FIELD: technology of fire hose manufacture. SUBSTANCE: method includes manufacture of sheath from ethylene copolymer at temperature of 120-130 C at speed of 900-1000 m/h, and cohesion of sheath with woven cover is effected on steam line at110-120C for 501- min. Ethylene copolymer is used in form of copolymer of ethylene with vinylacetate or with acryl ether. EFFECT: reduced weight of hose running meter due to production of light and strong sheath with use ethylene copolymer for its production, higher productivity, improved operating conditions and prolonged service life. 2 cl, 2 tbl, 1 ex
