It has a guide to grip and receive, and a pair of front and rear folding projections that are installed at a distance approximately equal to the distance between the front and rear sides of the molded product, and advances from the side of the molded product held by the guide to the molded product side. The edge of one of the left and right edges of the individual paper sheets folded downward. A folding tool that folds in the left-right direction along the front and rear side surfaces and the lower surface of the molded product, and a molded product introduction end portion is positioned on the opposite side of the folding tool, and side walls are formed that are approximately equal in distance to the front and rear side surfaces of the molded product. A rail and a feeding means for feeding the molded product along the rail, and in the vicinity of the introduction end of the rail, among the left and right edge portions of the individual packaging folded along the lower surface of the molded product when the rail is introduced. A protrusion is provided to fold the other edge in the left-right direction along the front and rear side surfaces of the molded product, and the remaining folding portion that horizontally protrudes forward and backward is used to vertically fold along the front and rear side surfaces of the molded product. The notch is formed on the side wall.

[0007]

That is, in the apparatus of the present invention, the left and right ends of the individual packaging are first folded downward by passing the molded product on which the individual packaging is placed on the upper surface between the facing plates, and then by the folding tool. A rail having one of the left and right edges of the downwardly folded individual paper sheet folded in the left-right direction along the front and rear side surfaces and the lower surface of the molded product, and further having a predetermined protrusion and cutout portion While moving up, fold the other edge in the left-right direction along the front and rear side surfaces and the lower surface of the molded product, and the folding remaining part that horizontally projects forward and backward along these front and rear sides of the molded product. It is designed to be folded up and down. Therefore, according to this device, the four edge portions of the individual packaging eventually gather on the front and rear side surfaces of the molded product, and there is no folded portion on the upper and lower surfaces. For this reason, the folded portion does not protrude during stick packaging, and the upper and lower surfaces are clean, resulting in a beautiful appearance.

Next, embodiments of the present invention will be described in detail.
