ABSTRACT:
Apparatus and method for reducing wire and other elongated components in section by passing them through a reservoir containing a substance which will act as a lubricating and pressurizing medium and then, surrounded by the medium but without solid-to-solid contact, through a cavity formed in two parts which meet at a step where the radius diminishes sharply. The least section of the cavity exceeds the section of the unreduced component. The reservoir may be provided with a heater whereby the medium may be melted after being introduced to the reservoir in solid form. The component may be either drawn or thrust, and may undergo a change in shape as well as in the size of its section as it is reduced.
