Method of and apparatus for packaging a light-shielding photosensitive material roll, and apparatus for heating and supplying fluid

摘要

A packaging apparatus (10) has hot air supply mechanisms (64) disposed in association with light-shielding shrinkable films (26) wound on a rolled photosensitive material sheet (20), for ejecting hot air locally to the light-shielding shrinkable films (26), and a drive mechanism (66) for relatively rotating the hot air supply mechanisms (64) along an outer circumferential surface of the rolled photosensitive material sheet (20).
