ABSTRACT:
A packing apparatus of the present invention includes an original roll having a packing material sheet that contains a middle portion in a width direction, and a triangular plate having a triangular plane, and oblique sides connecting the base and the vertex, the material sheet is folded in two at the width-direction middle portion by the vertex with a tension applied to the material sheet, to form a bending portion, an overlapped portion containing sides in a width direction, and a triangular open space. Furthermore, the packing apparatus includes a pair of drawing rolls for drawing out the material sheet and, and a fusing and cutting device for fusing and cutting the overlapped portion to consecutively form a packing bag having the bending portion as a bottom and the open space as an insertion aperture for a packed member.
