FIELD: machine building.SUBSTANCE: method involves coiling of an insulation tape off a roll fixed on a bobbin holder. The tape is drawn through an accumulator and wound on the pipeline along a helical line with its fixation on the pipeline, with further growth of the tape when the tape of the used roll ends. The assembly includes a housing, two bobbin holders, a device for holding the tape down to the pipeline surface, a system of tape guiding and turning rolls, a heating unit and an accumulator. The accumulator represents a system of shafts installed parallel to the bobbin holders.EFFECT: possibility of being moved relative to each other so that the tape margin is provided on the pipeline surface at replacement of a roll.12 cl |
