Abstract: A closed loop, high-speed tape transporter (10) includes a vacuum supply (11A), a first vacuum column (40) operatively connected to the vacuum supply (11A) and positioned upstream from a pick-up head (100) and downstream from a tape bin (64) for receiving the loop of tape and exerting a vacuum-induced holdback tension thereon, a second vacuum column (50) operatively connected to the vacuum supply (11A) and positioned downstream of head (100) and upstream of the tape bin (64) for exerting a vacuum-induced pull forward tension on the tape in opposition to the holdback tension exerted on the tape by the first vacuum column (40). A motor-driven capstan (60) is positioned intermediate the pick-up head (100) and the second vacuum column (50). Capstan (100) is driven at a constant speed equal to the ideal reference tape duplication speed. Tape drive capstans (62A) and (70A) cooperate with the first and second vacuum columns (40) and (50) for moving the tape.

Abstract: As tape moving at high speed through a closed loop tape transporter (10) is conveyed into a storage bin (64) the tape is directed against a curved tape deflecting surface opposite and in spaced-apart relation to the bin entrance (63). A plurality of vacuum ports (96) are positioned in spaced-apart relation generally along the path of tape movement on the tape deflecting surface (64A). As the tape moves along the tape deflecting surface (64A), vacuum-induced drag is applied to the tape to create a progressive breaking force which slows the tape and causes the tape to form into loops. The loops assist the tape is accumulating in the bottom of the bin in a controlled manner.

Abstract: As tape moves through a closed loop, high-speed tape transporter (10) loops of the tape are accumulated and stored in a tape bin (64). The capacity of the tape bin (64) is increased by extracting air from and lowering the air pressure in the region of the bin (64) occupied by the loops of accumulated tape and inside the loops of tape sufficient to cause the accumulated tape to compress into tighter loops which occupy less space in the tape bin (64). Air extraction takes place through a vacuum port (95) which communicates with the interior of the tape bin (64) and which is connected to a vacuum supply (11A).

Abstract: A magnetic storage indicator (40) is disclosed for use on a recording tape processing apparatus, such as a cassette winder (10). Magnetic storage indicator (40) comprises a recording head (50) and a downstream playback head (51). Signals received at the playback head (51) are transmitted to a pre-amplifier (60), an equalization circuit (70) and a record amplifier (80) and then back to the recording head (50) where the amplified signal is recorded onto the moving tape. If the oxide layer is on the side of the tape in contact with the record head (50) and the playback head (51) a feedback loop is completed, causing the circuit to oscillate. This condition is transmitted to a light emitting diode (48) indicating that the tape is properly wound.

Abstract: A vacuum column (34) is used in a closed loop, high-speed tape transporter (10) to maintain constant tension on a moving loop of tape as it is delivered to a pick-up head (20) of the transporter (10). A motor driven capstan (35) intermediate a tape storage bin (23) and the vacuum column (34) pulls the loop of tape from bin (23) and delivers it to the vacuum column (34). A servo-control (39), (40), (41) senses changes in the position of the tape within the vacuum column (34) caused by tension changes of the tape within the bin (23) and sends a signal responsive to the change of position of the tape in the vacuum column (34) to the capstan motor (31), thereby changing its speed sufficient to maintain the position of the tape within capstan (34) at a relatively constant level. Sensing can be by means of a vacuum slot (34), an ultrasonic proximity indicator (42) or a series of photo-optical sensors (44), (45).

Abstract: An integrally formed ratchet (90) and star wheel (95) is disclosed which rotates in unison with a tape applicator wheel (85). Eccentrically formed fingers (96a-d) cooperate with a downwardly facing wall to align and position applicator wheel (85) into correct position after each reciprocation of the splicer (30). Correct alignment is essential because a cutter blade 127 cuts the tape on the applicator wheel into pre-determined lengths by passing through a notch (104) in applicator wheel (85). Misalignment of the applicator wheel (85) may cause blade (127) to impact the applicator wheel (85) itself, damaging or destroying it.

Abstract: An audio tape cassette winder (10) is disclosed which includes a splicer (30) which winds splicing tape ("T") onto a cassette ("C"). Tape ("T") is applied by means of a square applicator wheel 85 which simultaneously translates and rotates into and out of tape applying contact with two tape ends ("L" and "A") to be spliced. Application of tape ("T") to tapes to be spliced ("L" and "A") is assisted by positive air pressure through ports (106a-d) on respective tape carrying surfaces (85a-d) as each tape carrying surface successively applies tape ("T") to the tapes to be spliced ("A" and "L"). The positive air pressure is applied only for a very short period of time concurrent with physical impact of successive tape carrying surfaces (85a-d) with the tapes to be spliced ("A" and "L"). The invention proceeds substantially as described above with reference to the apparatus.
