  • Publication number: 20090157020
    Abstract: A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain. The “kinks” in the second copolyester backbone reduce its melting point and degree of crystallinity, which have an influence on its physical properties (e.g.

  • Publication number: 20090088039
    Abstract: A method for producing a noise insulation piece of mass/spring construction. The mass has, at least before a deep draw process, at least one locally defined region, with a different weight per area from the other regions. After the deep draw process, the spring layer made from an elastic light material such as two-component polyurethane foam or a mixed non-woven fiber is applied. The locally different weight per area of the mass is achieved by means of application of a granulate to a base mass layer in particular in locally differing amounts and/or thicknesses, wherein the granulate is fixed to itself and to the base mass layer by means of sintering. After deep drawing, the desired weight per area of the mass can be achieved independent of the degree of drawing. The granulate can alternatively also be applied to a thin and lightweight support layer in locally required amounts or thicknesses.

  • Patent number: 6808665
    Abstract: In a thermoforming system for masked polymer substrate sheets, a temperature resistant, non-stick coating is applied to a sheet of a polymer substrate material. The coated sheet is positioned on a flexible platen positioned over a mold having a predetermined shape. Heat is applied until the polymer reaches a thermoforming temperature and softens, whereupon the platen is lowered to stretch over and cover the mold. When the sheet begins to conform to the mold, the heat is withdrawn and a second platen is lowered over the sheet to urge it into conformance with the mold. The temperature resistant coating can be applied over an existing polymer film masking, and rapidly cures to form a non-stick surface which prevents adhesion of the masked polymer sheet to the platen surfaces.

  • Publication number: 20030067092
    Abstract: The invention herein relates to a method and apparatus for forming (or cold-forming) an embossed blister from a laminated film wherein an indicia is formed on the base of the blister. In particular, the invention involves a single pass process of combining the formation of a blister and the formation of an indicia (embossing) on the blister, wherein the blister-forming pin contains a face with an indicia and is adapted to controllably stretch the laminated film during blister formation to minimize stretching of the film at the base of the blister. The invention is particularly useful in manufacturing processes which involve the formation of blisters having laminated films which contain a metal foil and polymer layer, wherein improved control in the stretching of the laminate during blister formation is desirable.

  • Patent number: 6458308
    Abstract: A mold for molding a composite article has an upper half mold, a lower half mold having a base and a core mounted on the base, and a pressure plate. A plurality of holes are formed in the upper surface of the pressure plate, and springs are placed in the holes. A laminated sheet formed by laminating woven fabrics is placed on the core, and the pressure plate is put on the laminated sheet so as to press a part of the laminated sheet against the core by its weight without creasing the part of the laminated sheet. When joined to the lower mold, the upper mold compresses the springs to compress the part of the laminated sheet firmly between the pressure plate and the core, and then bends the laminated sheet along the side surfaces of the core so that the laminated sheet is shaped in a predetermined shape.
