ABSTRACT:
Methods and apparatus for selecting increments of relative travel of portions of at least one coil insertion apparatus in response to the actual height of a selected magnetic core and interdependently adjusting the mechanical interrelationships between two or more parts of winding turn establishing means of winding apparatus so as to provide one or more turns of conductive material having a size and shape that is particularly adapted for placement in slots of the selected magnetic core. During the interdependent adjustment, one or more additional coil insertion apparatus may be interdependently adjusted. In one approach, a gauge measures actual axial length of core and mechanism concurrently sets up winding size determining means. The gauge may be coil insertion apparatus.
Also disclosed are apparatus and methods for: adjusting winding turn size (this being related to stack height); for adjusting the "span" of winding turns so that they may selectively be of "odd" or "even" span; and for selectively determining relative angular indexing of winding turn receiving means so that the polar axes of adjacent coil groups may be angularly displaced substantially any desired amount. Winding apparatus includes winding turn size determining means that are made up of a plurality of parts, at least some of which are movable relative to one another so as to provide winding turns of a desired span and size.
