FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to making of L-shape components from metal sheet. Sheet blank is arranged between female die, male die and bending press. Vertical wall sections and flange sections are formed at sliding of at least a part of sheet blank over the part of female die corresponding to top sheet section. Note here that said both sections are formed at position whereat at least the part of sheet blank is squeezed by male die or at position whereat male die is brought in contact with sheet blank.
EFFECT: higher tensile strength.
