The Vipro Stacker operates fully independent and is fit to be connected to a ¾ -automatic screen printing machine. The construction of the hydraulic lifting tray allows a pallet wagon to be moved in on the same floor to remove the pallet. Light sensible photocells register the arrival of a sheet; the joggers open and after the sheet has been stacked they close on a short pulse. Another set of light sensible photocells registers the stack height, allowing it to keep the same level. An optical signal indicates the stacker tray to be filled.

The input roller speed is stepless adjustable. The amount of air, blown underneath the sheet, can precisely be regulated. Standard the Vipro Stacker is equipped with a mirror, it's own hydraulic pump and a blow air fan.
