When packaging a roll product in which a belt-shaped sensitized material has been wound around a core with a light shielding sheet, the packaging apparatus is capable of forming an angle pleated portion of a gather-folded portion which covers a roll end surface with stability, and the package of roll product is capable of retaining the light shielding property and the moisture resistance while making the area of the sheet as small as possible. The gather-folding apparatus forms angle pleated portions on end surface wrapping material by means of both plate-shaped folding members which come into plane contact from outside of the end surface wrapping material and inter support arms which come into line-contact with the inner peripheral surface of the end surface wrapping material. This gather-folding apparatus forms, by means of both the surfaces of the plate-shaped folding members and the line of the inter support arm, two planes of folded planes sandwiching the line concerned. In this case, since these two planes of folded planes are formed with equal tension, the angle pleated portion can be formed with stability.

Packaging apparatus for roll product and package of roll product

A sheet cutting apparatus including an air removing mechanism and a sheet overlap preventing mechanism. The air removing mechanism includes an aligning device for pushing edges of a stack of sheets, which stack is placed on a table before being cut, towards a center of the stack to align the edges of the stack, and a cover member for covering the stack on the table such that the stack can be hermetically sealed, a pushing device for pushing the stack form above, and an evacuation device for removing air from a space between the table and the cover member to hermetically seal the space. The sheet overlap preventing mechanism is provided with a first restriction device for restricting a displacement of a plurality of stacks of cut sheets, with respect to a thickness direction of each of the stacks of cut sheets, and a second restriction device for restricting a displacement of portions to be cut off from the stacks of the cut sheets, with respect to a thickness direction of each of the portions to be cut off.
