While cleaning our new Uni III, one of my students managed to get a rag caught in the drive cylinder gear. They wisely cut the motor off and unplugged the machine, but our attempts to The chain is very tight; I cannot find any wiggle room to get the rag out. I’m now trying to cut it out bit by bit, but thought I would post here to see if anyone has a better plan.

Thanks to all who responded. We were able to get the rag out by tearing and cutting, bit by bit. I could not find any adjustment for the chain tension, something that we could have loosened to get the rag out. Needless to say, there will be some training this week on proper cleaning of the drum cylinder!
We could use a manual. Is Fritz Klinke still the GO TO guy for that?
There is a removable link in that chain, if you are lucky enough for it to be accessible when the chain stops. After the burn-off, it might be a good idea to remove the chain, clean and relubricate it. (Oil thinned with kerosene, spray chain lube, whatever.)
Also, there will be a way to ease the chain tension (there’s an idler or something that can be eased off, right?) just enough that you could back the jam out by pulling the chain against normal travel direction.
It’s more likely on models with an open well for a rubber ductor roller next to the ink drum. You could have a cover fabricated similar to the one one your SP15.
Wow. That seems drastic. I take it this is not an uncommon problem with this machine?
One printer I know told me that she cut away the excess, then burned the rag. Just make sure that you have a fire extinguisher at the ready.
