Abstract

Appareil et procédé pour créer une tension de bande constante dans un système de transport de bande, dans lequel les bobines d'alimentation et de reprise sont entraînées par coopération de surface avec un cabestan. Cette tension constante est obtenue en réglant le gradient de vitesse périphérique de la bobine d'alimentation sur celui de la bobine de reprise, qui est plus grand mais incliné de façon correspondante, par l'intermédiaire d'un système qui combine les effets de forces de couple et de rappel sur la bobine d'alimentation.
