Does the UM machine rotate the spool or does it pull the spool? You know what I mean? Does it unwind the material by pulling the material thus rotating the spool, or does the machine have a mech that rotates the spool to assist the feeding? In either case, you know the trick to handle large unspooled amounts might be to handle it like a box of wire.....pulling from the center. Putting the unspooled bundle in a box, tape down the "outside" end, then cut the wraps, and pull the center end out, things would likely stay totally fine. It's when you pull the outside end of an unspooled bundle that you create a nightmare birds nest.
