Sempre 6 – Compact Cold Glue Application Head for Fast-Paced Applications

The electrically driven Sempre 6 jetting head is designed for contact-free application of low-viscosity dispersion adhesives. The durable application heads increase efficiency and productivity with their quick start up through the CleanStart function. The Sempre 6 cold glue head excels with its small installation dimensions and ensures improved product quality thanks to a precise adhesive application with clean cut-off behavior.

The newest generation of “Sempre” cold glue heads stands for „Speed, Electro, Mini, Precise.“ The Sempre 6 jetting head is suitable for dot, bead, and continuous application of dispersion adhesives. Thanks to its compact design, it can be easily and flexibly integrated, also for systems with limited space. With its precise adhesive application and high switching frequencies, it is ideal for applications in the graphical industry, as folding machines and mailers.

Advantages of the Sempre 6 Cold Glue Head – 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 and modularity
  • Precise fine adjustment of the adhesive amount through integrate stroke adjustment
  • No adhesive drying nozzle outlet through optional CleanStart function
  • Fast function tests thanks to an optional manual pushbutton, easy to retrofit

Fast and Precise

The Sempre 6 ensures 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 scale ensures precise and repeatable fine adjustment of the adhesive amount.

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.
