Abstract
A spinning-machine spindle rotatable about an axis has an upper cop-holding region and a lower nonsmooth reserve surface. The reserve surface is formed as a substantially uniform array of tiny pits separated by a raised continuous land extending as a continuous grid over the surface. Normally the pits are of pyramidal shape and the land lies substantially on a surface of revolution centered on the axis.
