Abstract

Chargeur pour bande comprenant un moyeu, une bande sans fin enroulée autour de ce moyeu et des moyens servant à guider cette bande depuis sa spire la plus intérieure jusqu'à sa spire la plus extérieure pour assurer le contact avec un mécanisme d'entraînement servant à exercer une traction sur la spire la plus intérieure et à faire défiler la bande devant un transducteur. Ce chargeur est caractérisé par le fait que ledit moyeu 14 est fixe, présente une ouverture centrale 16 et une fente 17 disposée axialement sur toute sa largeur, fente par laquelle on peut faire passer la bande 20 en provenance de la spire la plus intérieure de la bobine 22 et la tirer à travers cette ouverture centrale 16, avec ses bords sensiblement dans le même plan que les bords de ladite spire la plus intérieure, cette ouverture étant adaptée à recevoir le mécanisme d'entraînement 53 et le transducteur. Application aux bandes magnétiques.Belt loader comprising a hub, an endless belt wound around this hub and means for guiding this belt from its innermost turn to its outermost turn to ensure contact with a drive mechanism serving to exert a traction on the innermost turn and to make scroll the band in front of a transducer. This charger is characterized by the fact that said hub 14 is fixed, has a central opening 16 and a slot 17 disposed axially over its entire width, slot through which the strip 20 can be passed from the innermost turn of the coil 22 and pull it through this central opening 16, with its edges substantially in the same plane as the edges of said innermost turn, this opening being adapted to receive the drive mechanism 53 and the transducer. Application to magnetic tapes.
