BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for wrapping, for example, bound magazines and sheets, and a mechanism for folding both sides of a wrapping sheet when wrapping using this apparatus.

[0002]

2. Description of the Related Art This type of packaging apparatus generally uses roll paper as a packaging paper, cuts the roll paper to a predetermined length, and then sequentially folds and wraps the paper.

[0003]

Therefore, in the packaging apparatus using the roll paper described above, it is necessary to change to a roll paper having a different width each time the size of the packaged article is changed, and the roll after cutting is cut. Since the paper has a curl, the packaging work may not be performed smoothly. Further, changing the roll paper is a heavy work because the roll paper has a large weight, and there is a safety problem.

The present invention has been made in view of the problems of the above-described conventional packaging device, and can easily cope with the change of the size of the object to be packaged and can perform a smooth packaging operation. An object of the present invention is to provide a device and a folding mechanism that constitutes the packaging device.
