In an operating apparatus a system for transporting flat elongated flexible element (61) such as sound tape, movie film, audio-video tape, t-v tape and the like with smooth face and back. The novel feature of the subject system is the synchronous driving by an endless non-metallic-clad sprocket belt (20) trained over two identical sprocket wheels (11a, 12a) fitted one each to the drive shafts (11b, 12b) of the two identical hence interchangeable wheels (11, 12) for supply reel and for take-up reeling. By synchronous axisymmetrical rotation of the supply and take-up wheels (11, 12) the tape (61) is transported in steady continuously evenly set pace, without tension/lag/jerk. In the system the continuous length of tape (61) payed out from the supply wheel (11) is transported to the take-up wheel (12) and stacked in the take-up wheel (12) every round in the corresponding axisymmetrical position to that displaced in the supply wheel (11). |
