Aufbewahrungssystem für photographische Negative sowie Verfahren und Vorrichtung zu dessen Herstellung

摘要

When photographic film has been processed and printed, the photographer receives a set of prints and negatives in an envelope. However, because negatives are susceptible to scratching and contamination from dust, dirt and/or fingerprints, the quality of reprints and/or enlargements made from damaged negatives is reduced. Described herein is a method and apparatus which uses heat to bond a polyethylene sleeve (9, 21, 22) having pockets (21, 22) which contain negative strips (13, 14) to the non-image bearing surface (11) of a photographic paper (10) coated with a layer of polyethylene (12). A positive image or index print of the information stored on each negative strip (13, 14) appears on the image bearing surface (24) of the photographic pape (10) aligned with the correct negative strip (13, 14). Each pocket (21, 22) is formed by heating portions (15, 16, 17) of the sleeve material (9) to bond it to the non-image bearing surface (11, 12) with the negative strip (13, 14) in place.
