Twin Box Slitter® for Converting

Product Description

Make your corrugated box production process more efficient with the Twin Box Slitter (TBS).

The Twin Box Slitter® is a unique converting machine. The addition of a Twin Box Slitter enables box plants to double the production of Flexo Folder Gluers by running two-up boxes. These boxes are slit by the Twin Box Slitter creating two boxes.  Once the boxes are separated, they are ready to be bundled. This process allows manufacturers with a mid-sized Flexo Folder Gluer to efficiently create a wide range of corrugated box sizes from very small to large on one machine with the potential to double productivity at the same time.

Product Features

The Twin Box Slitter® effectively doubles Flexo Folder Gluer throughput by running two-up sheets and slitting in one pass, boosting efficiency, lowering cost per box, and making better use of your current setup. You’ll cut changeovers, expand your size range on a mid-size Flexo Folder Gluer, and keep the press running instead of being idle. Precision razor slitting delivers clean edges for smooth downstream bundling, while the inline retrofit unlocks capacity in your existing footprint, often deferring a second line and major capex.

Benefits include:
  • Increased flexo folder gluer productivity
  • Industry-proven razor-slitting technology
  • Self-sharpening
  • Improved bundle stability
  • Fast machine setup
  • A sharp slit cut can boost box compression performance
  • Interface that can integrate with virtually any Flexo Folder Gluer
  • Enables production of two-up half-slotted containers (HSCs)
  • Run smaller boxes

Double Production Output

The addition of a Twin Box Slitter enables box plants to double the production of Flexo Folder Gluers by running two-up boxes.

Increase Size Diversity

The addition of a Twin Box Slitter increases your flexo folder gluer’s size range to make boxes previously only capable on a mini. 

Improve Slit Quality

Industry-proven razor-slitting technology that is self-sharpening. A sharp slit cut can boost box compression performance.

Easily Integrate with Existing Systems

The Twin Box Slitters integration with the Flexo Folder Gluer streamlines your production process and doubles your yield.

    Twin Box Slitter® for Converting

    BW Papersystems Twin Box Slitter offers its operators many benefits thanks to the machine’s highly engineered design. In addition to increasing the speed of your manufacturing process, a Twin Box Slitter offers:

    • Increased flexo folder gluer productivity
    • Industry-proven razor-slitting technology
    • Self-sharpening
    • Improved bundle stability
    • Fast machine setup
    • Sharp slit cut can boost box compression performance
    • Interface that can integrate with virtually any Flexo Folder Gluer
    • Enables production of two-up half slotted containers (HSCs)
    • Run smaller boxes

     

    The Twin Box Slitter from BW Papersystems has two machine options available. These optional add-ons are:

    • Cross-Machine Direction Transfer System: Adds a transfer section that shifts one flow sideways (cross-machine) so you can match existing downstream layouts (e.g., dual infeed to bundler/strapper, lane balancing, or space-constrained outfeeds). Choose this when your current conveyor/bundling path needs lateral offset to keep throughput smooth.
    • Spare Parts packages: An OEM-curated kit of recommended wear and critical spares matched to your Twin Box Slitter configuration so you can keep production running without delays. It typically covers fast-consumption items and key assemblies (e.g., slitting consumables and essential mechanical/electrical components) and is backed by BW’s global parts network and after-hours support for quick replenishment.

    Why Choose BW Papersystems for Your Twin Box Slitter?


    BW Papersystems makes it easy to get more boxes out of the line you already have. The Twin Box Slitter® adds capacity without adding a second Flexo Folder Gluer, helps keep changeovers down, and delivers clean, consistent cuts. All of our machines are backed by OEM parts and a team that knows these machines inside and out. We can assist with installation, operational training, and even remote troubleshooting.
