The ''Typewriter Platen'' is the biggest roller located inside the typewriter carriage. When the typebar hits the ribbon and the paper, the correct hardness of that rubber cylinder permits to print on the paper the characters. A hardened platen causes a noisy writing and can also severely damage the hammers. The perfect hardness for new platens of manual typewriters is 88±1 Shore-A, while on electromechanical models this value is a few points higher. The compound used by Vescovo Restauri is a special blend of SBR and NR (styrene-butadiene and natural rubber) which guarantees excellent elastic response, low noise and long life.

When a platen is delivered to the company, hardness and diameter values are measured in order to be compared with reference values. In the event that one of the two values are incorrect, we will proceed with the new rubber covering. From past experience, it can be said that a hardened platen up to a maximum of 96 Shore-A can still be used by customers who intend to write sporadically. But for customers who write intensively, the hardness of the platen should not exceed 93 Shore-A. If the hardness is correct, but the rubber is ''corrugated'' the platen will be only rectified. But if it has already been rectified in the past, so the diameter is too small, that operation cannot be done and so we proceed with a new rubber coating.

The passages of the work for a new rubber coating 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.
