Apparatus for packaging photographic slides in envelopes

For use with a photographic slide mounting machine of the type having means for mounting slide transparencies in a supporting frame and means to eject the mounted slides from said machine;

• apparatus for packaging in a single multi-pocket envelope a plurality of such mounted slides, said apparatus comprising:
• means supplying a continuous flexible strip of envelope material formed to define a pair of spaced apart parallel rows of connected pockets, each row including a plurality of pockets arranged in opposed spaced apart relation to the pockets of the other row to form opposed pairs of pockets having inwardly facing slide-receiving mouth openings,
• a positioning head defining a packaging station and having said flexible strip slidably mounted thereon with means for holding said strip in doubled-back substantially U-shaped position to simultaneously expose the opposed mouth openings of a selected pair of pockets positioned at said packaging station,
• a shiftable guide track for transporting mounted slides from the ejecting means of the slide mounting machine to the packaging station and including means for selectively aligning said track with the mouth opening of one of said pockets to permit insertion of the slides successively into said respective pockets of said envelope from the slide ejecting means, and
• means for presenting successive pairs of pockets at said packaging station.
