PROBLEM TO BE SOLVED: To shorten the time required for raising the temperature of the adhesive in an adhesive dispenser to a set temperature from a cooled state and to prevent the temperature of the adhesive from exceeding an allowable temperature range (set temperature±allowable temperature change quantity) to overshoot. SOLUTION: In a case that the temperature of the adhesive detected by an adhesive temperature sensor is separated from the set temperature by a predetermined temperature or above in a system for regulating the temperature of the adhesive by allowing temperature regulating air to flow to the temperature regulating passages 22 and 23 formed to the adhesive dispenser 11, a "quick temperature regulating mode" for increasing the temperature difference between the temperature of air on an inlet side and the set temperature to quickly change the temperature of the adhesive to the set temperature is selected. In a case that the temperature of the adhesive detected by the adhesive temperature sensor enters a predetermined temperature range from the set temperature, a "temperature holding mode" for regulating the temperature of air on the inlet side detected by the air temperature sensor on the inlet side to the set temperature or the vicinity thereof is selected.
