Abstract: front page image
(EN)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).
(FR)Appareil pour systeme de transport d"elements flexibles allonges plats (61) tels qu"une bande sonore, une pellicule de film, une bande audio-video, une pellicule de TV et autres avec face et dos lisses. La caracteristique nouvelle du systeme en question est l"entrainement synchrone par une courroie a dents de pignon a revetement non metallique (20) entrainee sur deux roues de pignons identiques (11a, 12a) montees chacune sur les arbres (11b, 12b) de deux roues identiques interchangeables (11, 12) pour le debobinage et l"embobinage. Par rotation synchrone d"axe symetrique des roues debitrice et receptrice (11, 12), la bande (61) est transportee a une vitesse constamment reguliere, sans tension/trainage/saccade. Dans le systeme, la longueur continue de la bande (61) deroulee de la bobine debitrice (11) est transportee sur la bobine receptrice (12) et empilee dans la bobine receptrice (12), chaque tour en position correspondante par symetrie d"axe a celui deroule de la bobine debitrice (11).
