DEVICE TO APPLY ROLL INSULATION MATERIAL ONTO MANIFOLD PIPELINE Russian patent published in 2013 - IPC F16L58/02 F16L59/14 B08B9/23 

FIELD: machine building.

SUBSTANCE: device comprises a detachable rotor of circular cross section in the form of a squirrel cage with support rollers and double-sided fixed bobbins for fixation of roll insulation materials. Also it comprises an autonomously placed detachable unit of a drive equipped with support and cylindrical traction rollers, on which a mechanised drive is placed with a master sprocket. On one of rotor ends there are rigidly fixed sectors of sprockets that are evenly arranged or sprockets covered with a driving chain, which also covers the master sprocket of the mechanised drive. To synchronise axial displacement of the rotor and the unit of the drive, the end external ring of the rotor at the side of the drive is arranged between cylindrical traction rollers of the drive unit.

EFFECT: reduced labour costs, simplicity and ease of a structure, possibility to apply insulation onto pipelines of large diameters.
