摘要： Film articles with dual-sided structures are ones in which both of the major surfaces of the film have a structured surface. The structured film articles have a first major surface and second major surface, where each surface has a plurality of spaced apart protrusions forming a repeating pattern. Each repeating pattern has a major axis, where the major axis is one of the major axes in the translational direction of the repeating pattern. The major axis of the repeating pattern on the second major surface forms an oblique angle with the major axis on the first major surface, where the angle is in the range of 10-90% of the angle of rotational symmetry of the repeating pattern. The structured film is a unitary substrate. The structured film articles are prepared by providing a flowable material composition having two major surfaces and simultaneously contacting the major surfaces with a first microstructuring tool, and a second microstructuring tool. Each microstructuring tool has a structured surface including a pattern of a plurality of depressions.

摘要： A method of molding resin on a flexible substrate includes forming discrete regions of resin and forcing resin of at least some of the regions into molding cavities to form a respective array of resin projections extending from a resin base of the regions. Forming the discrete regions of resin includes depositing molten resin directly onto either the substrate or a surface in which the cavities are defined. The resin is deposited as the substrate moves in a processing direction, and the resin is deposited by resin sources spaced from each other along the processing direction.

摘要： Discrete male touch fastener elements are molded of thermoplastic resin extending from a common, flexible base sheet, by introducing molten resin to a molding nip between two counter-rotating rolls consisting of a mold roll and a pressure roll arranged such that their rotation axes are parallel and together define a common plane containing each of the rotation axes. Solidified resin is stripped from molding cavities of the mold roll after the cavities have passed a rotating reaction roll forming a pressure nip with the mold roll. The reaction roll is spaced from the pressure roll by a distance less than an outer diameter of the mold roll, and the mold roll is simultaneously held against both the pressure roll and the reaction roll in a non-planar roll stack.

摘要： Roller assembly for forming adjacent curved surfaces in a composite gap filler member includes a first roller supported by a first support member, a second roller supported by a second support member and a support including a surface. First roller and the second roller are in contact with one another and in contact with the surface. With rotation of the first roller about a third axis and with at least one of the first roller or second roller moved relative to the other such that the first roller maintains contact with the second roller and the first roller and the second roller maintain contact with the surface, such that the first roller, second roller and the surface form an aperture having a first curved side having a first radius adjacent to a second curved side having a second radius wherein the first radius and second radius are unequal.

摘要： Aspects of the disclosure relate to methods for making large areas of high aspect ratio micro or nanostructured foil using existing extrusion coating equipment. A method is disclosed for producing a high aspect ratio micro- or nanostructured thermoplastic polymer foil, or a nanostructured thermoplastic polymer coating on a carrier foil, comprising at least one high aspect ratio nanostructured surface area. The method comprises applying a high aspect ratio nanostructured surface on an extrusion coating roller and maintaining the temperature of the roller below the solidification temperature of the thermoplastic material. A thermoplastic foil and a thermoplastic coating made by the method is also disclosed.

摘要： Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.

摘要： An air/gas filter medium is comprised of a substantially homogeneous core layer of feather down clusters held together by a binder to form a 3-dimensional interconnected filament structure throughout the core. The filament structure forms air pocket and connect and trap the feather down clusters which form minute air pockets between its filaments and hairs in which undesirable substances from an air/gas flow therethrough are captured. An air permeable scrim sheet is retained on a surface of the down cluster core. The down cluster core is compressed to a predetermined density to modify the average size of said minute air pockets to trap known undesirable substances from the air/gas flow.

摘要： A surface fastener molding apparatus includes a supporting structure and a second supporting structure for axially supporting a mold roll in a rotatable manner at a first end side and a second end side of the mold roll which is opposite to the first end side. The mold roll includes a circumferential surface in which a plurality of mold cavities for molding engaging elements of the surface fastener is provided. A first linear driving means and second linear driving means are provided which are for, respectively, advancing or retracting the first supporting structure and the second supporting structure. The degree of closeness between the extruding nozzle and the mold roll is regulatable across the first end side and the second end side of the mold roll, based on at least one activation of the first driving means and the second driving means.
