FK-IT Coating Head

FK-IT Coating Head

Designed for intermittent and continuous coating with flexibility to adjust coating width

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 behaviour 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.

The application heads are used for surface coating on continuous material sheets as well as for surface coating on sheet feed in folding machines. 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.
