This brand new downstacker is fully automatic and is available as a single or double level configuration.


From the dry-end sheets are delivered on to the downstacker where they are first shingled and aligned on the braking section via a guided vacuum belt and an automatically controlled brush group assembly. The control system, according to a personalised pressure curve set at each individual installation, dynamically adjusts the variable pressure on each of the five brushes according to the sheet width, sheet length, the flute type, and actual running line speed being run


Stack changes are accomplished via a moving clamp. The result is that stack/order changes can be carried out at the highest line speeds, while continuously maintaining the best stack quality available in the market.

Thanks to the multiple independent belt sections and intelligent machine program, multiple orders can be managed on the stacker at the same time, ensuring very short order capability.  A counterweight arrangement on the stacker elevator decks reduces stack ejection cycle times by more than one-third, not only improving stack quality but also increasing production speed capabilities. 


To further reduce the cycle time this machine is equipped with an in-line reverse discharge feature that allows the fast and stable removal of the narrowest sheet sizes.  Alternatively it can be equipped with a standard lateral discharge according to each customer's needs and space requirements.
