Abstract
A coil winding procedure for winding pairs of coils, whereby a first coil is wound inwardly to the start and the second coil is wound from the start to the finish lead from the same continuous conductor strand, thereby eliminating the need for a start-start brazing operation.
Claims5
A coil winding apparatus for winding adjacent pancake type coils, said apparatus comprising:
- (a) a winding table for supporting a coil during winding;
- (b) restraining barrier means on the table surface for defining the outer dimensions of a coil;
- (c) reel means adjacent to the table for storing and paying off a continuous strand of insulated metal onto the table and within the confines of the restraining barrier means;
- (d) forming means for pressing the continuous strand against the restraining barrier means during placement of the outer coil turn and against each successive inner coil turn as the strand is placed spirally on the table;
- (e) at least one of the forming means and the table being rotatable in such direction as to facilitate the placement of the strand in a spiral pattern, whereby a compact coil is formed;
- (f) the forming means comprising a retractable member having leading surface means for forcing the strand radially outwardly;
- and
- (g) the retractable member being pivotally mounted on the table, and includes drive means for rotating the member in the direction of placement of the strand on the table.
