  • Patent number: 7931635
    Abstract: Oversized adult diapers are made on converting machinery designed for handling only components no greater than a maximum component width, while utilizing as an outer layer component of the diapers an elongate sheet-like web having a width exceeding the maximum component width of the machinery. The web is pre-formed with at least one folded pleat along a laterally outward margin of the web, such that the pleat reduces the width of the web to less than the maximum component width. The pleat is temporarily tacked to retain the pleat against unfolding while the web is handled by the machinery, but is yieldable to unfold when a diaper made with the web is donned for wearing. The pre-formed pleated web is delivered to the machinery, which is then operated in normal manner to incorporate the web into a plurality of diapers.

  • Patent number: 7842021
    Abstract: Absorbent articles with waist seals are disclosed. The seals are formed from folded stacks, discrete segments, or pleated material arranged to provide a resiliently compressible seal that can be located at one or more locations within the absorbent article, e.g., along a central portion of the rear waist region of a diaper. The seals may be constructed from relatively thin materials that (through folding, stacking, pleating, etc.) can provide a resiliently compressible seal that is thick enough and appropriately shaped to conform to the wearer's anatomy well enough to provide the desired sealing. At the same, time, the continuous web material used to form the seal is preferably thin enough to be economically delivered to the manufacturing line in roll form. The seals may be provided in the form of compressed seals that expand when one or more openings are formed in a sealed cavity containing compressed resilient material.
