Abstract
Multiple elongated products are formed simultaneously from a single workpiece, coated with a lubricant or other fluent material, by forcing the workpiece against and through a die having multiple apertures. The apertures are so arrayed as to permit a relatively free flow of the coating material to each of the die apertures, including one or more generally central apertures. Preferred aperture configurations include straight line arrays and shallow curves, such as shallow "S"-shaped curves. The workpiece may advantageously correspond in general shape to that of the configuration of apertures in the die through which it is to be forced.

Apparatus for deforming a lubricant-coated, metallic workpiece to produce simultaneously a plurality of elongated, metallic products, said apparatus comprising:
- a die having a plurality of discrete apertures extending in parallel therethrough, including at least one generally central aperture and a plurality of additional apertures, said at least one generally central aperture being located closer to a center of the die than is each of said additional apertures, said plurality of discrete apertures being arrayed along an open-ended curve selected to promote a free flow of the lubricant coating on the metallic workpiece both to said at least one generally central aperture and to said additional apertures upon a forcing of said metallic workpiece against and through the die, while simultaneously permitting numerous apertures to be included in the array of apertures so as to reduce the pressure required for said forcing;
- and
- means for forcing the lubricant-coated, metallic workpiece against said die with sufficient pressure to cause different lubricant-coated portions of the metallic workpiece to pass simultaneously through said at least one generally central aperture and said additional apertures while applying the lubricant coating to each of said generally central and additional apertures, such that a plurality of elongated, metallic products is produced.
A method of deforming a lubricant-coated, metallic workpiece to produce simultaneously a plurality of elongated, metallic products, said method comprising:
- a. aligning the lubricant-coated, metallic workpiece with a die having a die body which includes a plurality of discrete apertures extending therethrough, said discrete apertures being arrayed along an open-ended curve selected to promote a free flow of the lubricant coating on the metallic workpiece to all of said discrete apertures upon a forcing of said metallic workpiece against and through the die, while simultaneously permitting numerous apertures to be included in the array of apertures so as to reduce the pressure required for said forcing;
- and
- b. forcing the lubricant-coated, metallic workpiece against, and through the plurality of apertures of, said die.

- a. aligning the lubricant-coated, metallic workpiece with a die having a die body which includes a plurality of discrete apertures extending therethrough, said discrete apertures being arrayed in a general "S"-shaped configuration selected to promote a free flow of the lubricant coating on the metallic workpiece to all of said discrete apertures upon a forcing of said metallic workpiece against and through the die, while simultaneously permitting numerous apertures to be included in the array of apertures so as to reduce the pressure required for said forcing;
- and
- b. forcing the lubricant-coated, metallic workpiece against, and through the apertures of, said die.
