Abstract (en)
[origin: EP1952960A2] The machine (1) has a fixed hopper (2) fed with concrete towards a vibrator mold (3). A lower retention mold (4) and the vibrator mold forming a definitive profile of a developed piece is provided at the interior of the fixed hopper and in a rectangular lower part of a settler and agitator assembly of the concrete. A lateral closure extends between the vibrator mold and the retention mold on a fabrication path (22) and is formed by a flexible closing lip (23) having a length equivalent to that of the closure.
