The foil heating system FHS is employed directly before slot nozzle adhesive application.
It enables the constant control of the foil temperature by warming up the wrapping material to a certain, predetermined temperature. The material is guided over a temperature-controlled heating plate, whereby its actual temperature is measured. The predetermined, desired temperature of the material is thereby found and kept constant, even throughout changes in the feed rate.
