Roller die wire drawing device having a plurality of roller die units
 The invention is related to a wire drawing device having a plurality of roller die units. Each unit contains two opposing grooved rollers which are respectively mounted in bearing frames which are connected to one another in an opposing fashion by threaded shanks. The shanks are rotatable and function to regulate the distance between the rollers. Each unit is housed in a square frame. The square frames are structured and dimensioned such that they can be serially aligned whereby the radial planes of each adjacent set of grooved rollers are perpendicular to one another thus allowing the distance between adjacent rollers to be less than the diameter of the rollers.
