Abstract

L'invention concerne un appareil servant à mesurer la superficie de bandes allongées de différentes largeurs. Les bandes à mesurer sont introduites entre des rouleaux portés par des arbres parallèles, le nombre des rouleaux 21 portés à rotation libre par l'un des arbres, 19, étant choisi en fonction de la largeur des bandes. Ces rouleaux portent des aimants 24 de sorte que, lorsqu'ils sont entraînés en rotation par une bande, ils actionnent des interrupteurs à anche 31 coopérants qui appliquent des impulsions à un compteur totalisateur qui indique la superficie mesurée.
