How the RubbA Cuts Ejection Rubber Waste
RubbASave is the waste-reduction software built into the Serviform RubbA and RubbA1000 ejection rubber cutting tables. A projector maps every cutting path onto the rubber sheet before the first cut, so the operator can position parts to leave less scrap. The RubbA cuts with a pneumatic oscillating knife instead of a waterjet, so cut rubber is ready to use right away, with no drying time.

What is RubbASave?
Ejection rubber is bought by the sheet and cut to fit each die, so every scrap left on the table is a material cost. RubbASave is the software on the Serviform RubbA that tackles that scrap before the knife moves.
The RubbA has a working-table projector. RubbASave uses it to map the cutting paths directly onto the sheet. The operator sees where each part will land and can reposition parts to use the rubber well. Nothing is cut until that layout is right.
Every job leaves scrap pieces on the table. RubbASave lets you put those leftovers to work. Because the operator can see each cutting path on the table, parts can be fitted onto leftover pieces, even the smallest ones, instead of going straight to fresh rubber.
Serviform America does not publish a fixed waste-reduction percentage. The saving depends on your die sizes, your sheet size and how parts are placed.
How does RubbASave work on the RubbA?
- Load the die file. The RubbA accepts .DXF, .DD3, .DDS and .CF2 data.
- Project the cutting paths. The projector maps every path onto the rubber sheet before the first cut.
- Position the parts. The operator arranges parts on the sheet to minimize scrap.
- Cut with the oscillating knife. A pneumatic knife makes a through cut, or a kiss cut for self-adhesive rubber.
- Rubber is ready to be placed. After the rubber is precision cut, you can place it on the die right away. Place it by hand, or send the file to the Rubbot 2100 for automatic pick and place.

Serviform RubbaSaveServiform America on YouTube · Published March 31, 2026How does the RubbA compare to a waterjet?
Waterjets were long the standard for cutting ejection rubber. The RubbA replaces the waterjet with a pneumatic oscillating knife. Our full breakdown is in Waterjet vs. Oscillating Knife Systems: The Best Way to Cut Ejection Rubber in Die Making.
| Waterjet | Serviform RubbA | |
|---|---|---|
| Operating inputs | Water, power and abrasives such as garnet | Power and compressed air |
| Wear parts | Pumps, nozzles, seals and filters wear under pressure and grit | Quick, low-cost blade changes, with no abrasive wear |
| Cleanup | Slurry that needs cleanup and water management | No slurry, no plumbing |
| Drying time | Wet rubber has to dry before use | None. Rubber is ready to use right away |
| Footprint | Needs space and infrastructure | Compact, fits a die shop without modification |
| Waste planning | Not part of the cutting system | RubbASave projects the layout on the sheet |

Where does RubbASave fit in the rubber workflow?
RubbASave handles the first half of the job: planning the layout and cutting the rubber. The RubbA then connects to the Rubbot 2100, the first fully automatic robot to pick and place cut ejection material. The Rubbot 2100 receives cutting files from the RubbA, so the cut and the placement stay in one workflow.
The RubbA comes in two sizes. The RubbA1000 gives die shops that run large dies at high volume the same cutting system, the same RubbASave and the same zero drying time on a larger table.
Case study: Davis & Pierce Die Service adds a RubbA
Davis & Pierce Die Service in Kansas City has been in business since 1973. The shop added a Serviform RubbA ejection rubber cutting machine to its die shop.
Read the Davis & Pierce case study to see how the shop made the move to the RubbA.
What do die shops say?
“No more waiting on drying time like with our old waterjet—production moves faster than ever with the RubbA!”
RubbASave and RubbA questions
What is RubbASave software?
RubbASave is the waste-reduction software on the Serviform RubbA and RubbA1000 ejection rubber cutting tables. A projector maps each cutting path onto the rubber sheet before the first cut, so the operator can position parts to minimize scrap. It is listed as a standard feature of the RubbA.
How does RubbASave reduce ejection rubber waste?
RubbASave previews every cutting path directly on the sheet. The operator sees the layout before cutting and positions parts to leave less scrap. Serviform America does not publish a fixed waste-reduction percentage, because the result depends on die sizes, sheet size and part placement.
What file formats does the RubbA accept?
The RubbA accepts .DXF, .DD3, .DDS and .CF2 files. It runs on SDDS, Serviform's Windows-based die making software, together with RubbASave.
How does the RubbA compare to waterjet cutting for ejection rubber?
The RubbA cuts with a pneumatic oscillating knife instead of a waterjet. That removes the water, abrasive and slurry cleanup, and cut rubber comes off the table dry and ready to place, with no drying time. Serviform states that the oscillating knife matches waterjet cut quality.
Can the RubbA kiss-cut self-adhesive rubber?
Yes. Software-controlled micro-adjustment of cutting depth lets the knife cut through the rubber without cutting the liner, so the rubber is ready for clean pickup and placement.
What sizes does the RubbA come in?
Two. The RubbA has a working area of 1000 x 600 mm (39.37 x 23.62 in). The RubbA1000 has a working area of 1200 x 1000 mm (47.24 x 39.37 in) for larger dies. Both use the same cutting system and RubbASave.
Does the RubbA work with the Rubbot 2100?
Yes. The RubbA sends cutting files to the Rubbot 2100, Serviform's automatic robot that picks and places cut ejection material.
What does the RubbA need to run?
Power supply of 400V/220V +/-10%, 50/60 Hz, 3-phase plus neutral. Compressed air at 9 bar (130 psi), with average consumption of 450 Nl/min (15 CFM) of clean, dry air.
Who services the RubbA in North America?
Serviform America. Factory-trained technicians are located across the U.S., parts and customer service are fully stocked in Atlanta, GA, and remote diagnostics are available.
Is it RubbASave, RubbaSave or RubbA Save?
They are the same software. Serviform writes it RubbASave in the machine specifications and RubbaSave in some videos and articles. Shops also search for it as Rubba Save.
