(under subclass 430) Subject matter including a winding mechanism particularly adapted to wind elongated material onto a ball-shaped core.
(1) Note. In this subclass, winding is typically caused by driving an orbital guide, core support axle, or opposed core grippers while indexing either the guide or core to distribute the windings, which indexing may involve the use of a separate peripheral core-engaging driver.
