    摘要: The present invention discloses a method for laminating a gas permeable layer onto a preformed substrate by forming a laminate precursor comprising a substrate and a gas permeable layer in which a layer of adhesive is positioned between the gas permeable layer and the substrate surface. A layer of water is formed on the surface of the gas permeable layer and the wetted surface is contacted by a preheated platen and super heated steam is ejected onto the gas permeable layer causing the adhesive to cure and bond the gas permeable layer to the substrate.

    摘要: A process of making a liquid absorbing laminated structure comprising long lengths of absorptive tissues and an intermediate layer of absorptive particles is performed while the tissues are traveling in the direction of their lengths. A film of moistening liquid is transferred to a surface of a first tissue which is then supported in substantially horizontal position and showered with dry absorbent particles, which are rendered adhesive by absorption of the moistening liquid. A second tissue is superposed and the assembly is bonded together by passing it through the nip between a heated roller having a surface temperature of at least 110.degree. C. and a pressure roller. These rollers are pressed together at the nip by a pressure of at least 350 pounds per square inch and each has a surface hardness in excess of 90 Shore A Durometer.
