Document Type and Number:
Japanese Patent JP2009208396
Kind Code:
A
Abstract:
To produce a film with low occurrence of failures due to foreign matter by suppressing skin formation.
A dope reservoir apparatus 21 includes a dope reservoir tank 45 and a solvent gas supply section 46. The solvent gas supply section 46 generates a solvent gas 64a by evaporating a solvent 64. When a dope 38 is supplied to a casting die from the dope reservoir tank 45, the solvent gas 64a is supplied to the dope reservoir tank 45.
