The invention relates to a device for the shaping of conglomerates,preferably concrete conglomerates for masonry work, encompassing a form fortheinput of the concrete conglomerate, a table with which a form is coupled usingmounting components, a vibration generation system attached to table for thegeneration of harmonic vibrations and their transfer to table, a load in theform of apiston to admit the concrete conglomerate with a force, first springcomponents forthe elastic positioning of table, and second spring components for the elasticpositioning of load.In such a device there is a vibration generation system of at least eightrotating unbalance shafts provided with rotational axes parallel to eachother. Theunbalance shafts are coupled into pairs as to their rotational motion so thateach pairof unbalance shafts shares a rotational axis and is driven independently ofthe otherpairs.
