Abstract
Stators are produced by advancing stator workpieces successively to a plurality of work stations. The stators are mounted in holders which each comprises a pair of downwardly depending legs resting on a pair of horizontally spaced conveyor belts. The belts are continuously driven to advance the holders to the work stations. At each station the holder is restrained from movement (e.g., by being lifted off the belts) while the belts continue to be driven. At a winding station, upper and lower winding forms are advanced toward a stator workpiece, the lower form passing between said belts and legs.
