Abstract
Una disposición de accionamiento de cinta magnética en bucle cerrado, que comprende: un bastidor; un carrete de suministro para desenrollar una longitud de cinta magnética enrollada en el mismo; un carrete tomador para tomar la longitud de cinta magnética desenrollada por el carrete de suministro; unos medios de accionamiento para el carrete de suministro, unos medios de accionamiento para el carrete tomador; un eje de accionamiento para impulsar a la cinta magnética con una velocidad definida exactamente; un primer y un segundo rodillos de presión para empujar a la cinta magnética contra la polea en posiciones sustancialmente opuestas, un miembro de guía de cinta alrededor del cual se hace pasar la cinta que viene de la polea de modo que sea hecha retornar a la polea, de manera que en la cinta magnética se forme un bucle que está bajo tensión; una pluralidad de cabezas magnéticas para cooperación con la cinta magnética en el bucle, y un dispositivo de control para mantener constante, dentro de ciertos límites, la tensión en una parte de la cinta magnética aguas arriba de dicho bucle en la cinta transportadora.
