Abstract
A web, contained in a cassette, is automatically threaded along an external transport path past a web utilization station, by means of a flexible threading band which pushes the web around the path. In a preferred embodiment, magnetic tape, contained in a cassette, is automatically threaded about a tape transport path past a magnetic head assembly by means of a flexible threading band contained in a threading band. The threading band is positioned behind a segment of the magnetic tape and is ejected from its own cassette, (1) to pull the magnetic tape out of the tape cassette, (2) to wrap the tape around a rotary head scanner of a magnetic tape recording/reproducing apparatus, and (3) to configure the tape to the tape transport path. After the tape is threaded, the flexible band is withdrawn into its cassette.
