Abstract
Apparatus and method for updating microform information recorded in a sequence on photographic film emulsion, including taking a desired portion of the emulsion carrying an image and bonding it to a primary base material either in the same sequence but with gaps left in the sequence or in a different sequence. The emulsion is bonded into sunken areas in the base material, the sunken areas either being formed by indented portions in the base material or by applying an apertured frame surrounding a flat base material.
Claims14
A method of microform updating comprising the steps of:
- a. recording photographic images in a sequence on photographic emulsion, the emulsion being incorporated in or applied to a layer of permanent carrier material,
- b. temporarily bonding said permanent carrier material to a temporary carrier base material,
- c. feeding said temporary carrier base material carrying said emulsion and permanent carrier material to a transfer station,
- d. selecting one of the images recorded on the emulsion from the sequence at said transfer station,
- e. feeding a strip of primary base material having sunken areas defining image frames formed therein to said transfer station,
- f. removing the emulsion and permanent carrying material containing the one selected image from said temporary carrier base material,
- g. bonding said one image recorded on emulsion to said primary base material in one image frame at said transfer station,
- h. selecting a further one of the images recorded on the emulsion from said sequence at said transfer station,
- i. moving said strip of base material to locate a further said image frame at said transfer station,
- j. bonding said further image in a further said image frame spaced from said one image frame by at least one other said frame or before said one frame relative to said recording sequence, whereby the sequence of images on the resultant combination of emulsion carrier and base is modified from said recording sequence.
Apparatus for microform updating comprising a microform camera for recording a sequence of images on a film emulsion, means for moving said film emulsion retained on permanent carrier material to a transfer station, means for feeding a strip of primary base material to said transfer station and means for applying said film emulsion and permanent carrier material to said primary base material at said transfer station, said means for applying a plunger having an interconnected and surrounding blade, said blade adapted to cut an image-carrying frame from said film emulsion and said plunger being adapted to remove said frame and bond said carrier material to said primary base material.
