Hi Mancgirl, thank you for the link - it worked just fine. Yes, running a machine like that would definitely have kept you busy, plus as you say, the continuous noise that went with it as well would have made for a very long day, I'm sure. I recall a guy I knew very briefly where I used to work in the early 1990's who mentioned about having worked at Courtaulds, so I'm assuming it would have been the same kind of machinery you were operating.
