METHOD FOR PACKAGING SHADING PHOTOSENSITIVE MATERIAL ROLL AND ITS APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce the whole size of the apparatus and simplifying it and also to carry out packaging highly precisely at low cost. SOLUTION: The packaging machine 10 comprising a hot air supplying mechanism 64 and a driving mechanism 66 for rotating the hot air supplying mechanism 64 relatively along the periphery of the roll, the hot blast supplying mechanism 64 which is arranged corresponding to a shading shrink film 26 wound by the photosensitive material roll 20 and which ejects locally a hot air to the shading shrink film 26.
