FIELD: civil and industrial construction, particularly apparatus or processes for treating or working non-hardened concrete articles, particularly for reshaping the surface, namely smoothing, roughening, corrugating, making screw-threads.
SUBSTANCE: multiroll working tool comprises four rolls having the same diameters and forming single working surface. The rolls may rotate about common axis with different speeds by means of planetary gears.
EFFECT: increased quality along smoothing leading edge, working surface wear uniformity, simplified worn roll displacement, decreased costs of working surface production and usage.
