FIELD: process engineering.
SUBSTANCE: rolls are arranged to de displaced axially by drives (4, 104, 204). Note here that the latter comprises, at least, one hydraulic cylinder (5, 6, 105, 106, 205) to control axial displacement of rolls. Proposed system comprises means (11, 12, 13, 14) to allow displacement of roll bearing holders (15, 16, 17, 18) perpendicular to axial direction A and in axial direction by rotary motion. Hydraulic cylinder is arranged in frame mounted spatially fixed or moving coupled with device elements.
EFFECT: simplified design.
