摘要： A stretch composite fabric comprises a sintered expanded porous polytetrafluoroethylene film and a stretch cloth laminated to each other while maintaining a flat state. The stretch composite fabric has a tensile stress at 10% elongation, as measured in at least one direction, of 1.8 N/15 mm or less. When a 5 cm-width test piece of the stretch composite fabric is stretched in a length direction under a load of 300 g and then released from the stress, an elongation recovery R of the stretch composite fabric, which is given by the following equation, is preferably 700 or more. R=(L2−L3)/(L2−L1)×100 (In the equation, L1, L2, and L3 represent the lengths of the composite fabric before the load is applied, when the load is applied, and after the load is removed, respectively.)

摘要： There is described a method for wrapping an article using a web of packaging film having at least one tar line thereon in the MD, the method comprising the steps of: (a) forming at regular intervals in the MD a tab on the film, the tab having a free end connected by free sides to an opposite end of the tab attached to the film, the tab being positioned on the film so the axis of at least one tear line in the MD passes through both ends of the tab; (b) severing the film web to form sheets by cutting substantially along an axis across the TD of the web, the axis passing across the tab between its ends, where the tab along said axis is not substantially severed there through so the tab protrudes from the leading edge of the sheet; (c) wrapping a sheet formed from step (b) around an article to form a tube with the cut sides of the sheet overlapping, where the free end of the tab lies on the top of the overlap on the outside of the tube and where the cut sides of the sheet overlap at least to the extent that the tab in the film on the top surface overlaps with film underneath, and (d) sealing the film together within the overlap region by a sealing means which: (i) seals more strongly in the overlap region outside a tear line region inside the overlap, where the tear line region is defined by the cut edges of the overlap region (ex TD) and a pair of axes parallel to the non-cut sides of the film sheet (ex MD) each axis passing through the respective widest points of the side of the tab; so the free end of the tab is either unsealed or only weakly sealed to the film; and (e) wrapping the ends of the tube around the article and sealing the ends to form a sealed package around the article, the package readily openable by pulling the free tab end to initiate tearing along the tear line. Packaging (such as cigarette cartons) wrapped with films by this method are also described.

摘要： A device and method for the manufacture of medical devices, specifically, endovascular grafts, or sections thereof. Layers of fusible material are disposed upon a shape forming member and seams formed between the layers in a configuration that can produce inflatable channels in desired portions of the graft. After creation of the seams, the fusible material of the inflatable channels may be fixed while the channels are in an expanded state. A five axis robotic seam forming apparatus may be used to create the seams in the layers of fusible material.

摘要： An article (2) in which at least part of a surface (8) of a polymeric element has an embossed pattern (6). The article may be either heat-recoverable or non-heat-recoverable. If the article is heat-recoverable, when heated the article recovers and the embossed surface becomes substantially smooth. The change in surface texture can be used to indicate that sufficient heat has been applied to the article to achieve adequate recovery and/or to adequately melt an attached adhesive layer (10). In another embodiment, the article (2) is in the form of a patch (14) which can be used to secure the opposing longitudinal edges of heat-recoverable article which is in the form of a wraparound sheet.

摘要： A novel method and apparatus are provided for making an improved welded joint between overlapping lengths of thermoplastic strap. The welded joint includes a central region and an adjacent peripheral region. The pressure on the strap joint during formation is released first in the peripheral region and subsequently in the central region. An embodiment of the apparatus for making such a joint includes an anvil, a central strap-engaging member, a peripheral strap engaging member, and a mechanism for moving the anvil sequentially to three positions. At a first position the overlapping strap lengths are pressed between the anvil and both the central and peripheral strap-engaging members. In the second position of the anvil the peripheral strap-engaging member does not press against the strap lengths while the central strap-engaging member continues to press the strap lengths against the anvil. In the third position of the anvil the anvil and strap-engaging members are sufficiently spaced apart to release all of the pressure on the strap lengths.
