Sempre 15 and 30 – Compact Cold Glue Application Head – Flexible in Different Design Variants
The newest generation of “Sempre” cold glue heads stands for “Speed, Electro, Mini, Precise.” The Sempre 15 / 30 jetting head is suitable for dot, bead, and continuous application of dispersion adhesives. Thanks to their compact design, they can be easily and flexibly integrated, also for systems with limited space. With their precise adhesive application and high switching frequencies, they are ideal for applications in the graphical and converting industry.
Advantages of the Sempre 15 and 30 Cold Glue Heads – At a Glance
- Increased efficiency and productivity through fast start up and minimum maintenance effort
- Improved product quality through precise and clean adhesive application at high machine speeds
- Flexible integration thanks to a compact and narrow design
- Precise fine adjustment of the adhesive amount through integrate stroke adjustment
- Fast function tests thanks to an optional manual pushbutton, easy to retrofit
- Modular design with the following options: Product guide, trigger, brackets, CleanStart function, and adhesive application monitoring
Fast and Precise
The Sempre 15 and Sempre 30 ensure precise dot application with short distances even at high machine speeds. Furthermore, the optimized nozzle geometry ensures excellent cut-off behavior. The integrated stroke adjustment with simple scale is separated from the adhesive port and ensures precise and repeatable fine adjustment of the adhesive amount even under high pressure.
Durable and Efficient
The robust stainless steel design ensures a long service life and simplifies maintenance. Additionally, the vertical adhesive delivery from inlet to outlet reduces the mechanical stress on the adhesive within the application head. The optional CleanStart nozzle cover prevents adhesive drying at the nozzle outlet. This function supports a fast start up after an extended interruption and minimizes the cleaning effort. The application head can be purged near the head for testing or cleaning purposes using an optional manual pushbutton.
Different Design Variants
The cold glue application head is available in two design variants: the Sempre 15 is used for applications up to 15 bar and 24 VDC using PLC, while the Sempre 30 supports applications up to 30 bar and 6 VDC with overexcitation. Additional functions for supplementation and optimum adjustment to the respective customer requirements are available as options, for example, the product guide, a trigger, respective brackets, or adhesive application monitoring with iTac.
