Help finding paper on coil winding compression

Help finding paper on coil winding compression

(OP)
I used to have a paper that investigated how much you could compress magnet wire during winding to improve slot fill.  I can't find my copy and I don't remember the name or where it was published.  The amount of compression described in the paper was much higher than I had thought possible, but I can't remember how much this was.  The magnet wire was compressed enough to distort the cross section from round to a six sided shape (I think) without damaging the insulation system.  If anyone has a copy or can tell me where to get a copy I would be grateful.  Also, if there is any similar information available I would like to know.  Thanks in advance for your help.

See pages 3-32 thru 3-34 here. Page 3-34 talks about "compaction"

The context of the link I provided is fractional horsepower electric motors.

Electricpete,
Thanks for the link.  This is interesting, but what I'm looking for is information that gives the level that the magnet wire can be compressed without damaging the insulation.  A cross section of the coil bundle actually looks like a honeycomb (the wire is no longer round).  The paper that I'm referring to provided information about how much pressure could be applied to various insulation types (magnet wire).
