摘要
When packaging a roll product (12) in which a belt-shaped sensitized material has been wound around a core (32) with a light shielding sheet (16), the packaging apparatus is capable of forming an angle pleated portion (19) of a gather-folded portion (28) which covers a roll end surface (13) with stability, and the package of roll product (12) is capable of retaining the light shielding property and the moisture resistance while making the area of the sheet (16) as small as possible. The gather-folding apparatus (40) forms angle pleated portions (19) on end surface wrapping material (18) by means of both plate-shaped folding members (70) which come into plane contact from outside of the end surface wrapping material (18) and inter support arms (80) which come into line-contact with the inner peripheral surface of the end surface wrapping material (18). This gather-folding apparatus (40) forms, by means of both the surfaces of the plate-shaped folding members (70) and the line of the inter support arm (80), two planes of folded planes (19A) sandwiching the line concerned. In this case, since these two planes of folded planes (19A) are formed with equal tension, the angle pleated portion (19) can be formed with stability. IMAGE
