Calendering installation for the production of a reinforcing ply (600) for a tire, which has a frame (100), two extruders (200, 300) for feeding elastomer material, a reinforcing-thread feeding device (400), a calender (500) having a first pair of counter-rotating rollers, with a first working roller (52) and a first shaping roller (51), and a second pair of counter-rotating rollers, with a second working roller (53) and a second shaping roller (54), wherein a calendering nip (59) is formed between the working rolls (52, 53) in order to receive a first calendered rubber ply (57) delivered by the first pair of rollers (51, 52), a second calendered rubber ply (58) delivered by the second pair of rollers (53, 54), and the reinforcing threads (45) in order to supply the calendered reinforcing ply (600), which is conveyed to the outlet of the installation via guide rollers (62, 63).

According to the invention, the two extruders (200, 300) are superposed and arranged on either side of a horizontal plane P extending at the level of the guide rollers (62, 63).

Imprint lithography templates having leading and trailing edge borders are provided that achieve zero-gap imprinting between adjacent fields with full-feature height features provided in the pattern exclusion zones (PEZ) located between such fields. The leading edge borders include dummy features, e.g., elongated features directionally oriented parallel to the mesa edge, while the trailing edge border includes a recess extending to the mesa edges. When used in a step-and-repeat process, the trailing edge border overlaps edge portions of an adjacent imprinted field that were previously patterned by the leading edge border of the template, producing full-feature height features in the pattern exclusion zones between such fields, and avoiding gaps or open areas between such fields that otherwise lead to non-uniformity of downstream processes such as etch processes and CMP.

Methods of forming laminating adhesive articles include providing a multi-layer article, and a tool with a structured surface. The multi-layer articles include a substrate, an adhesive layer, and a liner. The multi-layer article is placed between the structured surface of the tool and a support surface that is hard and the tool is embossed against the liner by applying pressure or pressure/heat. The embossing causes the tool structures to distort the liner and the adhesive layer, and causes permanent topological changes in a portion of the adhesive layer, but does not distort the substrate. The distortion in the liner is retained upon release of the applied pressure. The portions of topologically changed adhesive can form convex structures that are permanent. Upon removal of the liner from the adhesive layer, the concave structures on the adhesive layer are unstable, but the convex structures are stable.

A press plate arrangement having a plurality of surface-structured press plates for introducing surface structures in a material to be pressed, said press plate arrangement forming a closed band structure. A method for producing a decorative panel having a surface structure that substantially matches the decorative pattern.

Arrangement information regarding shot areas is obtained in an imprinting method. When a pattern is sequentially formed in the shot areas, the attraction force of a first attraction area is reduced to less than that of the second attraction area. After the pattern is formed in the shot area corresponding to the first attraction area, the attraction forces of the first and second attraction areas are changed. The position information regarding the shot area corresponding to the second attraction area is obtained, which is compared with the position information regarding the shot area corresponding to the second attraction area based on the arrangement information. If the difference between the compared position information is a threshold value or less, positioning of a substrate and a mold is achieved using the arrangement information. If the difference is greater than the threshold value, the arrangement information regarding the shot areas is obtained again.

Gelatinous materials combined with the Colloidal Silver additive to formulate an antimicrobial product having cushioning properties. Embodiments of the present invention can include gelatinous materials selected from a group consisting of thermosetting polymer, Styrene-Ethylene-Butadiene-Styrene polymer (SEBS), Thermoplastic Elastomer (TPE), and Polyurethane (PU) gelatin with and without a raised geometry on an outer surface.

A new way to design lightweight, strong, material efficient, extruded and pultruded profiles, profile segments (4) and surfaces produced in profile production with rotating dies creating superior resistance to compression, bending and buckling, higher energy absorption and right strength in the right place, by: varying the thickness along (_t)+across the direction of extrusion, making reinforcing patterns (2, 3), vary the profile thickness (t, _t), and in some cases vary angles (10, 11) and pattern (2, 3) which increases the profile segments/surface resistance against compression, bending and buckling relative to the amount of material used and resulting in that one can make optimized beams and surfaces that have superior properties in terms of strength/weight, stiffness/weight ratio, mechanical energy absorption/weight unit, deformation and natural frequency, thermal transfer capacity, the breaking of the laminar flow, increased/optimized surface for chemical and/or electrochemical reaction etc.

The present disclosure provides a microstructured article (830, 930) including a thermoplastic polymer shaped to have a curve. At least a portion of the curve includes a microstructured surface (1010B, 10, 1110A, 200, 300, 400, 500, 600, 810, 840, 910, 940) of utilitarian discontinuities and the microstructured surface (101B, 10, 1110A, 200, 300, 400, 500, 600, 810, 840, 910, 940) includes peak structures and adjacent valleys (810, 910).

A method of making the microstructured articles is also provided including a) obtaining a tool (820, 920) shaped to include at least one of a protrusion or a concavity; b) disposing a microstructured film (800A, 800C, 900) on at least a portion of the tool (820, 920) including the protrusion and/or the concavity; and c) thermoforming a single piece of thermoplastic polymer onto the tool (820, 920) to form a microstructured article (830, 930) shaped to include a curve. The curve is an inverse of the protrusion or the concavity of the tool (820, 920).
