<p>A pouring machine for supplying metered quantities of a material to be poured comprises a support framework (2, 3), a container (4) which is associated with the framework and can receive a filling of material to be poured, a pouring unit (5) having a plurality of pouring ducts (55, 59, 60) which can receive the material to be poured from the container (4) and which have respective pouring nozzles (56) associated with their lower ends, at least one set of pistons (51) arranged side by side and each mounted for sliding in a respective cylinder (60), the sliding of each piston (51) in the respective cylinder causing the expulsion of a metered quantity of material to be poured through a respective pouring nozzle (56), and actuator means for bringing about the sliding of the pistons (51) inside the cylinders (60), the actuator means acting on a plate (61) to which the proximal ends (62) of the pistons (51) are articulated, the distal ends (65) of the pistons being covered by a bush (67) of yielding material, a stirrer member (41) associated with the container (4) and capable of remaining continuously immersed in the material to be poured so as to stir the material to be poured for delivery to the pouring unit (5), and means for moving the pouring unit (5) along an axis substantially perpendicular to the axes of the sliding of the pistons (51) and of the expulsion of a metered quantity of material to be poured. <IMAGE></p> |
