FIELD: manufacture of insulating tapes used for protection of articles against corrosion such as oil pipe lines, gas lines, sewage lines. SUBSTANCE: proposed method includes application of insulating layer on flexible tape followed by calibration of thickness of tape; then tape is cooled, coated with anti-adhesive material which is rolled to insulating layer and relieved from residual deformation; procedure is completed by forming roll. Static electricity is removed from anti-adhesive layer. Flexible tape is subjected to tractive force during entire technological path. Plant proposed for manufacture of insulating tapes includes various units for performing the said operations. Proposed method excludes unauthorized deformation of insulating tape in the course of manufacture. EFFECT: enhanced efficiency and reliability. 4 cl, 4 dwg
