FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to production of cold-roll-shaped sections from metal strips. Section axis main position is determined and arrangement of rolls relative to said main axis is adjusted. Note here that, in the case of symmetric section, said main axis is determined by straight line aligned with axis of symmetry of section in question, while, in the case of asymmetric section, it is determined by the line invariable in bending process. Rolls are arranged relative to section main axis with the help of adjustable spacing sleeves, for example, threaded sleeves.
EFFECT: simplified grooving of rolls.
