Structuring mechanism in reader-filler machine for microfiche jackets

Abstract

A structuring mechanism for a reader-filler machine adapted to cut and insert sections of microfilm into the channels of a multi-channel microfiche jacket, each channel having an entry slot adjacent the rear end of the jacket. The jacket to be loaded and structured is placed on the inclined platform of a carriage that is shiftable stepwise in a path at right angles with respect to a stationary film trackway. A retractable film pusher operates at a pusher station parallel to the trackway. After a section of film is inserted in a channel and is cut from the film on the trackway to produce a film chip whose tail extends outside of the channel entry slot, the platform is then indexed to bring the next empty channel into line with the trackway, the tail of the chip being brought by this step into alignment with the film pusher which acts to engage the tail and push it into the channel to complete the insertion. The structuring mechanism is used for chips whose length is shorter than the channel length, this mechanism serving to advance the chip in the channel to a point where its leading edge coincides with the front end of the jacket. This mechanism includes a retractable structuring pusher which operates at the pusher station above or below the film pusher. The structuring pusher is adapted to engage the trailing edge of the film chip in the channel and to push the chip to the desired position.
