Abstract: A winding device comprised of parallel spaced supporting bodies on which an elongated flexible material is helically wound in a single layer. The bodies are interconnected by a folding mechanism, whereby the bodies can be axially displaced to reduce the distance therebetween and thereby reduce the length of one axis of the wound material while retaining the length of the other axis to permit transportation thereof in appropriately sized containers.

Abstract: A tape transport control system suitable for use in tape recording apparatus which utilizes supply and take-up reels onto which the tape is wound. The control system is coupled to both the supply and take-up reels so as to generate detection signals which represents the rotation of the reels. The circuitry utilizes the detection signals to determine the point at which each of the reels in nearing its end, and sends a control signal to the tape transport circuitry to stop the rotation of the reels.

Abstract: In a conventional ribbon supply spool structure which comprises a supply of ribbon wound on a hub rotatable about and axially movable with respect to a hub receiving member on which the hub is seated and which is coaxial with respect to the hub, an improved end of ribbon detection device is provided by the combination of deflectable spring means within the spool hub which exert a force when deflected having a first force component acting against but restrained by wound ribbon on the hub and a second component acting along the hub axis. A spring tensioned member exerts a force along the hub axis which opposes the component of force of the deflectable spring along the hub axis. In this manner, the deflectable spring and the spring tensioned member are maintained in static equilibrium at a selected point along said axis so long as the deflectable spring is restrained by a predetermined minimum of ribbon remaining wound on the hub.

Abstract: A bidirectional tape transport for tapes stored in cassettes providing fast forward and fast rewind functions. Fast forward and rewind are achieved by actuating controls which increase the motor speed and also release the tape from a capstan drive and the playback and recording head so that it may move freely at the fast speed. For fast rewind, the polarity of the supply voltage to the motor is reversed and those components of the bidirectional drive and the drive train to the reel spindles are reversed in such a way as to drive the supply spindle. Such operations are achieved by energizing a single solenoid by means of an electrical pulse produced by a switch actuated by the fast rewind control. The switch is so positioned that it will be actuated once during the advance stroke as the fast rewind control is pressed and once in the return stroke of the control.
