PRODUCT ADHERENCE PREVENTING MECHANISM FOR THREE-SIDED SEALING MACHINE, THREE-SIDED SEALING MACHINE EQUIPPED WITH THE MECHANISM, AND BAG-MAKING METHOD

PROBLEM TO BE SOLVED: To make a quick an continuous packaging work possible without fusing of a film and to make a constant attendance by an operator unnecessary. SOLUTION: A product adherence preventing mechanism is for a three-sided sealing machine which forms a film into a cylindrical structure with a heat sealing applied to parts overlapping each other in the vertical direction and makes up the film into a bag with the heat sealing applied to the bottom part of the cylindrical structure with a traverse sealer and also applies the heat sealing to the upper opening with the traverse sealer after an article to be packaged is inserted from the upper opening and completes packaging with the heat sealing applied to the three sides, and the preventing mechanism is a pair of devices positioned respectively at the underside of a pair of opposite traverse sealers and fixed to the three-sided sealing machine main body on a position whereto a packaged product adherent to one of the paired sealers moving in the direction of separating from each other after the sealing is made at the upper part comes into collision. The three-sided sealing machine is such a one which is equipped with the above-mentioned preventing mechanism, and the packaging method is such a one which employs the above-mentioned sealing machine.
