Rubber blanket reused interminably (8)

I believe the answer is:
masseuse
'rubber' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for masseuse that I've seen before include "Manipulator of body" , "She kneads bodies" , "Uses same sort of woman who kneads muscles to lessen stiffness" , "Uses seam (anag)" , "Female rubber?" .)
