminated structure comprising an elastic member disposed between first and second substrates of flexible gatherable material, said elastic member comprising a plurality of interconnected longitudinally extending elastic elements defining apertures therebetween, the longitudinally extending elements having different cross-sectional areas to provide varying degrees of tension across the width of the marginal area and the first and second substrates of said laminated structure being secured together through at least some of said apertures.

Laminated structures having gathered marginal portions

A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant and a backing sheet defining a diaper outside surface is provided with adhesive tabs having a fixed end and a free end. The fixed end has an adhesive coating on one face thereof for permanently attaching the fixed end of the tab to a marginal portion of the diaper outside surface. The fixed end is divided lengthwise to define anchoring legs which are contiguous at a location spaced inwardly from the terminal edge of the fixed end and are diverging with respect to one another to a spaced-apart position at the terminal edge of the fixed end for facilitating in distributing stresses imposed on the tape segment. The free end has an adhesive coating on one face thereof, and release means is releasably attached to the adhesive coating on the free end of the tab. The free end is separable from the release means to make the free end available for use in securing the diaper about an infant.
