Device for producing dimensionally correct copies from originals which have form below the tolerance in terms of length

摘要

The undersize original (2) is fastened with one side edge (3) on the work surface (1) of a copier, the opposite side edge (3') is clamped into a profiled rail (6) which can be moved and adjusted perpendicular to a reference edge (4) so that the original (2) can be stretched to its required nominal size and copied. The device is used in particular for reproducing masters for conduction patterns of electronic assemblies, which masters have shrunk due to the ageing of the film material. <IMAGE>
