  • Extrusion head
    Patent number: 7374412
    Abstract: In an extrusion head and an extrusion method for the production of a tubular multilayer preform the extrusion head includes at least two feed paths for feeding plasticised plastic material from one or more extruders to an annular passage arrangement. The annular passage arrangement includes mutually concentric annular passages forming mutually separate flow paths for the various layers of the preform. An annular gap nozzle has an annular gap communicating with the annular passage arrangement, and at least one flow passage communicates with an annular passage of the annular passage arrangement, for the introduction of a translucent viewing strip. The flow passage communicates with the annular passage in question upstream of the annular gap in the region of separation of the flow paths.

  • Fuel container
    Publication number: 20040178205
    Abstract: The invention concerns a fuel container of plastic material such as a motor vehicle fuel tank, comprising one or more welded seams as seam locations for the body of the container and/or as connecting or sealing seams between the container wall in the region of openings and closure elements or covers welded thereto. At least some of the welded seams are at least partially penetrated by a duct which extends in the longitudinal direction in the seam and which can be filled with air and vented.
