PROBLEM TO BE SOLVED: To easily perform an adjusting operation to support an openable tray delivery part in a horizontal posture and reduce a danger that the delivery part is closed violently. SOLUTION: The packaging machine includes a tray delivery part 4 which is turnable, about a rotation fulcrum, on the side of a width direction piece, between a closing point where the upper portion of a film feed part is closed and an opening point where the upper portion of the film feed part is opened and a supporting frame 60 which supports the delivery part 4 from blow at the closing point. The frame 60 is formed from a pair of side frames 61, a bar-like first receiving member 62, and a pair of second receiving members 63. The member 62 supports a receiving end of the part 4 provided between both the frames 61 from below. Each member 63 has a vertically retractable adjusting screw 66 and the screw 66 is mounted to each of the frames 61 in such a manner that the height of the screw can be adjusted to support a delivery end of the part 4 from below. Thus torsional deformations of the part 4 at the closing point can be prevented. |
