Abstract
An automatic photographic print and film packaging mechanism inserts individual orders of prints and film into multilayered packaging envelopes formed in a continuous strip. The mechanism sequentially seals the sides of the envelopes and cuts the envelopes from the strip. The mechanism has provision for either sealing the top of a cut envelope and depositing the same in a first collection station or depositing the cut envelope with the top unsealed into second collection station.
