  • Patent number: 8257500
    Abstract: In a transport device for elongated substrates, especially in hot processes, which includes an essentially rectangular frame, formed by longitudinal and transverse spars connected to each other, in which at least three transverse spars are provided between two longitudinal spars, at least one transverse spar is made from a material, whose heat expansion coefficient differs from the heat expansion coefficient of the material of the other transverse spars or/and at least one transverse spar is connected force-free to at least one transverse support or/and at least one transverse spar is formed from an open profile.
    Type: Grant
    Filed: October 8, 2008
    Date of Patent: September 4, 2012
    Assignee: Von Ardenne Anlagentechnik GmbH
    Inventors: Johannes Struempfel, Reinhardt Bauer, Andreas Heisig, Andre Ulbricht, Steffen Goerke, Heiko Richter, Falk Schwerdtfeger
  • Patent number: 8033781
    Abstract: A transport device for transporting elongated substrates through a vacuum coating system comprises an essentially rectangular frame and two groups of holding elements, which are rotatably mounted on opposite sides of the frame in such a manner that any pair of opposite holding elements can be connected to both ends of a substrate. Furthermore, at least one retainer bar is provided that is operatively connected to a group of holding elements in such a manner that the holding elements of this group are moveable in order to increase or decrease by choice their distance from the holding elements of the other group. Also provided are a loading and unloading device for loading and unloading the transport device, and a method for loading and unloading the transport device.
