Definitions

  • the present invention relates to an apparatus and a method for the production of flat metal according to the preamble of claim 1 or 5.
  • a device in which a film with a thickness 100 ⁇ m unwound from a spool first and then horizontally through a spool first set of rolls is guided with vertically arranged pairs of rolls. Subsequently is the diluted to approximately 10 ⁇ m film vertically by a second Roll set led, whose pairs of rollers are guided horizontally, thus no further pulling force is applied except gravity. Then the slide horizontally deflected and wound up on a spool.
  • DE-C-918021 describes a method for rolling sheets from a Casting, in which the cast strand is rolled by a first pair of horizontal rollers and then the compacted strand is passed through a heating space. Then it will be the strand is introduced from below into another horizontal pair of rolls and on compacted. Now, the strand is deflected horizontally and discharged into a heating pit, where he can hang out.
