The present invention relates to the use of vacuum packaging and vacuum packaging techniques. Embodiments of the present invention include bales and packages comprising a sealed chamber having an internal volume at a pressure less than ambient atmospheric pressure. In alternate embodiments of the present invention, the internal volume of the package comprises a bulk material, a bulk fiber material, fibers or fibrous materials. Also disclosed are methods for packaging, packaging systems and apparatus for packaging.

A numerically controlled milling machine is used to mill the surface of a coined spinnerette after punching and before broaching the holes in the spinnerette. A probe is mounted on the milling machine to obtain data points on the bumpy surface of the coined spinnerette. The low points in predetermined areas off of the protuberances on the bumpy surface of the coined spinnerette are detected. Splines connecting the low points in, e.g., concentric rings if the holes in the finished spinnerette will be in rings, are used to generate a representation of the finished surface. A spiral tool path is obtained using the representation of the finished surface and G-codes are generated to control the milling machine to move a tool along the tool path. After the coined spinnerette has been milled, conventional finishing, including broaching is performed.
