Winds reel back (5)
I believe the answer is:
loops
'winds' is the definition.
(looping is a kind of winding)
'reel back' is the wordplay.
'reel' becomes 'spool' ('spool' can be a synonym of 'reel').
'back' is a reversal indicator.
'spool' reversed gives 'LOOPS'.
(Other definitions for loops that I've seen before include "Twists" , "Oval-shaped single coils, in a piece of thread perhaps" , "Winds" .)
