Zusammenfassung:	FIELD: mining and using of brown coals. SUBSTANCE: briquette is placed between two layers of organic film, rolled with hot roll are upper and lower surfaces of briquette above film, and two layers upper and lower of organic film is rolled over side surfaces of briquette. All rolling operations are carried out at temperature of hot roller exceeding that of melting of organic film by 35-50 C to produce hermetic joint. EFFECT: higher strength of film and cut down cost of melted realization. 1 dwg
