The ''Typewriter Platen'' is the biggest roller located inside the typewriter carriage. When the metal key heads hit the ribbon and the paper, the correct hardness of that rubber cylinder permits to print on the paper the characters. Correct hardness for platen is between 85-90 Shore A (equal to 34-42 Shore D). With a platen of 85-86 Shore A you have comfortable but not very precise writing, with a platen of 89-90 Shore A you have a very precise but less comfortable writing. So we studied a customized rubber compound which is 87-88 Shore A, the best compromise!
Vescovo-Restauri makes a scientific measure of the hardness and the diameter. If the hardness is correct, but the rubber is ''corrugated'' the platen will be only rectified. If it has already been rectified in the past, so the diameter is too small, that operation cannot be done. If the measured hardness is incorrect we proceed with a new rubber coating.
The passages of the work are shortly that: typewriter platen will be take on lathe for remove old rubber, sandblasted, coated with virgin rubber, vulcanized in an autoclave, rectified and manually refine on the lathe with the correct roughness and bevel.
