Abstract
Abstract Apparatus comprises winding assembly that includes a wire disposing or placing means (e.g., a flyer) that generates turns of wire about a forming means that preferably comprises two or more sections. The forming means or former assists in determining the configuration (e.g., size and shape) of a winding turn as it is being generated. Coil former is longitudinally shifted relative to the flyer after a predetermined number of turns of wire are generated about a first former stage and an intercoil winding segment is generated in a desired manner. During the shift, a predetermined number of winding turns are disposed upon a second stage of the former. In a preferred method, the coil former advances at a preselected speed greater than the winding turn feed rate while the intercoil winding segment is being generated. The former advances relatively slowly in order to secure the advantages associated with reduced machine part accelerations, velocities, and decelerations. The former includes a transition region that advances through a wire disposing plane associated with the flyer. This region includes a wire accommodating ledge or step. During development of the coils and generation of the intercoil segments, a lead is established between the segments and adjacent winding turns to facilitate the development of an accurate number of turns as well as the desired placement of wire. Advance or jump speed of the turn former is preselectively determined and controlled.
