Abstract:
1. A rotary packaging machine including: a pair of rotatably driven jaws to engage tubular bag material passing through the machine in a general direction of travel, the jaws being adapted to form transverse seals in the bag material to form discrete bags containing product; a drive member supporting each jaw, the drive members being driven in synchronism in opposite rotational directions; and an assembly to at least substantially prevent product being located between the jaws during sealing engagement with the tubular bag material, said assembly having a first operative configuration allowing product to pass along the bag material and a second operative configuration, said assembly when in said second configuration being engaged with the bag material to at least substantially prevent product being located between the jaws during sealing, said assembly including bag material deflecting and closing members mounted on said drive members so as to rotate therewith, which deflecting and closing members close said bag material and deflect the closed bag material laterally relative to said direction to at least substantially prevent product being located between the jaws when forming said seals.
