Abstract: A method and apparatus for drawing tubular stock continuously and simultaneously through at least two successive drawing dies having mandrels located in the dies and within the tubular stock. The method comprises the steps of continuously pulling the tubular stock through the first one of the dies by a rotating capstan containing turns of the stock, the capstan simultaneously directing the stock to the second of one of the dies. From the second die, the stock is continuously pulled, the pulling of the stock continuously through the dies effecting a simultaneous reduction of the cross sectional area of the stock, with a single pass of the stock through the dies.

Abstract: An apparatus for paying off coiled tubular stock in a low inertia, smoothly flowing, continuous manner. The stock is pulled from a non-rotatable container and directed through an elongated, hollow guide structure having a large, open end adjacent the container, the guide structure gradually decreasing in cross sectional area to relatively small open end in the direction away from the container.
