Abstract
Abstract Method and pinning devices for accurately registering art masters in operative relation in vacuum frame and photocomposition units for use in conjunction one with the other and in which the vacuum frame unit includes an improvement in the provision of a metal strip cemented to an underside of a resilient rubber mat of the vacuum frame unit, together with two locating pins projecting from the strip and through the rubber mat. The locating pins are spring loaded and sealed in cylinders brazed to the strip and project through openings formed in a baseplate of the vacuum frame unit, while the spring loaded pins in the cylinders are arranged so as to project through the mat and through holes accurately punched in a corresponding relation in photosensitive sheets of film of art masters to effectively locate the sheets of film in extremely accurate relation one to the other on the mat so as to facilitate repeated accuracy in the development of such art work.
