The assembly drives two independent punch heads. The heads slide along linear rails, index to the drum, punch the film, and evacuate the slugs. This device is used in the Dianappon Screen film recorder and has 3 micron repeatibility throughout the recorder's 40,000 hour (seven years continuous) field life
The assembly is configured such that the whole unit (pnuematics, electronics, mechanics) can be assembled as a unit, then bolted to the image recorder.
