Single substrate tab fastener

A web construction of linerless diaper tab stock made up of a single flat but flexible coated substrate suitable to be formed in long passes along the machine direction of a coating and laminating line and to be rolled up for storage and shipment, and unrolled for use by diaper manufacturers, and fabricatable completely by web coating and slitting operations and without the necessity for laminating or folding operations, and suitable for high speed dispensing on automatic equipment, including a substrate extending, transversely to machine direction, along first, second, third, fourth and fifth endwise length portions, said first and third length portions including adhesive on the top side of the substrate and release means on the bottom side, said second length portion having no release means on the bottom side of the substrate to thereby define an anchoring portion where release means is absent, said fourth length portion being sufficiently wide for the bottom side of the substrate at the fourth length portion to be folded across said third length portion and reach and at least partially cross said anchoring portion, said fourth length portion having adhesive on the bottom side of the substrate and release means on the top of the substrate at at least the part of the fourth length portion which is capable of crossing said anchoring portion when said fourth length portion is so folded, said fifth length portion including adhesive and release means on opposite sides of the substrate.
