Rotary Punching
Rotary punching stands for high cycle times and repeatability in the production of self-adhesive functional parts. Krückemeyer uses rotary punching processes efficiently for large-scale production runs and inline processes for adhesive solutions.
Rotatives Stanzen individuell
| Technique | Continuous punching using punch-cylinder tooling |
| Working width | up to 250 mm |
| Thickness | up to 2 mm |
| Tolerances | ±0.5 mm |
Rotary punching is the traditional punching technique: The material is continuously processed via punch cylinders and tooling. Within the working width, almost any contour can be realized flexibly.
| Technology | Register- and pinpoint-accurate stamping using camera technology |
| Working width | up to 600 mm |
| Tolerances | ±0.2 mm |
An advanced form of rotary stamping: The web speed is selectively accelerated or slowed using servo motors to stamp precisely at a defined point. Position sensing and control are camera-assisted.

Häufige Fragen zum Rotationsstanzen
During Punching of double-sided adhesive foils, the two-sided adhesive film materials on both sides are contour-cut into precisely defined shapes—matched exactly to the component geometry and the assembly process.
This solution is particularly advantageous when:
- two substrates are to be permanently joined
- precise fits in the serial production process are required
- thin, nearly invisible adhesive bonds are desired
- assembly times should be reduced and processes automated
Punched adhesive foils enable a clean, reproducible, and assembly-ready solution.
Almost all market-standard double-sided systems can be processed, e.g.,:
- Double-sided transfer adhesive films (without carrier)
- Carrier-based adhesive films (e.g., PET carrier)
- Thin high-performance films for permanent bonding
- Foam-based double-sided systems
- Custom-laminated multilayer composites
Additionally, adjustments such as adhesive formulation changes, one- or two-sided modifications, or the replacement of the protective cover (paper or film liner) are possible.
The achievable precision depends on the material structure and the overall thickness.
Through modern punching technology as well as optical quality control, tight dimensional tolerances and high repeatability are possible – even for intricate contours, internal cutouts, or functional openings.
Depending on the application process, a range of finishing options is available:
- Loose individual parts
- On rolls (for automatic feeding)
- On sheets
- With finger lift or peel-off aid
- With defined non-adhesive areas
- With modified protective cover
- As an installation-ready, multi-layer composite solution
The configuration is tailored precisely to the intended assembly process – manual, semi-automatic, or fully automatic.
Cost efficiency is determined, among other factors, by:
- Film type and total thickness
- Type of adhesive (e.g., for low-energy substrates)
- Contour complexity
- Tooling effort
- Quantity
- Additional processes such as laminating, liner changes, or application aids
Modular manufacturing processes enable both prototypes and production runs to be produced cost-effectively.
To enable accurate costing, the following information is helpful:
- Technical drawing or die-cut contour
- Material specification or substrate details
- Overall thickness and the desired adhesive type
- Requirements for temperature, UV, or chemical resistance
- Desired delivery form
- Project or annual quantity
- Information about the application process
The more precise the information, the more efficiently the optimal adhesive solution can be developed.
Samples and pre-series can be produced on short notice.
Thanks to flexible stamping and converting processes, rapid test samples are possible – ideal for validations, pilot runs, or process optimizations.
Innerhalb der Arbeitsbreite lassen sich nahezu alle 2D-Konturen umsetzen, zum Beispiel Klebepunkte, Klebestreifen, Klebepads, Sheets oder individuelle Klebestanzteile.
Hilfreich sind Materialtyp, Materialdicke, Rollenbreite, gewünschte Kontur, Stückzahl, Toleranzanforderung, Lieferform, Wickelrichtung und Informationen zum späteren Verarbeitungsprozess. Zusätzlich sollte angegeben werden, ob die Teile auf Träger bleiben, entgittert, gespendet oder automatisiert verarbeitet werden sollen.
Rotatives Stanzen ist weniger geeignet, wenn das Material zu dick, nicht wickelbar oder für die kontinuierliche Bahnverarbeitung ungeeignet ist. Auch sehr kleine Mengen, häufig wechselnde Geometrien oder besonders komplexe Materialaufbauten können eher für Flachbettstanzen, Laserschneiden oder eine andere Fertigungsvariante sprechen.
