Patent ID: 7527487

Claim:
A device for shaping conglomerates, comprising: a form for the accepting concrete conglomerate; a table coupled to the form; a vibration generation system coupled to the table, the system adapted for generating harmonic vibrations and transferring the vibrations to the table; a load adapted to admit the concrete conglomerate with a force; first spring components for elastic positioning of the table; second spring components for elastic positioning of the load; and wherein the vibration generation system includes at least eight rotating unbalance shafts having rotational axes parallel to each other; and wherein the unbalance shafts are coupled in pairs in their rotational movement so that each pair of unbalance shafts shares a rotational axis and is driven independently of the other pairs, at least one of the pairs comprising two unbalance shafts coupled with an elastic coupling having a torsion strength of at least 10 4 Nm/rad and a maximum radial spring strength of 2×10 7 N/m.
