FIELD: plastic working of metals, namely apparatuses for horizontal cold bending of shaped metal.

SUBSTANCE: apparatus is designed for producing from metallic rods shaped bent blanks having similar bent fragments repeating along the whole length of blank and having sign-variable bent portions for making openwork products such as guards, gates, window grates and so on at condition of small-batch production and restricted production areas. High quality of bent blank is provided due to additional reduction of bent fragment by means of mechanism for fixing blank.
