FK IT - precise, efficient, and flexible adhesive coating

The hot melt coating heads of the FK IT series are designed for intermittent and continuous coating of thermoplastic adhesives. Thanks to simple and cost-effective mask technology, they can be flexibly adjusted for the respective application.

The FK IT coating heads are characterized by a precise adhesive tear-off behavior and coating weight, also with high production speeds and fast switching times. The coating heads are mainly used in processes of the graphical and packaging material industry, as well as in other areas.

Advantages of the FK IT coating head – at a glance
  • Precise tear-off behavior due to double-acting solenoid valve and negatively closing jetting element
  • Flexible, fast, and cost-effective format change using mask technology
  • Easy integration thanks to compact design and connection from top
  • Constant temperature control up to the coating nozzle based on the special design ensures consistent adhesive quality and constant coating weight
  • No nozzle blockages thanks to integrated filter
  • Operator safety through optional CoolTouch insulation
  • Coating nozzle can be flexibly rotated by 180° in or against the operating direction
Easy integration and safe operation

Thanks to compact design and adhesive, compressed air and supply voltage connection from above, the coating heads of the FK IT series can be easily integrated into an existing system. The application heads are used for surface coating on continuous material sheets as well as for surface coating on sheet feed in folding machines. In the case of sheet feed, the application head can be used in connection with the feed roller, as well as the specifically developed backing plate. Thanks to heat-resistant CoolTouch insulation, the FK IT helps with increasing operational safety.

Backing plate
Flexible in the application for precise and high-quality surface coating

The coating heads are double-acting with the jetting element closing negatively. This functionality ensures precise adhesive application and tear-off from start to finish. The application pattern can be flexibly adjusted using different mask shapes and thicknesses. The mask technology of the coating head simplifies the format change, increases reproducibility, and supports a cost-effective and flexible gluing process. Furthermore, the coating nozzle can be rotated by 180° for easy switching of the application in or against the operating direction.
