Wind off of a spool (6)
I believe the answer is:
unreel
'wind off of a spool' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for unreel that I've seen before include "Wind like film in a projector" , "Pull out tape" , "Take from coil" , "Unfurl" , "sounds amazing" .)
