Apparatus and method for producing absorbent structures with absorbent layers with channel(s) without absorbent material, using a first moving endless surface with specific raised strip(s) and a second moving endless surface with specific mating strip(s).

A method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, requires the application of a sacrificial material onto a base substrate in a predetermined pattern which is to be imparted onto products manufactured with the belt. The sacrificial material is deposited in droplets in a controlled manner so as to control the x, y, z dimension of the material deposited and preferably has having an average diameter of 10μ (10 microns) or more. A polymeric resin material is then deposited on the base substrate in all areas except those on which the sacrificial material has previously been applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

This invention relates to providing a system for improved web page generation and display. More particularly this invention relates to providing a system for dynamically creating web pages on demand, which are can be indexed by Internet-based search engine indexing programs, from contents stored in one or more databases. Further, index rankings created from the dynamically created pages are optimized using random, but contextually appropriate text replacement, within the web page URL link references and web-page content, and source code ordering.

A method of making resistors includes providing a sacrificial layer. Conductive material is then formed over a region of the sacrificial layer. Resistive material is then deposited over the first surface of the sacrificial layer such that the resistive material covers the sacrificial layer and the conductive material. A portion of the sacrificial layer is then removed to expose the conductive material. A method of making resistors includes the steps of providing a sacrificial layer, removing at least a portion of the sacrificial layer from regions of the sacrificial layer so as to create a plurality of cavities within the sacrificial layer, plating said cavities with a conductive material, disposing resistive material over the first surface of the sacrificial layer such that resistive material covers the sacrificial layer and said conductive material, and removing at least a portion of said sacrificial layer to expose the conductive material. In another embodiment, a method of making resistors includes the steps of providing a sacrificial layer having a roughened first surface and a second surface, depositing resistive material over the first surface of the sacrificial layer such that the resistive material covers the first surface of the sacrificial layer, and selectively etching the sacrificial layer to form electrodes.

A method for the production of a fabric for industrial use comprising extruding polymer material onto a carrier structure to produce a patterned design on the carrier structure, wherein a cross-sectional profile of the extruded polymer material is substantially convex. An apparatus for carrying out the method comprising a polymer extrusion apparatus structured and arranged to move in three mutually perpendicular directions. A fabric comprising a carrier structure and a patterned design comprising extruded polymer material arranged on the carrier structure, wherein the extruded polymer material is arranged to form a substantially convex cross section on the carrier structure. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The present invention is directed generally to fabrics, and more specifically to fabrics and belts employed in industrial processes.

An improved method of controlling build-up of adhesive coating on a Yankee drying cylinder preferably includes intermittently: (a) increasing the add-on rate of resinous adhesive to the drying cylinder substantially above the steady-state add-on rate; (b) segregating the absorbent sheet product produced while the add-on rate of resinous adhesive to the drying cylinder is elevated above the steady-state add-on rate from absorbent sheet product accumulated during steady-state operation; and (c) while the add-on rate of resinous adhesive to the drying cylinder is increased above the steady-state add-on rate, stripping at least a portion of the adhesive coating from the drying cylinder with a cleaning doctor.

A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics. The structure is a bicomponent extruded elastomeric netting or mesh having a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.

A papermaking belt including zones of material laid down successively using a 3D printing process. The zones include at least a pocket zone configured to form three dimensional structures in a paper web by applying vacuum to pull the paper web against the pocket zone. In at least one exemplary embodiment, the zone also include at least one vacuum breaking zone configured to limit an amount of paper fibers pulled through the pocket zone by the applied vacuum.

In a method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, a polymeric resin material is applied onto the surface of a base substrate in a precise predetermined pattern which is to be imparted onto products manufactured with the belt. The polymeric resin material is deposited in droplets having an average diameter of 10μ (10 microns) or more. The polymeric resin material is then set by means appropriate to its composition, and, optionally, may be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

A method of forming a structured web including the steps of providing a fiber slurry through a headbox to a nip formed by a structured fabric and a forming fabric and collecting fibers from the fiber slurry in at least one valley of the structured fabric.

A multi-ply absorbent towel made from papermaking fiber comprising at least a first ply and a second ply bonded together, the towel having a basis weight of greater than 30 lbs per 3000 ft² ream (48.8 gsm) and less than 50 lbs per 3000 ft² ream (81.4 gsm), wherein the plies are selected and adhered together such that the towel typically exhibits (i) a GM TEA, mm-g/mm² of greater than [0.00125 (GM Tensile, g/3″)−0.75] and (ii) a GM Tensile Modulus, g/in/%, less than [0.0083 (GM Tensile Strength, g/3″)+15.4] {(i) a GM TEA, mm g/mm², of greater than [0.00952 (GM Tensile, g/cm)−0.75] and (ii) a GM Tensile Modulus, g/cm/%, less than [0.0249 (GM Tensile Strength, g/cm)+6.06}.

Paper machine clothing method including covering an extended working surface with successive layers of a resultant material. Treating each successive layer with an energy source in accordance with predetermined instructions before adding a next successive layer to build up a three-dimensional fabric structure.
