Abstract

Dispositif de détermination rapide de la fluidité d'une poudre de caoutchouc après stockage. La poudre 4 est versée dans un gobelet cylindrique 1, dans lequel est introduit un élément résistant 7. Ce dernier délivre une valeur analogique par l'intermédiaire d'un couplemètre quand une rotation relative est produite entre le gobelet et élément résistant.
