A series of nips (200, 202, 204, 412, 414) formed by intermeshing grooves (22, 24, 26, 28) provides for a higher degree of stretch, particularly for lightweight webs (100) by stretching in stages in multiple grooved nips. The ability to adjust the degree of stretch at each nip can provide a high degree and variability of stretch with reduced web damage compared to a single step application of the same stretch. Improvements to the manufacture of lightweight components of personal care products such as diaper backing components are obtained.

A process and apparatus for embossing thermoplastic products having precise microstructured surfaces including using a continuous press having upper and lower belts with the embossing pattern(s); feeding thermoplastic material through the press where heat and pressure are applied to form the embossed pressure microstructure, and cooling the embossed material, all while maintaining pressure. A continuous embossing tool is provided by welding segments together, the welds including interface material at the weld joint which is of a different material than the segment material to increase the tensile strength.

An apparatus for embossing a flexible substrate with an optically transparent compliant media is disclosed. The complaint media includes an optically transparent imprint stamp with an imprint pattern therein. The flexible substrate is coated with a photopolymer material. The compliant media can be connected with an optically transparent belt material to form an embossing belt or connected with an optically transparent cylinder to from an embossing drum. A coated side of the flexible substrate is urged into contact with the imprint stamp and the imprint pattern is embossed in the photopolymer material and an ultraviolet light passing through the compliant media contemporaneously cures the photopolymer material during the embossing.

An embedment device for use in a structural panel production line wherein a slurry is transported on a moving carrier relative to a support frame, and chopped fibers are deposited upon the slurry, includes a first elongate shaft secured to the support frame and having a first plurality of axially spaced disks, a second elongate shaft secured to the support frame and having a second plurality of axially spaced disks, the first shaft being disposed relative to the second shaft so that the disks intermesh with each other. The intermeshing relationship enhances embedment of the fibers into the slurry and also prevents clogging of the device by prematurely set slurry particles.

A filter includes first and second sheets of filter media, the second sheet being pleated and forming with the first sheet a plurality of axially extending flow channels having lateral cross-sectional shapes with two adjacent included angles each greater than 45° and less than 75°. Forming apparatus and methods are provided.

Here is disclosed a liquid-absorbent material molding drum for making liquid-absorbent materials to be incorporated in disposable diapers or the like. A molding depression is formed on its bottom with a plurality of protrusions each protruding outward in a diametrical direction of the drum and being relatively long in a circumferential direction of the drum. These protrusions are continuously arranged in the circumferential direction but distanced one from another by a predetermined dimension in an axial direction of the drum.

A crosslaminate is formed from two oriented plies of thermoplastic polymer material, arranged so that their orientation directions cross one another, the plies being heat sealed together. Each ply is semi-fibrillated, that is consist of linear thin regions of biaxially oriented material and thicker linear bosses between the thinner regions. The webs are sealed primarily through bonds formed at the intersection of the bosses (thicker regions). The array of bosses has a division less than 2 mm. The laminate has improved aesthetic and strength properties. A method for forming the crosslaminate involves segmental stretching of the material to form the thinner regions, and apparatus comprising intermeshing grooved stretching rollers having sharp-edged crests is described.

A fabrication method of forming a thermoplastic composite laminate material with tailored and varying thickness in a continuous process. This process utilizes automated equipment or hand lay-up to collate parts or components into a multi-layer stack. Each stack contains all plies, including ply build-up areas, tacked in the proper location to maintain orientation and location. The consolidation tooling contains all necessary part features and is coordinated to the customized multiple ply stacks to form a single integrated thermoplastic composite laminate potentially having areas of differing thickness from these multiple ply stacks.

There is provided a fine pattern transfer, belt-shaped mold, with which a fine structure having a high aspect ratio can be formed rapidly and stably using nanoimprinting, and a fine pattern transfer system (a nanoimprint system) that employs this mold.
