ABSTRACT:
A method and apparatus for precision winding of coils on bobbins. Ideal positions for all portions of wire on the bobbin are predetermined on the basis of a planned winding profile taking into account number of turns, wire size and bobbin dimensions. Then incremental control of traverse, simultaneously with spin of a fly head winder, relative to the bobbin is utilized to put the wire down on the bobbin at the ideal positions independently of the lay of prelaid turns. The control is preferably done through a computer whose memory contains essential data on the winding profile. The computer is programmed to read feedback signals on instantaneous traverse and spin and provide control signals to cause the winder to duplicate the coil winding profile.
