Pressing machine (6)
I believe the answer is:
mangle
'pressing machine' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mangle that I've seen before include "Ruin" , "Old-fashioned clothes dryer" , "Squelchy washing squasher" , "Clothes-squeezer" , "Squeeze" .)
