Abstract:
A web construction of linerless reclosable diaper fastener stock made up of initially flat but flexible layers 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 to make diaper fasteners, and fabricatable completely by web coating, slitting and web-to-web laminating operations and without the necessity for folding operations and usable for high-speed dispensing on automatic equipment, said stock having a stock length extending in the machine direction and a stock width extending transversely to the machine direction, said stock including a first substrate bearing first substrate adhesive on its underside, and one or more additional substrates bearing one or more corresponding substrate adhesives, said stock width being of sufficient size to form by slitting a plurality of said diaper fasteners having fastener lengths aligned transversely to the machine direction, each fastener extending along first and second fastener length portions, said diaper fastener being mountable around the edge of a diaper with said first substrate constituting an anchoring substrate and said second fastener length portions of said one or more additional substrates comprising deployment means separable from said second length portion of said anchoring substrate for deployment and engagement with another part of the diaper, and end-tab means associated with a free end of said deployment means, a plurality of continuous lines or zones of adhesive-inhibiting masking extending in the machine direction along said substrate adhesive associated with at least one of said at least one or more additional substrates, said lines or zones extending across said second fastener length portions to define said end-tab means on the substrate adhesive associated with said at least one substrate.
