FIELD: the invention refers to manufacturing of fire-proof covering and may be used in chemical industry, construction, mechanical engineering and other fields of industry and vital activity of man there where insulated, light and fire-proof coverings are applied.
SUBSTANCE: the mode is fulfilled in the following manner. The polymer film is preliminary perforated. Then a plastic fire-proof compound is put on with possibility of polymerization. After that the film is winded in a roll with following exposure in the roll The winding into the roll is executed with packing an additional non perforated polymer film between the layers of covering. At that the exposure in the roll is carried during the whole period of time corresponding 50-80% of duration of full polymerization.
EFFECT: high productivity of the mode and its technological effectiveness with relatively not high labor-consuming character.
