FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used for continuous banding of variable-cross-section billets. Control over bender is effected that comprises some drive rolls and PC-aided control means connected with distance metre. Note here that the distance of long billet at one point located after row of rolls for bending at subsequent moments is measured. Radius of curvature of every bent section is calculated to compare calculated radius of curvature with required one and to define the difference there between. Change in position for roll to be made for elimination of said difference is calculated. The roll is forced to sais calculated position.
EFFECT: expanded performances, higher efficiency.
