Number: 242/324
Name: Winding, tensioning, or guiding > Unwinding and rewinding a machine convertible information carrier (e.g., magnetic tape or photographic film)
Description: Apparatus or corresponding method for handling elongated material, specifically, information-bearing carrier having a signal or coating thereon which is transformable into a useful form, which apparatus or method involves the following cycle: (a) uncoiling the elongated material from a supply coil, (b) directing the material along a path past a work station (e.g., a transducer head, lens, or shutter), of a utilization device, and (c) recoiling the material on a take-up coil.
