G3 Male Secondary Creasing Rings
Sauer System offers G3 male creasing rings for EVOL 84, EVOL 100, and EVOL 115 flexo folder-gluers that are specifically designed to reduce gap variation and improve folding.
Improved Profile Geometry
The G3 male profile incorporates geometry that conditions the board and provides relief for the inside liner, encouraging it to tuck into the grooves created between the tapered scoring insert and rounded shoulders.
The result is improved folding, a reduction in gap variation that exceeds manufacturing specifications, and a higher quality finished box.
Head-to-Head Tests
G3 creasing rings have been tested against OEM creasing rings in numerous head-to-head empirical data-driven tests, with other variables held constant. The testing included a wide variety of board grades, from pre-print and heavy liners to heavily recycled board, and spanned a range of EVOL machines vintages, from early vintage EVOL 84 machines to brand new EVOL 115 machines.
In every case, the G3 rings significantly outperformed the OEM rings.
Replaceable Hardened Scoring Inserts
A hallmark benefit of the G3 is the ability to maintain the integrity of the profile by replacing the insert ring that performs the creasing action. In addition, modular inserts allow the end user to customize the profile by tweaking the height and design of the insert.
G3 Advantages
- Reduced Gap Variation
- Improved Fold Consistency
- Increased Productivity
- Reduced Rolling Scores
- Reduced Liner Fracturing
- Reduced Waste and Rejects
- Lower Cost of Ownership
- Guaranteed Improved Performance

Precision-Ground G3 Female Creasing Rings
Sauer System offers enhanced primary and secondary female creasing rings for EVOL 84, EVOL 100, and EVOL 115 flexo folder-gluers. The Sauer style females have two major advantages over the OEM females.
Precision Grinding Process
Second, Sauer females have their outer diameter precision-ground using a proprietary process. The diameter is held within +/- .003”. This ensures consistency across the shaft, allowing for increased scoring pressure.
Improved Profile Geometry
First, the females incorporate a channel style profile that allows the middle of the profile to act softer than the edges, reducing cracking on the score line while maintaining harder polyurethane on the edges for added crush. This also allows for a harder durometer to be used which results in a longer lasting anvil.
Recover Service
Sauer System offers a full “recover” service for EVOL primary and secondary female creasing rings. They can be recovered in any specified durometer and are precision ground to a precise diameter.

Hold-Down Roller Eliminator (HDRE)
EVOL flexo folder-gluers utilize a series of hold-down rollers as the primary means of controlling sheets as they travel through the folding section. Spring-loaded rollers apply downward pressure on the folding belts and sheets as they transition from the die cutter to the counter-ejector. Over time, the rollers wear out and fail at different rates leading to uneven sheet transfer, folding issues, twisting and skewing, and eventually jam-ups. The roller issues create downtime for maintenance and high replacement cost.
Improved concept
Sauer System provides the HDRE: a solution that eliminates the hold-down rollers altogether, instead replacing them with a spring-loaded, self-adjusting assembly. The HDRE provides a nearly continuous nip with almost no failure points. There are no replacement parts and no routine maintenance required to maintain the system.
HDRE Advantages
- Reduced Gap Variation
- Improved Fold Consistency
- Increased Productivity
- Reduced Rolling Scores
- Reduced Liner Fracturing
- Reduced Waste and Rejects
- Lower Cost of Ownership
- Guaranteed Improved Performance
