Abstract

Le dispositif pour la mise en œuvre du procédé est caractérisé en ce qu'un corps de manchon (9) est susceptible de coulisser d'une station de remplissage (1) avec une plaque de fond (10) à l'aide d'un organe de coulissement (11) dans une première station d'essai (2) et de là sur la plaque de fond (10) dans une deuxième station d'essai (3) et en ce que la station de remplissage (1) comporte une trémie de remplissage (5) munie d'un organe de pesée réglable (8). Application à la mesure instantanée des propriétés des matériaux de moulage, permettant la régulation en temps réel de l'installation de préparation de matériau de moulage.The device for carrying out the method is characterized in that a sleeve body (9) is capable of sliding from a filling station (1) with a base plate (10) by means of a sliding member (11) in a first test station (2) and from there on the base plate (10) in a second test station (3) and in that the filling station (1) comprises a filling hopper (5) provided with an adjustable weighing member (8). Application to the instantaneous measurement of the properties of molding materials, allowing real-time regulation of the molding material preparation installation.
