Abstract:
A foam cushion pad formation assembly that includes a conveyance assembly having at least one moving conveyor component presenting a pad shape formation surface, which surface is convoluted and arranged to shape sealed enclosures of a pad chain received by the conveyance assembly. A separation device is provided to separate shaped pads of the pad chain received by said conveyor device. The shaped pads include convoluted surface that are formed by way of gripping projection and recesses combinations in the moving conveyor component. Embodiments include sensing for non separated pads from a downstream end of the bag chain, pad chain separation enhancement devices, and various control system including the requirement of confirmation of separation before feeding a new pad enclosure as in one containing liquid polyurethane precursor chemicals. An embodiment includes a pad chain path disruption sensor and a form feed control which implements the formation of pad enclosures free of filler material in a bridging region between the outlet end of the enclosure formation means and the conveyance assembly.

Die Doppelbandanlage umfasst eine Zufuhrvorrichtung zur diskontinuierlichen oder kontinuierlichen Zufuhr einer ersten Platte, eine Zufuhrvorrichtung zur Zufuhr eines ersten seitlichen Begrenzungsprofils, eine Einbringvorrichtung zur Einbringung eine aufschäumenden Kunststoffmaterials auf die erste Platte sowie zwischen das erste seitliche Begrenzungsprofil und eine dem ersten seitlichen Begrenzungsprofil gegenüberliegende, seitliche Randbegrenzung eine Doppelband-Vorrichtung mit einem Ober-und einem Unterband. Erfindungsgemäß ist in dem der Platte gegenüberliegenden Band der Doppelband-Vorrichtung umlaufend zumindest ein Vorsprung zur Ausbildung einer gegenüber einer ebenen Oberfläche zurückspringenden Aufnahme (24) in dem aufgeschäumten Kunststoffmaterial vorgesehen.
Abstract:
Bei einem gewellten wärmegedämmten Leitungsrohr für Flüssigkeiten, z.B. für Fernwärmenetze, ist mindestens ein Mediumsrohr (2) aus Kunststoff oder Metall von einer Wärmedämmschicht (14) umgeben, die z.B. aus einem Polyurethanschaum besteht. Die Wellung (25, 26) des Aussenmantels (15) aus Kunststoff ist so gebildet, dass sowohl die Wellentäler (25) als auch die Wellenberge (26) rund, insbesondere kreisrund geformt sind. Ferner ist die Wellung so dimensioniert, dass bei einem Aussendurchmesserbereich des Leitungsrohrs von 63 mm bis 202 mm die Welltiefe T in einem Bereich von 4,5 mm bis 8 mm liegt. Diese Formgebung und Dimensionierung des Leitungsrohrs ergibt eine sehr gute Biegbarkeit und damit Aufrollbarkeit des Rohrs für dessen Transport.
Abstract:
An electromagnetic interference shield that meets flammability standards for use in electronic equipment enclosures such as computer cabinets and other electronics includes a resilient foam core, an expandable carbon graphite layer, and a metallized fabric outer layer. The shield may be manufactured on a process line which forms, laminates, and bonds the elements together.

Abstract:
An apparatus for the continuous production of an auxetic foam, comprising a tunnel (17) comprising a compression section with an inlet and an outlet for compressing foam in at least one axis as it moves from the inlet to the outlet, means (13, 14, 15, 16) to propel a foam material through the tunnel (17) from the inlet to the outlet, and heating means to heat foam passing through the compression section (11) to a temperature higher than its glass transition temperature.
Abstract:
A foam roofing underlayment (14, 46) is provided with a reinforcement membrane (24) having an array of fastener elements (26) across a broad face for engaging fastener elements (36) on a flexible roof membrane (16, 116, 216, 316, 416). The underlayment (14, 46) is formed by molding foam (70) between the reinforcement membrane (24) and a carrier sheet (62). The underlayment (14, 46) is secured to the roof (12, 206, 306) using washers (20) having fastener elements (26)a for engaging the fastener elements (36) of the flexible roof membrane (16, 116, 216, 316, 416). An anti-peel flap (25) with fastener elements (26a) is provided around the periphery of the washers (20a). A slip sheet (150) is used between the underlayment (114) and the flexible roof membrane (116) to permit accurate positioning of the flexible roof membrane (116) prior to engagement of the fastener elements (126, 136). The interstices between the fastener elements (26, 36 126, 136) provide lateral moisture paths to vents (152) in the flexible roof membrane (116).
