ABSTRACT:
A solvent recovery apparatus, in particular, for manufacturing apparatus of web-like materials, preferably sound tapes and video tapes, is equipped with a heat exchanger which returns a preferably larger portion of a gas prepurified of solvents downstream of a solvent separator via a line and heats it against the flow of the solvent-charged gas from the drier in order to return the preheated larger portion into the drier; a preferably smaller portion of the prepurified gas is freed from remaining solvent residues downstream of the solvent separator in a cryogenic apparatus, supplemented with a thereby vaporized part of inert gas in order to subsequently be supplied to transfer chambers of the drier to produce there a positive gas flow directed both into the drier and to the outside. The proposed method can be carried out on the apparatus describe.
