No I didn’t, and like the other commenter I don’t buy it either. My comment didn’t say you don’t put the axle into the roll, that’s very common for machines that are roll-fed. My comment said you don’t leave it laying around in the middle of a factory. Even with much smaller machines, eg a receipt printer, where you put the axle into the roll before installing it into the machine the axle is part of the machine and usually there’s only one. You pull it out of the depleted one as you take it out from the machine, put it in the new roll, and install that roll on the machine.
