Abstract

DC60 (17/02/43) Various fiber sheets can be embossed and layered using irregular bonding patterns via a rivet-to-rivet embossing process. Different patterns are prepared on each fiber sheet, and the sheets are connected in the bonding clamps to create layered sheets. The bonding patterns created in the bonding clamps have an irregular appearance. This irregularity of the bonding pattern reduces vibrations within the machinery and allows for increased machine speeds. The irregularity of the pattern can be determined using self-similarity counting or energy inhibition methods.

Claims (23)

1. A method for embossing and layering cellulose fiber sheets with reduced vibration and increased speed. This method consists of the following steps: - Passing the first fiber sheet along the first embossing roller to create the first pattern by protruding sections. - Passing the second fiber sheet along the second embossing roller to create the second pattern by protruding sections. The first and second patterns differ in their distribution across the fiber sheets. - Connecting the first and second fiber sheets to create a layered sheet in such a way that the protruding sections of the first sheet adhere to the protruding sections of the second sheet at the layer interface, creating a bonding pattern. The area of adhesion between the first and second protruding sections serves as the bonding area. This amounts to between approximately 1% and 60% of the total area of the stacked sheet, and the welding wire has a disordered distribution within the interface area of the stacked sheets. 2. Method of Claim 1, where the weld pattern is irregular in nature, and the weld pattern has a self-similar count of 1. 3. Method of Claim 1, where the welding pattern is irregular in nature, and the welding pattern has an energy inhibition factor between approximately 8 and 25. 4. Method of claim 2, where the area to be joined shall be between approximately 3% and 24% of the total area of the stacked sheet. 5. Method of Claim 2 whereby the procedure for joining the first and second strands is incorporated by applying an adhesive to at least one of the protruding parts of the strands. 6. The method of claim 1, which will subsequently be incorporated with a third fiber placed between the first and second fibers before connecting the first and second fibers together. 7. Method of claim 2, where the first and second fiber sheets move at speeds between approximately 500 and 8000 feet per minute. 8. A method for embedding and layering two cellulose fiber sheets with reduced vibration and increased speed, consisting of the following steps: - Embossing the first cellulose fiber sheet between the first embedding roller and the first corresponding roller to create the first pattern of protrusions extending outwards from the sheet surface. - Embossing the second cellulose fiber sheet between the second embedding roller and the second corresponding roller to create the second pattern of protrusions extending outwards from the sheet surface, with the first and second patterns differing in their distribution on the sheets. - Applying an adhesive to at least one of the protrusions. - Passing the first and second sheets between the first and second embedding rollers, where the first pattern of protrusions adheres to the second pattern of protrusions at the interface to create a bonding pattern, with the contact area between the first and second protrusions. The second set of protruding sections will be the bonding areas, where the bonding area will be between approximately 1% and 60% of the total area of the integrated fiber sheet, and the bonding pattern will be irregularly distributed within the interface of the overlapping layers. 9. Method of Claim 8, where the weld pattern is irregular in nature, where the weld pattern has a self-likeness count of 1. 10. The method of claim 8, where the welding pattern is irregular in nature, has an energy inhibition factor between approximately 8 and 25. 11. Method of claim 9 where the area to be joined shall be between approximately 3% and 24% of the total area of the stacked sheet. 12. The method of claim 9, whereby the subsequent steps of passing the first and second fiber plates between the first and second embossing rollers are combined with the passing of a third fiber plate between the aforementioned first and second fiber plates. 13. The method of claim 9, where the first and second fiber plates move at speeds between approximately 500 and 8000 feet per minute. 14. Method of claim number 9, whereby the corresponding roller, one of which has a rubber surface. 15. Method of claim 9, where the first and second embossing rollers have equal diameters. 16. Method of claim 9 where the first and second embossing rollers have different diameters. 17. A multi-layered fiber sheet made of cellulose material with an irregular interlocking pattern. This multi-layered fiber sheet is produced by a process consisting of: - Passing the first fiber sheet along the first embossing roller to create the first pattern on the first fiber sheet; - Passing the second fiber sheet along the second embossing roller to create the first pattern on the second fiber sheet, where the first and second patterns differ in their distribution across the fiber sheet; and - Joining the first and second fiber sheets to create an overlay such that the protrusions of the first fiber sheet adhere to the protrusions of the second fiber sheet at the overlay interface, creating an interlocking pattern. The area of adhesion between the protrusions of the first and second fiber sheets serves as the bonding area, with the bonding area ranging from approximately 1% to 60% of the total area of the overlay. 18. Method of Claim 17 where the weld pattern is irregular in nature, where the weld pattern has a self-likeness count of 1. 19. Method of Claim 17 where the welding pattern is irregular in nature, and the welding pattern has an energy inhibition factor between approximately 8 and 25. 20. A multi-layered fibrous sheet made of cellulose material consists of: - A primary fibrous sheet with protrusions forming the first pattern. - A second fibrous sheet with protrusions forming the second pattern. The primary and second patterns are distinct. The protrusions of the primary fibrous sheet are attached to the protrusions of the second fibrous sheet at the layer interface to create a bonding pattern. The bonding area between the primary and secondary protrusions is the bonding area. The bonding pattern is irregularly distributed within the layer interface. 21. The weld sheet of claim 20, where the weld pattern is irregular in nature and has a self-likeness count of 1. 22. The weld pattern of claim 20, where the weld pattern is irregular and the weld pattern has an energy inhibition factor between approximately 8 and 25. 23. The bonding area of claim 20 shall be between approximately 3% and 24% of the total area of the bonded sheet.
