Method according to which the concrete is introduced into a mould (7) placed on the vibrating lower plate (4) of a press and the concrete is compacted in this mould with the aid of a rammer (10), which method is characterised in that the moulded objects (15) obtained are weighed, this weight is compared with a reference value and, as a function of the value of the discrepancy, an automatically controlled device is used to adjust at least one of the parameters, duration, amplitude and frequency defining the vibrations of the plate (4) in order to cancel out this discrepancy value. <IMAGE> |
