FIELD: mechanics.

SUBSTANCE: device comprises rope reduction roller cage arranged between rotor and drafting mechanism of rope laying machine. The latter revolves aligned with aforesaid rotor and has its rollers fitted at the angle corresponding to that of inclination of rope outer wire surface to roller axis. Roller cage represents two rotary mounting flanges. Separate roller blocks are locked between the latter, each roller block comprising roller holder pad attached on the flanges and furnished with cylindrical hole. Roller holder comprises roller and roller holder radial and angular adjustment mechanism. Aforesaid roller holder is mounted right in the pad hole to make radial and angular displacements relative to the pad. Mounting flanges have axial bores to allow unobstructed access to the rollers. Roller cage can be driven via belt, chain or toothed transmission from the shaft driven by rotor or self-contained drive and sideways of the cage.
