A multilayer belt structure that can be used for creping or structuring a cellulosic web in a tissue making process. The multilayer belt structure allows for the formation of various shaped and sized openings in the top surface of the belt, while still providing a structure having the strength, durability, and flexibility required for tissue making processes.

A security document has a security substrate, a security device and a structural weakness element, wherein the security device is coupled to the security substrate, wherein the structural weakness element is integrated with at least one of the security substrate or the security device, the structural weakness element defining an anti-harvesting area and a bulk area, and wherein the anti-harvesting area has one or more of structural fidelity or optical fidelity with the bulk area.

Security document with attached security device which demonstrates increased harvesting resistance

A watermark sheet made up of a substrate layer with opposing water and fiber surfaces, a pattern of at least two watermark indicia, and a set of apertures extending from the water surface toward the fiber surface of the substrate layer, is provided. The pattern of at least two watermark indicia is distributed over a continuous area of the fiber surface. The inventive watermark sheet provides watermarks of improved quality. Also provided is a watermark sleeve made up of a cylinder mold and the inventive watermark sheet wrapped around and affixed to an outer diametric surface of the cylinder mold. In addition, methods of manufacturing the watermark sheet, the watermark sleeve, a watermarked paper and a high security document are provided, as well as products resulting from these methods of manufacture.

Watermark sheet, apparatus, and document, and methods for providing the same

A sheet material having a security device applied over a paper machine made or 'soft-edged' through-hole and a method for preparing such a sheet material is provided. The through-hole(s) is formed in a forming fibrous web before it becomes sufficiently consolidated and then the security device is applied onto the fibrous web and preferably over the through-hole(s) at or near a couch roll or similar tool of a paper machine when the fibrous web constitutes a sufficiently consolidated, fully formed wet web. Moreover, papers made in accordance with the inventive method, when subjected to the Circulation Simulation Test, showed minimal damage at the paper/security device interface. Further, the surface-applied security devices showed acceptable levels of intaglio ink adhesion, and the papers had higher cross-direction (CD) tensile strength and much less show-through on opposing sides thereof.

The invention relates to a security sheet or document having enhanced watermark(s). In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects synthetic image(s) that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.

Security sheet or document having one or more enhanced watermarks

A method for applying a security device (e.g., a micro-optic security thread) to a fibrous web during manufacture is provided. By way of the inventive method, the security device is preferably applied onto the fibrous web at or near a couch roll or similar tool of a paper machine when the fibrous web constitutes a sufficiently consolidated, fully formed wet web. Papers made in accordance with the inventive method, when subjected to the Circulation Simulation Test, showed minimal damage at the paper/security device interface. Moreover, the surface-applied security devices showed acceptable levels of intaglio ink adhesion, and the papers had higher cross-direction (CD) tensile strength and much less show-through on opposing sides thereof.

The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission. As will be readily appreciated, the inventive security sheet or document offers greatly improved counterfeit-resistance.

A papermaking fabric having a top layer and a bottom layer of interwoven machine direction (MD) yarns and cross-machine direction (CD) yarns bound together with warp binder yarns. At least some of the CD yarns are made of a material which generates a strong contractive force when returned to room temperature after heat-setting (annealing under MD tension). These CD yarns are positioned such that the strong contractive force offsets tension forces generated when the fabric is placed under load and which typically result in an edge curl. An exemplary material for these CD yarns is polybutylene terephthalate (PBT).
