Abstract
A method for forming annular bands to be used on rotors of electrodynamic machines for retaining windings on the rotors against centrifugal forces generated by rotation comprises winding a continuous single strand, ideally a single filament, of resinated reinforcing material onto a mandrel to form at least one, substantially continuous layer of the resinated reinforcing material along the mandrel, which layer of reinforcing material is cured to form a solidified cylindrical body, removed from the mandrel and circumferentially cut to form the annular bands. The annular bands are then pressed onto the rotor of an electrodynamic machine, with the resulting banded portions of the rotor preferably being resinated and cured to secure the bands to the rotor.
