たものである。(Prior Art) Conventionally, in a device for packaging this type of packaged article with a so-called half-folded film made of synthetic resin, the half-folded film is formed into a so-called U-shaped cross-sectional film by combining the upper and lower pieces and the joint portion thereof. In order to change the direction of flow of the film to a direction perpendicular to the direction of flow from the roll film mechanism, an opening mechanism is generally used, which consists of two plates in the shape of an upper and lower right-angled isosceles triangle. A belt conveyor for transporting the article to be packaged is arranged between these plate bodies, and the article is conveyed between the upper and lower pieces of the film having a U-shaped cross section. The film is fed out with force.

包装できないような欠点を有していた。(Problems to be Solved by the Invention) When a right triangular plate is used as the opening mechanism for a half-folded film and the film is sent as a U-shaped film as in the prior art, the film is It rubs against the edges of the cloth and generates a considerable amount of frictional resistance, heat and static electricity due to the friction, which of course causes scratches.
The charged film may cling to the plate, making its movement inconvenient, and the film may also stick to the vertices of the right triangle, causing local elongation and breakage. If the film is wet or the humidity is high, the film may be transferred in close contact with the belt conveyor and may not be sent to the destination properly, which has the drawback that the item to be packaged cannot be wrapped properly.
