The invention relates to a machine for edge-milling (rumbling) concrete blocks (1) that have not yet hardened. Said machine comprises a horizontal conveyer (3) for transporting concrete blocks lying in one position on a support plate (2) and a hammer mechanism (4) located above the horizontal conveyer (3). The hammers (8) of said hammer mechanism (4) are positioned one behind the other in several rows in the direction of transport and are offset, so that they can hammer the surface of the concrete blocks (1*) lying below. The individual hammers (8) are suspended on lifting drives (13 to 19) that allow said hammers to swing.
L'invention concerne une machine pour biseauter (foulonner) des pierres en béton (1) non encore durcies. Cette machine comprend un convoyeur horizontal (3) pour le transport des pierres en béton (1) disposées dans une certaine position sur un bac (2) et un mécanisme (4) à marteaux pilons placé au-dessus du convoyeur horizontal (3). Les marteaux pilons (8) de ce mécanisme (4) sont disposés les uns derrière les autres et en quinconce en plusieurs rangs dans le sens du transport de façon à pouvoir marteler les faces supérieures des pierres en béton (1*) situées en dessous. Les différents marteaux pilons (8) sont suspendus de façon oscillante à des entraînements de levage (13 à 19).
