Abstract
A packaging apparatus has hot air supply mechanisms disposed in association with light-shielding shrinkable films wound on a rolled photosensitive material sheet, for ejecting hot air locally to the light-shielding shrinkable films, and a drive mechanism for relatively rotating the hot air supply mechanisms along an outer circumferential surface of the rolled photosensitive material sheet.
Claims19
An apparatus for heating a gas with a heating body and supplying the heated gas to an object to be heated, comprising:
- a hollow outer casing having a gas inlet and a gas passage defined along an inner circumferential surface thereof;
- a hollow inner casing having a gas outlet and disposed in said outer casing, said hollow inner casing having a hollow space therein communicating with said gas passage;
- and
- a heating body disposed in said inner casing for heating a gas supplied through said gas passage into said inner casing;
- and
- a light-shielding chamber having a labyrinth gas passage defined therein and disposed in said gas outlet:
- the arrangement being such that said gas heated by said heating body flows out of said gas outlet and is supplied to said object to be heated.
An apparatus for heating a fluid with a heating body and supplying the heated fluid to an object to be heated, comprising:
- a hollow outer casing having a fluid inlet, a fluid outlet, and a fluid passage defined therein;
- a heating body disposed in said outer casing for heating a fluid supplied from said fluid inlet into said fluid passage;
- and
- a light-shielding chamber having a labyrinth fluid passage defined therein and disposed in said fluid outlet;
- the arrangement being such that said fluid heated by said heating body flows out of said light-shielding chamber and is supplied to said object to be heated.
An apparatus for heating a fluid with a heating body and supplying the heated fluid to an object to be heated, comprising:
- a hollow outer casing having a fluid inlet, a fluid outlet, and a fluid passage defined therein;
- a hollow inner casing disposed in said outer casing and having a hollow space therein communicating with said fluid passage;
- and
- a heating body disposed in said outer casing for heating a fluid supplied from said fluid inlet;
- and
- a light-shielding chamber having a labyrinth fluid passage defined therein and disposed in said fluid outlet;
- the arrangement being such that the fluid flows through said inner casing, said heating body, and said light-shielding chamber, and thereafter is discharged and supplied to said object to be heated.
