A twin-sheet thermoforming process for the manufacture of vehicle headliners. In the process a first sheet and second sheet of SuperLite material are mounted onto respective frames. The frames transfer the sheets into an oven, where they are heated to a desired temperature using IR. The first sheet is combined with a cover-stock material using compression molding forming a covered first headliner part. The covered first headliner part is then transferred to a second mold station. The second sheet is heated and then transferred from the oven to the second mold station where it is vacuum-formed on the upper half mold, forming a second headliner part. The upper and lower mold halves are pressed together fusing and sealing the first and second headliner parts into a unified part. The unified part is then unloaded and trimmed as necessary forming a headliner. The SuperLite material used to form the headliner is a sheet of low pressure, thermoformable, thermoplastic composite comprised of polypropylene and long chopped glass fibers.

A method of producing a spread multi-filament bundle and an apparatus is used in which an arbitrary number of multi-filament bundles of higher strength are simultaneously spread with high speed and a high-quality. A spread multi-filament bundle or sheet with the component monofilaments thereof aligned in parallel widthwise and uniformly distributed in density is produced. The respective multi-filament bundles fed from a yarn supplier or a creel are subjected to fluctuation of the tensile force applied thereto alternatively between tension and relaxation and the respective bundles as subjected to such fluctuation are passed in succession through a fluid flowing spreader.

A process for forming a patterned thin film structure on a substrate or in-mold decoration film is disclosed. A pattern is printed with a material, such as a masking coating or ink, on the substrate, the pattern being such that, in one embodiment, the desired structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structure.

A molded foam-encased integrated flexible support device includes an innerspring positioned upon a three-dimensional thermoplastic foam deck as a flexible foundation, and a molded foam encasement which structurally integrates the foam deck with the innerspring by attachment to perimeter coils of the innerspring. A sculpted foam topper is adhesively bonded to a support surface of the foam-encased innerspring, forming a unitized mattress or support structure with fully integrated innerspring and internal and external foam components. The sculpted foam topper is designed with varying contours and densities to provide the desired support and feel characteristics for different comfort profiles. The foam encased innerspring with internal three-dimensional foam structures is upholstered for use as a mattress, seating, or other flexible support structure.

A microfluidic device comprising one, two, three or more enclosed microchannel structures, each of which comprises a) an inlet arrangement with an inlet opening for liquid, b)a reaction microcavity (RM1) downstream to the inlet opening, and c) an upstream section that is located between the inlet opening and the reaction microcavity (RM1) and is defined between two planar substrates made of plastic material which substrates are common for said microchannel structures. The characteristic feature is that the inner wall in said upstream section exposes a hydrophilic surface area with an underlying base layer comprising metal oxide. In one aspect the microfluidic device as such is covered.

Decorative system composites and methods for forming the same are described. The composites employ new and improved support film systems that have enhanced tensile strength under typical thermoforming conditions, including elevated temperatures. An optional release film can be used in conjunction with the support film. The support film is particularly suitable for use with decorative films used to impart a surface effect, such as paint or color-containing film systems, to a thermoformed plastic component. The support film systems also possess enhanced bag / sag / drape control characteristics.
