Abstract

DC60 (27/01/42) A thin-layered fibrous structure or laminate consisting of at least two sheets of fibrous material, and methods for producing such a structure are presented in this invention. At least one sheet of fibrous material, and preferably two, may be embossed. The sheets of fibrous material are joined together in a face-to-face, relative-moving manner to create a laminate structure in which the sheets of fibrous material can move relative to each other during consumer use without causing tearing or separation of any of the individual sheets of the laminate structure. The sheets of fibrous material making up the laminate structure may be joined relative to each other by adhesives, by mechanical splicing of erected fibers created on the surface of the fiber sheets, or by a combination of adhesives and splicing of erected fibers. A thin-layered fibrous structure or laminate consisting of at least two sheets, and methods for producing such a structure are presented in this invention. At least one sheet of fibrous material, and preferably two, may be embossed. The sheets of fibrous material are joined together in a face-to-face, relative-moving manner. These materials can move and interact with each other to create a laminate structure in such a way that the fiber sheets can move and interact with each other during use by the consumer, without causing tearing or separation of any single fiber sheet that makes up the laminate structure. The fiber sheets that make up the laminate structure can be joined movably using adhesives, by mechanical splicing of vertical fibers created on the surface of the fiber sheets, or by a combination of adhesives and mechanical splicing.

Claims (18)

1. A fibrous structure made into thin layers or laminates consisting of at least a primary and a secondary fibrous sheet. These sheets are bonded face-to-face in such a way that at least a portion of the primary sheet can move relative to its corresponding portion in the secondary sheet without tearing either the primary or secondary sheet. 2. Laminated structure as per claim 1, where the fiber sheet, the first material, is embossed. 3. Laminated structure as per claim 2, where the fiber sheet, the second sheet material, is embossed. 4. Laminate structure according to claim 3 where the first and second fiber sheets are bonded together in a butt-lock pattern. 5. Laminate structure as per claim 3, where the first and second fiber sheets are bonded together in a mesh pattern. 6. Laminate structure as per claim 3 where the first and second fiber sheets are bonded together in a two-layer thin laminate arrangement. 7. The laminate structure under claim 2, which is further comprised of bonding material that connects the first and second fiber sheets together in a movable manner. 8. Laminate structure as per claim 1, whereby the fiber sheet, first and second sheet of material, are able to move laterally relative to each other. 9. The laminate structure under claim 1 where the first sheet of material has vertical fibers facing the second sheet of material. 10. Laminate structure as per claim 9, where the second fiber sheet has its fibers facing upwards toward the first fiber sheet. 11. The laminate structure under claim 10, where the aforementioned erected fibers of the first fiber sheet are mechanically bonded to the aforementioned erected fibers of the second fiber sheet in order to connect the first fiber sheet to the second fiber sheet in a movable manner to form the said laminate structure. 12. Laminate structure as per claim 11, whereby the established fibers of at least one of the first and second said fiber sheets are fused together with at least one of the first and second said fiber sheets. 13. Laminate structure as per claim 11, whereby the established fibers of at least one of the first and second fiber sheets are spaced to at least one of the first and second fiber sheets. 14. The manufacturing process of laminated fiber structures consists of steps for arranging at least a first and a second fiber sheet, and steps for connecting the first and second fiber sheets together in a face-to-face manner, ensuring that at least part of the first fiber sheet can move relative to the corresponding part of the second fiber sheet without tearing the first and second fiber sheets. 15. The procedure under Claim 14, which includes the step of embossing at least one of the first and second fiberboard sheets to create an embossed pattern. 16. The procedure under Claim 15, which includes additional steps for providing the adhesive material and steps for making such adhesive material adhere to at least one of the first and second fiber sheets. 17. The procedure under claim 16, whereby the said adhesive material is applied to the said embossed pattern. 18. The process under claim 15, which includes a step to create a raised fiber portion on at least one of the first and second fiber sheets, and a step to arrange at least the first and second fiber sheets to face each other so that the raised fibers on the first sheet are in contact with the fibers on the second sheet, in order to create the said laminate fiber structure (Clause 18, page 2, figure 6).
