Abstract

Ce perfectionnement concerne les mesureuses de surfaces constituées essentiellement d'un cylindre rotatif d'axe horizontal sur lequel roule une série de disques rotatifs parallèles et indépendants les uns des autres, associés à des moyens électroniques tels que cellules photoélectriques permettant de détecter la présence ou l'absence sous chaque disque d'un objet qui défile entre le cylindre et la série de disques, et dont on désire mesurer la surface. Selon l'invention, le cylindre est constitué par une série d'anneaux coaxiaux, montés roulants sur deux tambours rotatifs d'axes parallèles entraînés en rotation, dont l'un au moins comporte à sa périphérie des moyens assurant le positionnement des anneaux précités, à l'intérieur desquels sont placées la ou les sources de lumière ou autre. Application aux machines de grandes dimensions.
