ABSTRACT:
An apparatus for winding saddle shaped coils particularly useful as deflection coils for cathode ray tubes. The apparatus can handle single or multiple strands of wire depending upon the coil design, and includes a winding pattern generator (26) connected to a winding head (28) which feeds the wire into a suitably configured mould. The winding pattern generator directs the winding head in sequential arcuate and longitudinal directions and does not stretch the wire as turns are made in the coil. This stretching or "necking down" of the wire, which occurred in prior art machines of the lathe type, caused varying electrical characteristics in the coils which presented a problem to the ultimate users.
