  • Patent number: 5902669
    Abstract: Disposable paper products, such as paper toweling, are provided with an indicator means which is disposed on said disposable paper product in a discontinuous or combination discontinuous/continuous pattern. The indicator means gives a visually recognizable signal to a user that desirable properties of the disposable paper product are maintained, even after the disposable paper product has become wetted with a substantially transparent aqueous liquid. The wet gray scale difference for the disposable paper product of the present invention is at least about 64 gray scale units when the disposable paper product is wetted with a substantially transparent aqueous liquid.

  • Patent number: 5874157
    Abstract: An embossed paper laminate having two laminae is provided. The laminae are joined such that there is at least one zone of the laminate wherein the peel strength of the laminate in that zone is greater than the peel strength of the laminate in other zones of the laminated paper product. The laminate is made by two close tolerance pattern rolls juxtaposed to form a nip. Each pattern roll has radially extending protuberances which contact the periphery of the other pattern roll intermediate its protuberances. The laminae are fed through the nip in face-to-face relationship and are embossed and adhesively joined to the other lamina by the radially extending protuberances. The laminating adhesive is supplied to the various zones of the laminated paper product at a level that is appropriate for providing the requisite peel strength for that zone.
