FIELD: applicable in repair of mainlines. SUBSTANCE: the method provides for penetration of polymeric binder at speed of material towards the mandrel within 0.006 to 0.03 m/s and tension in glass cloth canvases within 250 to 700 kgf at temperatures of the heating and prepressing rolls with an after-hardening of binder by blank heat treatment. The device has platforms, carrying the tempering mechanisms with bobbin carriers inclined towards the mandrel. EFFECT: enhanced quality of manufacture of band spiral, etc strength. 10 cl, 32 dwg, 3 tbl
