| titleOfInvention | Solution casting method and apparatus |
| abstract | In a solution casting apparatus, polymer dope containing cellulose ester and solvent is cast to form cellulose ester film continuously. A filtration device has a precoat of a filter aid deposited on a filter screen, for filtering polymer dope to be cast. A washer washes the filtration device after discontinuing supply of the polymer dope to the filtration device. A filter regenerating device deposits a precoat of the filter aid in the washed filtration device by use of precoat solution containing the filter aid, the polymer dope and solvent. A drain line drains the precoat solution from the filtration device after depositing the precoat. The filtration device is charged with solvent saturated gas upon draining. A valve mechanism changes over plural filtration devices, to manage the filtration device among the filtration devices in the washer, the filter regenerating device and the drain line. |
