That part is relatively easy. The 'roller' is more complicated than it
appears, though, it's made of 2 rubber-coated plastic cylidners that run
loosly on the shaft. Inside the end of each cylinder is a bevel gear,
there's another simiar gear monted on a pin sticking out from the shaft.
The whole lot forms a differential gear, of course, which I believe is
there to keep the paper running striaght.
Still, it all comes apart, and you end up with the 2 bits of the roller
that you can clean up.
Interestingly, it shows a Vesatec V80. Exactly the same thing has
happened to the platten roller in my V80 :-(, so sometime I am
going to
have to work out how to repair that,,,
Would it be possible to extract the roller and clean it, then use multiple
layers of inner tube to make it up to the right thickness? Use an
adhesive
to stick the layers together and to the metal roller otherwise they will
work themselves up toward one end. Inner tubes are available in a
wide range of sizes from bicycles, trade bikes (mountain these days?),
motorcycles, cars, lorries and tractors and they can be stretched a lot.
It's not that big -- perhaps 3cm diameter at most. I would think some
suitable tube could be found.
The other possibility is to use one of the 2 pack 'rubbers' made by e.g.
Devcon. Make a mould, centre the inner part of the roller in it, and pour
in the 'rubber'. Let it set overnight and hope :-)
