Abstract

Le dispositif comprend une bande 23 fixée à ses deux extrémités respectivement à une bobine d'emmagasinement 20 et à une bobine d'alimentation 22, qui tournent en sens inverse. Des feuilles 24 à emmagasiner, puis à distribuer sont amenées sur la bande et sont entraînées par elle. Suivant l'invention, la bande est entraînée par le frottement d'un rouleau 21 entraînée en rotation à une vitesse constante par une roue dentée 26 en liaison avec les deux bobines par l'intermédiaire de deux autres roues dentées 25 et 27 et d'embrayages à glissement 28 et 29. Application particulière: emmagasinage et distribution de pellicules radiographiques.The device comprises a strip 23 fixed at its two ends respectively to a storage reel 20 and to a supply reel 22, which rotate in the opposite direction. Sheets 24 to be stored and then distributed are brought onto the belt and are driven by it. According to the invention, the strip is driven by the friction of a roller 21 driven in rotation at a constant speed by a toothed wheel 26 in connection with the two coils by means of two other toothed wheels 25 and 27 and of slip clutches 28 and 29. Particular application: storage and distribution of x-ray films.
