ABSTRACT:
In combination with a tape machine having at least one reel with a tape wound thereon, a device is provided which positions the tape at a predetermined point and comprises a tape speed sensor which generates speed signals indicative of variations in the speed of the tape while the tape is wound in respect to the reel, a calculator which receives the speed signals and calculates the inertia of the wound tape from them, and a control circuit which generates control signals to stop the tape machine with the tape positioned at the predetermined point in response to the calculated inertia of the tape.
