摘要： A process for producing a hollow aluminum extrudate for use in a vacuum comprising the steps of hermetically closing the forward open end of a hollow shaped material immediately after extrusion, subsequently extruding a predetermined length of shaped material, cutting off the predetermined length of extruded material and hermetically closing the cut end thereof at the same time, and cutting off the closed ends. During extrusion, the inner surface of the hollow portion of the shaped material is substantially held out of contact with the atmosphere to inhibit a hydrous oxide on the inner surface while permitting formation of a compact oxide film thereon.

摘要： A machine and method for corrugating a metal foil strip utilizes an enclosure defining a chamber and a controllable heat source for heating the chamber. The chamber may optionally include at least one gas that is also heated by the heat source. At least one tool set received in the chamber forms corrugations in the metal foil strip. Foil entry feeder elements supply and guide the metal foil strip from outside the chamber into the chamber and to the tool set. A drive for the tool set is mounted outside the chamber and coupled to the tool set to actuate the tool set. Foil exit delivery elements guide the strip from the tool set and out of the chamber. Where required to prevent oxidation of the foil strip, a source supplying an inert gas to the chamber at a controlled rate is used.
