Patent number: 4574563Abstract: A method and apparatus for continuously producing photographic film, comprises perforating film strip, applying characters to the perforated film strip as latent images, and cutting it into sized film strips. The photographic film strip withdrawn from a roll of film is perforated along its longitudinal margins and then provided with characters as latent images such as frame numbers, symbols and the like. After the provision of characters, the photographic film strip is cut into sized film strips which are thereafter wound into containers. The film moves continuously lengthwise from the time it is withdrawn from the supply roll, to the time it is rewound in the containers as sized film strips. In this way, the cost of equipment and labor is reduced.Type: GrantFiled: January 23, 1984Date of Patent: March 11, 1986Assignee: Fuji Photo Film Co., Ltd.Inventor: Shigehisa Shimizu

Patent number: 4515052Abstract: A duplex slitter scorer mounted on a single pivoted sub-carrier is provided with a single power adjusting apparatus disposed entirely below the paper feed path. The adjusting apparatus includes a single rotatable lead screw to position a common carrier mounting first and second relatively movable adjusting arms that are selectively engageable in sequence with the slitting and creasing heads. The lead screw axis is fixed transversely and both adjusting arms are retractable to permit indexing of the pivoted sub-carrier. To compensate for paper weave, the sub-frame is moved along its pivot axis. The lead screw is fixed against longitudinal movement but is partially controlled by a signal indicative of sub-carrier position along its pivot axis so that the instantaneous position of the adjusting apparatus common carrier is related to the instantaneous position of the sub-frame along its pivot axis.Type: GrantFiled: September 24, 1982Date of Patent: May 7, 1985Assignee: S&S Corrugated Paper Machinery Co., Inc.Inventor: Stephen S.
