<P>PROBLEM TO BE SOLVED: To provide a bag packaging machine capable of surely, compactly and simply creasing an end seal by folding the end seal with remaining heat after being sealed by heat-sealing by blowing air and cooling the end seal by the air. <P>SOLUTION: The end seal S3 likely to deform with the remaining heat immediately after being sealed by an end sealer 8 deforms by the pressure of air from an air nozzle 21, and the end seal S3 is folded together with a margin Fb of a tubular packaging material Ft. At the same time, the end seal S3 is cooled by the blown air. Since the end seal S3 is cooled while being folded to deform and kept deformed as it is, the end seal S3 is creased. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
