ABSTRACT:
Diapers are made with substantial reduction of waste using a composite web of diaper main body material having a liquid impervious outer layer, a liquid pervious inner layer and an absorbent intermediate layer there between. The composite web has an indeterminate longitudinal extent substantially intact and uncut with parallel lateral side edge margins for substantially the entire web length. An independent web of diaper tab material is cut into discrete tab sections of predetermined mating shapes with substantially no unused waste material. The tab sections are affixed to the opposite edge margins of, and at regular longitudinal spacings along, the composite web. The composite web is cut transversely at regular longitudinal intervals there along corresponding to the spacings of the tab sections to produce discrete diapers each having a generally rectangular main body and four tabs at the respective corners of the main body.
