<P>PROBLEM TO BE SOLVED: To effectively remove water drops adhering to a bag mouth inner surface of a wrapping bag storing contents therein. <P>SOLUTION: When the wrapping bag 20 conveyed with a supporting tool 13 reaches and stops at a heating station, a heating bar 31 having a vertical width approaches relatively from both sides of a bag mouth of the wrapping bag 20, and narrows the bag mouth to the extent of leaving a venting gap 50 in the bag mouth and heats the bag mouth. In this case, since air passes freely through the venting gap 50, a water film adhering to the venting gap receives heat from the heating bar 31 provided with a heater 51 and passes through the venting gap 50 so as to be evaporated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
