Twin Box Slitter Applications

The Twin Box Slitter from BW Papersystems increases the productivity of the flexo, for box makers by the creating the ability to run minimums usually reserved for a “mini” Flexo Folder Gluer on a midsize FFG.

The Twin Box Slitter operates in-line with a mid-sized Flexo Folder Gluer to increase the number of sizes the mid-range FFG can produce on a single machine. With this, our customers can experience almost double their productivity. 

Slitting Machine Capabilities

The Twin Box Slitter begins to operate after the Flexo Folder Gluer or Casemaker manufactures the 2-up corrugated regular slotted (RSC) or half-slotted container (HSC).
Once the RSC or HSC reaches the Twin Box Slitter, it is then split down the middle. This split creates two boxes out of one feed sheet, giving you the power to double your production rates.

After being split into two, the boxes are then ready to be bundled.
The Twin Box Slitters integration with the Flexo Folder Gluer streamlines your production process and doubles your yield.
