FIELD: machine engineering, manufacture of special articles of wire.

SUBSTANCE: device includes housing having at least two parting portions; attachment for fixing blank having power drive and secured to end part of housing; mechanism for rotating device together with blank by means of drive having brake. In order to work elongated complex-configuration articles, each portion of housing is made in the form of hollow semi-cylinder whose one surface is cut in the form of semi-pinion for forming hollow cylinder (after closing on end surfaces of housing) at least with one lateral toothed surface whose teeth are engaged with pinion of mechanism for rotating device at closing portions of housing. Mechanism for rotating device together with blank is in the form of system of rolling around rollers mounted in horizontal axles arranged outside and inside housing. On end surface of one semi-cylinder there are pins coaxially entering reciprocal openings of other semi-cylinder for centering both semi-cylinders of housing after their mutual closing. Power drive for fixing blank is provided with locking unit engaging with one semi-pinion of housing of device.
