Abstract:
A package of a role product, which covers an outer peripheral surface of a roll made of a belt-shaped photosensitive film material wound around a cylindrical core in a roll shape with a sheet having larger width than the width of the roll to gather-fold a cylindrical portion of the sheet protruding outwardly from an end surface of the roll by a gather-folding apparatus along the roll end surface, and which a bushing member is pressed into the core to thereby fit an inner peripheral edge of a gather-folded portion by the core and the bushing member,wherein ridges of crest folded portions of a plurality of angle pleated portions which form the gather-folded portion are formed to be longer than ridges of trough folded portions; when gather-folding is performed, each of the angle pleated portions lies on top of the angle pleated portion adjacent thereto; and the ridges of the crest folded portions face a center of the roll product.
