FIELD: construction.

SUBSTANCE: accessory comprises a body made as assembled from sections, the number of which is determined by the diameter of the pipeline. Sections consist of rods and strainers. On rods there are levers fixed with handle steps for rotation of the accessory with the help of hands and feet around the pipeline, bobbin holders with mechanisms of tension force adjustment for an insulating tape and an anti-adhesive film. Bobbin holders are equipped with biaxial mechanisms for adjustment of their inclination angles and are installed in a cantilever manner in the front part of the device. The accessory is equipped with support rollers with mechanisms of changing of their installation angle made as capable of rolling of the applied coating. Sections may have hinged joints between each other with the possibility to match the accessory and the shape of the pipe cross section in the form of a deformed circle. Adjacent sections may have a common rod. The weight of the section does not exceed the weight permissible for lifting by one person. Braces are equipped with tensioning devices that comprise springy elements. The surface of support rollers is made of a soft material - polyurethane or rubber.
