PROBLEM TO BE SOLVED: To provide an effective method which has a purpose to stabilize the amt. of discharging an adhesive from a nozzle even when the amt. of the adhesive in a dispenser container is changed and can minimize the time needed for correction and can perform correction based on opening/closing time of a valve without using the value of pressure of a pressurized pneumatic pressure as a correcting means which is complicated and expensive. SOLUTION: The min. time for energization to a valve 19 is determined from the max. value of vol. of a pneumatic tank which a dispenser holds in common from a valve 19, the pressure to be attained and a synthesized effective crosssectional area of a pneumatic pressure circuit and timing when a nozzle of the dispenser 5 is elevated is determined by timing when a pressure sensor 25 detects atm. pressure. The time for correction is determined by dividing a difference between a known area indicated by a pressure diagram when the amt. of an adhesive in a dispenser 5 container is filled up and an area obtd. from the pressure diagram when the remaining amt. of the adhesive is decreased by the attained pressure and a new time for energization to the valve 19 is determined by adding the time for correction to the min. time.
