US Patent:

56467940, Jul 8, 1997

Filed:

Dec 1, 1995

Appl. No.:

8/566326

Inventors:

Kenneth Alan Lindsay - Brockport NY
Joseph Stanley Jastrzembski - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G08B 2100

US Classification:

360 3

Abstract:

A photofinishing apparatus for reading and/or writing magnetic information on a web of photographic film. The web comprises a plurality of individual strips of film secured together end to end. The apparatus includes a film track for receiving the web, a pair of drive rollers for moving the film web through the film track, a magnetic reader and/or writer for reading and/or writing magnetic data on the web, and a detection device for detecting metal objects in the web. The detection device is located at a point in the film track prior to the magnetic reader and/or writer. A monitoring device monitors the change in voltage across two space points on the film track for determining when a metal object is in the web and for producing a signal which is used to stop the film web.

Abstract:

A web motion control system for controlling the tension in a web advanced at a preset velocity in a web transport path between a supply reel and a take-up reel without the use of tension loops, particularly for use in transporting spliced together, developed filmstrips through a film preparation work station. The web (film) is advanced in the web transport path in either a forward or rewind direction in either a velocity mode or a position mode by a motor driven capstan roller. The supply and take-up reels have a hub over which the web is wound in unknown supply and take-up web winding diameters. Take-up and supply reel motors and encoders are attached to the take-up and supply reels for imparting torques to the reels in response to motor torque signals to prevent slack in the film segments between the reels and the capstan roller and to provide reel encoder output signals on at least each 360. degree. rotation of the reels. A metering encoder rotated with the capstan roller is employed to develop an encoder count signal.
