Abstract

Dispositif de mesure d'un poids par unité de surface de matériaux en combinaison. La combinaison de matériaux constituée par un carton 1, un revêtement en CaCO3 , 2, et un revêtement de surface en kaolin 3 est irradiée par un rayonnement provenant d'une source à radioisotope 4; les rayons X émis par cette source excitent le rayonnement à rayons X secondaire du calcium présent dans la couche 2, dont l'intensité est mesurée au moyen des détecteurs 6 et 7 des deux côtés du carton 1; le détecteur 5 est en outre utilisé pour mesurer l'absorption du rayonnement primaire provenant de la source 4 dans la combinaison carton-revêtement Dispositif de mesure de poids par unité de surface d'une combinaison de matériaux sur une machine de revêtement de papier ou de carton.
