Reader-filler machine for microfilm jackets operable in insertion or

Abstract

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 its rear end. The jacket to be loaded is placed on a platform that is shiftable stepwise with respect to a film trackway guiding a film web, the trackway being parallel to a film pusher station. In the insertion mode, after a section of film of a desired length is extended from the trackway for insertion in a given channel through its entry slot, an automatic three-phase insertion cycle is initiated. In the first phase, the section is cut to produce a film chip whose tail projects beyond the entry slot. In the second phase, the platform is indexed one forward step to align the next empty channel with the trackway and the tail of the chip with the film pusher. In the third phase, the film pusher acts to engage the tail and push it into the channel, thereby loading the chip in the channel. Operation in the structuring mode, which involves an automatic four-phase cycle, is reserved for chips whose length is shorter than the channel length, this operation serving to push the chip within the channel to a point where its leading edge coincides with the front end of the channel. The first three phases of the structuring mode are the same as in the insertion mode, this being followed by a fourth and final phase in which the platform is reverse-indexed to bring the loaded channel back into line with the trackway, making it possible for the operator to advance the film web into the channel to engage and push the chip therein to the desired point.
