FIELD: construction engineering.
SUBSTANCE: invention is designed for use when repairing pipelines. New pipeline is wound inside existing pipeline from strip having special connectors to spiral trajectory with overlapping of adjacent edge parts of strip. Strip is fed axially in direction relative to axis of wound pipe and is passed between pair of drive rollers arranged inside said spiral trajectory. Shifting of strip is effected along outer side of guide rollers spaced over circumference and installed for creating a guide. Adjacent edge parts of strip are connected by forces acting onto shifted strip and counteracting forces created by tension in adjacent coil of strip.
EFFECT: enlarged operating range.
