Arrangement for automatic simple noble of a flexible recording band is in a band guidance path between a strip storage reel, on which the strip is wound up, and a belt receiving coil of a belt transport machine

摘要

Apparatus having an automatic tape loading path extending between a file reel and a machine reel, such as a digital magnetic tape transport, incorporates a physical end of tape (PEOT) sensor, an air jet forcing the physical end against the sensor, and control electronics. As the file reel is rotated in the tape wind direction after loading, the air jet forces a length of tape near the physical end thereof into contact with the sensor which provides a control signal when the physical end of the tape passes the sensor. The control electronics continue rotation of the file reel through a predetermined angular distance to align the physical tape end with a preload point of an automatic tape loading path. This apparatus simplifies tape loading by automatically aligning the physical tape end with the tape loading path and provides a fully automatic detection of improper loading and a retry if a first attempt at automatic threading is not successful.
