Abstract
A method and apparatus for the high speed reshaping of round wire as it exits a drawing machine, but prior to its being collected on a bobbin or a stempack. The shape imparted to individual wires is such that as the preshaped wires are applied to a core by a stranding machine, a cable results in which there is substantially no interstitial space between the wires which add excessive bulk.
Claims14
Passing an electrical wire through a reshaping means for reshaping a round electrical wire after said round wire has been drawn down in a drawing machine from larger diameter stock, but before said wire has been collected at the end of a drawing machine, comprising:
- guiding said conductor, with a guide means for guiding, after it exits said drawing machine, into a reshaping means, said reshaping means comprising a pair of opposed reforming means and being juxtaposed between said drawing machine and a pulling means;
- reshaping said conductor in said reshaping means, said reshaping means being juxtaposed between said drawing machine and a pulling means;
- pulling said conductor through said reshaping means, said pulling means positioned between said reshaping means and a collecting means;
- and
- collecting said conductor after it has been reshaped, said collecting means being positioned after said pulling means.
Apparatus for reshaping a round electrical wire after said round wire has been drawn down in a drawing machine from larger diameter stock, but before said wire has been collected at the end of a drawing machine, comprising:
- a reshaping means for reshaping said conductor, said reshaping means comprising a first and second wheel, said wheels being singly, individually, and rotatably mounted respectively on a first and second axle, the axis of said first axle being parallel to the axis of said second axle, and the axis of both axles positioned at right angles to the axis of movement of said round wire, and each wheel having a groove machined into its periphery, said groove forming a portion of the reshaped cross sectional configuration of said reshaped wire, and the periphery of each wheel being tangent to the periphery of the other wheel at a point, said point being substantially aligned with the axis of movement of said electrical wire, and the cross sectional area of said reshaped wire being controlled by a trim adjustment and being attached to said drawing machine and juxtaposed between said drawing machine and a collecting means;
- a guide means positioned at the entry end of said reshaping means for guiding said round wire into said reshaping means after said round wire leaves the exit end of said drawing machine;
- a pulling means positioned at the exit end of said reshaping means for pulling said wire through said reshaping means;
- and
- a collection means for collecting said wire after said wire has been reshaped, said means being positioned after said pulling means.
