Multiple decoiling line 6x5000kg (11000lbs)

The efficient production of blanks requires keeping a wide range of entirely different coils on hand. To allow rapid access to different sheets, we developed a multiple decoiling system featuring automatic sheet change-over in less than 1 minute.


Our objectives in developing this line were:


  • fully automatic sheet change-over in the shortest possible time
  • programmable upper straightening shafts adjustment
  • programmable setting of slitting knives
  • the simplest possible operating
  • retrofitting
  • lower acquisition costs
  • one-worker operation
  • space savings


The Forstner fully-automatic decoiling, straightening, slitting and cut to length line offers features that an industrial production manager has only dreamed about. This line fulfils the demanding requirements of any sheet metal working industry.



  • constant quality: The blanks are precise and free of burrs.
  • lower material cost: The purchase price for large coils is lower than for small coils or sheets.
  • less waste: You slit wide coils accurately and have fewer residual strips.
  • lower personnel cost: The system is operated by one person. You reduce cutting time considerably.
  • more storage capacity: You only need one wide coil per material type.
  • shortened production time: The handling of all types of materials is substantially rationalized by the use of larger coils.

  • more space due to compact design
  • easy loading by cantilever decoilers and hydraulic expansion of the mandrels
  • smooth decoiling and recoiling by powered decoilers
  • smooth infeeding of coils across powered sheet guideways into the coil selector
  • automatic access to up to three different coils by the coil selector
  • mark free straightening by programmable upper straightening shafts adjustment
  • automatic adjustment of up to 10 pairs of slitting knives
  • precise, burr-free and economic cutting to length by a guillotine shear
  • automatic sheet change-over in less than 1 minute
  • simplest operation with logical icons instead of text by Siemens touch panel
