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.

Abstract: Diaper tab stock comprises a unitary substrate extending, transversely to machine direction, along first and second endward length portions separated by a third intermediate length portion, with adhesive on its topside at the first endward length portion, on its bottom side at the second endward length portion, and on neither side at the third intermediate length portion which separates the other two. A release coating on the bottom side of the first length portion extends partly onto the intermediate third length portion but stops short of the second length portion.In a preferred method of manufacture and use, a release coating on the top side of the second length portion serves as a releasing support both for the adhesive which ends up on the bottom side of the second length portion and then for the adhesive on the first length portion when the first length portion is folded onto the second length portion.

Abstract: A web construction of diaper tab stock is provided for separation into diaper tabs of the refastenable type wherein a minor part of the tab transfers from one part of the diaper to another incident to the first cycle of fastening and unfastening. The release-coated substrate face which substitutes for a liner does not stay with the main part of the tab structure during such cycle but instead transfers with the minor part of the tab structure. The diaper tab stock is suited to low cost production and to high speed dispensing on automatic equipment by diaper manufacturers.
