Key Features of the SIAT Nastro-SB R-Series
Automatic Random Carton Adjustment
One of the key advantages of the Nastro-SB R-Series is its ability to accommodate different carton dimensions without manual adjustment between boxes.
This makes the machine particularly useful for businesses packing multiple products, SKUs or carton formats on the same production line. Operators can load cartons of different sizes, while the machine automatically adjusts to the carton format.
Top and Bottom Case Sealing
The Nastro-SB R-Series seals both the top and bottom flaps of cardboard cartons, providing a consistent and secure tape seal as cartons move through the machine.
This can help replace repetitive manual carton sealing with a more controlled and consistent process.
Patented Variable-Speed Technology
The R-Series incorporates patented variable-speed technology, allowing the machine to adjust its operating speed according to the packaging application.
The variable-speed function can increase machine capacity by up to 70% compared with standard operating conditions.
On-Board Logic
The Nastro-SB R-Series incorporates on-board logic, providing operators with machine information and diagnostic capabilities through the control system.
The system can provide information relating to machine operation, including production performance and consumable usage, helping operators and maintenance teams identify issues and optimise machine performance.
Energy-Saving Functionality
An energy-saving device is included as standard. The machine can also stop motors and conveyors after a defined period when cartons are not detected, helping reduce unnecessary energy consumption during operation.
Quick-Release Taping Head
The R-Series features SIAT’s Quick Release Taping Head system, allowing the top and bottom taping heads to be removed without tools.
This can simplify maintenance, cleaning and tape-head servicing, helping reduce downtime.
Robust Industrial Construction
The Nastro-SB R-Series is designed for demanding packaging environments, incorporating reinforced conveyor belts and machine columns to provide stability during operation.
The range also incorporates industrial-grade electrical and pneumatic components designed for reliable long-term operation.
Optional IoT Connectivity
The Nastro-SB R-Series can be equipped with an IoT module connected to SIAT’s Optirun platform. This provides the opportunity to monitor machine performance, productivity, operating time and tape consumption, giving production and maintenance teams greater visibility over packaging operations.
Why Choose the SIAT Nastro-SB R-Series?
Ideal for Multiple Carton Sizes
If your packaging operation handles cartons of different dimensions, manually adjusting a conventional case sealer can create delays and additional operator workload.
The Nastro-SB R-Series is designed specifically for random carton applications, automatically adapting to different box sizes as they enter the machine.
Improve Packaging Productivity
Automating carton sealing can reduce the time and labour required to manually tape boxes. The R-Series combines automatic carton adjustment with variable-speed technology to support efficient end-of-line packaging.
Improve Sealing Consistency
Consistent tape application helps ensure cartons are securely closed before storage, handling and transportation.
The Nastro-SB R-Series provides controlled top-and-bottom sealing to help maintain consistent carton presentation and sealing quality.
Designed for Growing Operations
The range includes different configurations to accommodate different carton widths, making it possible to select a machine that matches current production requirements while allowing room for future packaging needs.
Integrate with Your Packaging Line
The Nastro-SB R-Series can form part of a broader automated end-of-line system incorporating equipment such as fillers, cappers, labellers, conveyors, case erectors, conveyors, case packers and pallet wrappers.
Packserv can help manufacturers assess their complete packaging process and identify opportunities for further automation.

SIAT Nastro-SB R-Series Models
The Nastro-SB R-Series is available in different configurations to accommodate different carton widths.
- Nastro-SB R5
The R5 configuration is designed for small to medium carton applications.
Current SIAT specifications provide carton widths from approximately 150 to 500 mm, depending on the configuration, with height ranges extending from approximately 50 or 90 mm up to 500 mm.
- Nastro-SB R6
The R6 provides a wider carton-processing capability, with configurations supporting carton widths up to approximately 650 mm and heights up to approximately 650 mm.
- Nastro-SB R8
The R8 is the larger-format option in the range, supporting carton widths up to approximately 800 mm and heights up to approximately 800 mm, depending on configuration.
The S and L configurations provide different minimum carton dimensions, allowing the machine to be selected according to the carton formats being processed.
