Abstract
An apparatus and method for successively forming disposable diapers wherein the diaper includes a fluidpermeable top cover layer, a moisture-absorbent core under the top cover layer and including a pad of fibrous material and sheets of cellulosic material on each side of the pad, and a fluid-impervious bottom cover layer under the interior core and secured to the top cover layer along longitudinal and transverse edges thereon. The apparatus and method include mechanisms for and steps of, as follows. Supplying and positioning an elongate moisture-absorbent core including a pad of fibrous material of less width than the width of the core and sheets of cellulosic material on each side of the pad. Embossing and securing the sheets of cellulosic material together along longitudinally-extending areas on each side of the pad for forming an envelope of the sheets of cellulosic sheets around the pad. Supplying and positioning an elongate fluid-permeable top cover layer on the top of the core and an elongate fluid-impervious bottom cover layer under the core. Feeding the superimposed top cover layer, interior core and bottom cover layer along a predetermined longitudinal path of travel. Applying a plurality of short, spaced-apart, generally longitudinally-extending, adhesive strips between the top cover layer and the bottom cover layer transversely across the superimposed top cover layer and bottom cover layer at longitudinally-spaced intervals for transversely securing the top cover layer and the bottom cover layer together at longitudinally-spaced intervals to form successively interconnected diapers. Securing the top cover layer and the bottom cover layer together along longitudinal side edges of the successively interconnected diaper. Transversely severing the successively interconnected diapers generally medially of the plurality of the longitudinally-extending adhesive strips to form individual diapers.
