PROBLEM TO BE SOLVED: To enable a bag to be sealed positively from the beginning to be formed even in the restarting after the stop by operating vertical sealing means for a predetermined period of time at the time of outputting a first ejection demand signal to a measuring device, and operation transfer and lateral sealing means after the wait of an ejection completion signal. SOLUTION: When an ejection demand signal of an article to be sealed is outputted to a measuring device 1 from ejection demand signal means 11, a signal is outputted from electromagnetic valve actuation signal output means 15, so that an electromagnetic valve 65 is actuated so as to make a vertical sealing mechanism 6 operate with the result that a vertical sheet belt 66 is brought in press contact with the vertical alignment of packaging material (f) so as to effect a required seal. On the other hand, with respect to the actuation of a pull-down belt 51 or lateral sealing jaw 71, after the wait of an ejection completion signal outputted from the measuring device 1, a signal is outputted from ejection completion signal inputting means 12 via a timer 13, and each motor 52, 72 of a pull-down mechanism 5 and lateral sealing mechanism 7 is driven to be controlled for its predetermined packaging operation. |
