ABSTRACT:
A plant for the automatic weighing of dyes in powder form controlled by a computer for the preparation of mixtures for the dyeing industry comprising a plurality of hoppers containing the dyes, said hoppers being placed one beside the other, each being provided with pipe systems for the introduction of the dyes into respective loading hoppers provided with a lower conveyor chute for the withdrawal and introduction of the dye from the hoppers into a mixing and weighing container. When the conveyor chute is set into rotation, it withdraws the dye from the hopper and deposits it on the plate of the scale. The rotational speed of the chute is variable and it gradually decreases as the value weighed by the scale approaches the required weight value. The quantity of dye to be withdrawn and the withdrawing sequences are recorded and memorized in a computer which controls the operation of the plant.
