FIELD: construction.

SUBSTANCE: roller of impact action with adjustable impact force includes a longitudinal axis of roller rotation with symmetry plane perpendicular to the longitudinal axis of rotation, and radial guide rods placed discretely and regularly in parallel planes, being rigidly fixed on the axial cylindrical element, besides, guide rods are placed inside impact elements and are equipped in the plane of guide rods with two cantilever ledges fixed on them with the possibility of temporary fixation of impact elements on them and free fall of impact elements down. At the same time the cantilever ledge is made as capable of changing its position on the guide rod, and the impact element is made as capable of changing its mass.

EFFECT: arrangement of paired cantilever ledges makes it possible to make both directions of roller rotation as working.
