ABSTRACT OF THE DISCLOSURE
The present invention is a process for
drawing and forming a bright wire of a
predetermined diameter and cross-section, from
stock of a greater diameter. It includes the
steps of (a) continuously feeding said stock from
a supply spool through the process; (b)
mechanically removing scale from said stock; (c)
applying a coating of lubricant carrier to the
descaled stock; (d) applying drying air to the
stock with the lubricant carrier thereon; (e)
applying a lubricant to the carrier-coated stock;
(f) drawing the lubricated stock through one or
more pressure dies to decrease the diameter of
the stock down to the desired predetermined
diameter; (g) buffing the drawn stock with a
plurality of buffing wheels, said buffing wheels
being applied to the drawn stock at a plurality
of angles to the direction of travel of the stock
to produce bright wire; and, (h) coiling the
resulting bright wire into coils for subsequent
use. The process is continuous and the speed of
the stock is maintained by conventional drive
mechanisms to feed into the process and to coil
off the process at predetermined speeds. In one
embodiment, mechanical removal of scale includes
the following steps: (i) bending the stock in at
least three different directions over small
enough arcs to cause peeling of scale; (ii)
abrading of the stock to remove any remaining
scale; and, (iii) rinsing the stock to remove any
dust resulting from descaling. The present
invention also includes the apparatus for the
process.
