Abstract
A diaper tab stock of only two substrates provides diaper tabs that are linerless, that are refastenable, and that are of the relatively strong Y-configuration type. When tabs made from the stock are closed and reopened in the normal manner of use, part of one adhesive layer is 'extractively transferred' from between the two substrate layers to another part of the diaper to thereby present a 'fresh' adhesive face for subsequent refastening, such transfer occurring in the absence of any transfer of a substrate. The two-substrate construction may be formed by folding an appropriately coated originally single layer of substrate material.
