[Category : - MECHANICAL ENGINEERING- OTHER- DESIGN PATENTS]
[Viewed 1347 times]

The present invention relates generally to a high speed winding machine with angular rotary spindle, The present invention also relates generally to winding machines for winding a cable, and more particularly winding wire at higher speeds without the use, for example, of a reciprocating traverse. The high speed winding machine, primarily comprises of four major systems, namely, a frame assembly, a rotating traverse assembly, an angular spindle assembly, and a spindle drive motor assembly, having a spindle indexing system.

A method of winding a wire or cable in a figure-8 pattern upon a mandrel by rotating the mandrel and winding the wire or cable. Many types of wire and cable are sold in spool-less packages. The term “package” is a term of art which refers to the coil of wire itself that is wound in a figure 8 to hold itself together. This type of package includes a plurality of windings with each winding crossing itself to form a figure 8. The crossovers of successive windings are angularly displaced and progress around the circumference of the package. The crossovers do not progress a full 360° around the coil so that a radial opening is formed extending to the center of the package. The configuration of the package permits the wire to be extracted or paid out without kinking or twisting. The twist-less payout is due to the manner in which the wire is wound. The twist in each half of the figure 8 winding is offset by the opposite twist of the winding in the other half. Thus, there would be no substantial twisting of the wire as it is paid out.
