Abstract

Apparatus for precision level winding of coils. The apparatus is particularly adapted for precision level winding of a continuous set of coils, in which each of the coils in the set may have a number of turns differently from each of the other coils in the set and may be of a length and pitch different from each of the other coils in the set. The apparatus includes means for automatically applying coils of wire to a coil holder member which has a plurality of aligned substantially coaxial levels. The apparatus includes control means by which each of the variables involved is readily adjustable. There is relative axial movement between a rotary wire-laying flyer and the coil holder member. The apparatus includes means for applying a desired number of turns of wire to each level in a manner such that the spacing between turns is substantially constant, and the number turns applied to each level adjusted readily and easily.
