ABSTRACT:
A web roll wrapping apparatus comprises a shaft for holding a core of a photographic film roll, a folding unit for folding a protruding part of a light-shielding sheet wound around the photographic film roll, a heating unit for heat-sealing the folded part of the sheet, and a cooling unit for cooling the heat-sealed part of the sheet. The photographic film roll is rotated around the shaft, and the protruding part of the light-shielding sheet is folded down onto an end face of the photographic film roll by the folding unit. When passing the heating unit, the folded part is heat-sealed by a heating roller, and when passing the cooling unit, the heat-sealed part is cooled by a cooling roller to be prevented from loosening.
