Abstract

Apparatus for introducing the leaders of webs of exposed photographic paper which is confined in cassettes into a dark chamber preparatory to threading of webs through a developing machine has a feed table with a channel for admission of webs into the chamber and an adapter with an open-and-shut housing for cassettes of different sizes. One section of the housing is separably mounted on the feed table and has an aperture in register with the channel as well as a pair of advancing rolls which lighttightly seal the internal compartment of the housing from the aperture and can be driven in opposite directions to advance the leader of a web into and through the channel. Another section of the housing is pivotable between open and closed positions to respectively afford access to and to lighttightly seal the internal compartment. The one section has pairs of internal platforms serving as supports for differently dimensioned cassettes.
