Abstract
A latitudinal seal mechanism includes seal jaws , fixed cams cam followers a pair of partial cams , partial cam followers rotational shafts , coupling members and shaft support portions. The seal jaws are heated, and move circularly such that the seal jaws abut on and move away from tubular film. The fixed cams have shapes that correspond to locuses of movement of the seal jaws The cam followers support the seal jaws and move along the fixed cams The rotational shafts move the cam followers relatively about rotational centers of the rotational shafts The coupling members couple the rotational shafts and the cam followers The shaft support portions rotatably support the rotational shafts The partial cams have a shape that corresponds to a locus of movement of the pair of seal jaws when the pair of seal jaws holds the tubular packaging films. The partial cams make the pair of seal jaws press against each other with the partial cam followers therebetween. The partial cam followers are supported by the pair of seal jaws The partial cam followers engage the corresponding partial cams when the pair of seal jaws holds the tubular packaging film therebetween.
