Abstract
Pneumatic copier, characterized by the fact of consisting of a pneumatic cylinder with pressure regulator and exhaust valves that longitudinally moves a carriage with a suitable stroke according to the piece to be copied and at the end of which is arranged a gearmotor whose axis is integral with a tool - template provided with means to support the piece; of a filing or polishing head comprising an elastic contact pulley on which an abrasive abrasive belt or a polishing disc and a rotating metallic disc are applied by contact with the tooling-template and which, by means of a micrometric longitudinal translation, provide the programmed advance and return of the motor carrying the part to be collected in order to maintain the correct working pressure constant.
