Picked up a few things from an auction.
It was from a company who made machines recovering tobacco from cigarettes.
Heh?
That was what I thought too. One of the employees explained when I asked what a tobacco recovery machine was.
If cigarettes gets rejected (damaged, not straight, filter crushed or whatever) they use a tobacco recovery machine to remove the filter and paper from the tobacco so the tobacco can be re used.
My first proper engineering job was with Philip Morris Engineering in London 30 yrs ago - they rebuilt their own cigarette making machines, built special purpose machines. Cigarette making machines back then could run 15,000 cigarettes a minute - doesn't take very long with an issue - a stuck cigarette, a bent bit of card, a slightly misaligned guard, before you've made a lot a of damaged cigarettes.
They used to test machines with just filter material - then finally with tobacco. Bonded warehouse on-site so tobacco used specifically for testing and then destroyed did not have to have duty paid/could be recovered, I forget which.
