There was an occupation called Smoother. I am unsure what it related too though but find attached a census report from 1911 for Belfast in which the head of household was listed as having an occupation of "Smoother". There were a lot of linen mills and factories in Belfast at this time and I would hazard a guess that it was a process in that manufacturing process. http://www.census.nationalarchives.ie/reels/nai001460568/
