PURPOSE:To obtain exactly the final weight to be fed out in conformity with setting by detecting the changing feed-out weight with a weight detector in real time, calculating the rate of increase and predicting the feed-out weight after the prescribed time always after the detection from the calculated rate and the prescribed time. CONSTITUTION:The changing feed-out weight is detected in real time by a weight detector 13 and the rate of the increase thereof is calculated. The feed- out weight after the prescribed time always after the detection is predicted from said rate of the increase and after-flow time. The point of the time when the predicted value attains the final feed-out weight which is set as a target is determined as the timing for starting the after-flow and a pressurizing valve 4 is closed then a discharge valve 5 is opened to obtain exactly the target final feed- out weight in conformity with the setting. |
