FIELD: rolled stock production.
SUBSTANCE: method comprises steps of measuring tensioning efforts successively along width of band when it passes through manufacturing line; summing measured efforts for forming function of their total effort. Total effort function along width of band is used for determining distribution function of tensioning effort for determining band planeness. Apparatus for measuring band planeness includes at least one pickup arranged along width of band, connected to computing unit. Said computing unit is made with possibility of calculating tensioning stresses along width of band according to tensioning efforts acting upon band. Said pickup is placed by inclination angle relative to band motion direction.
EFFECT: enhanced accuracy of measuring planeness.
