Abstract: A method for roughing surfaces and edges of concrete casted blocks, comprising a block support surface having a plurality of surface sections. A first of the surface sections has a rear end thereof above an adjacent front end of a second of the surface sections to create a ledge for projecting a leading edge portion of concrete blocks conveyed over the first surface section. A first roughing device has a plurality of impacting elements thereon for roughing concrete blocks. The first roughing device is disposed generally above the rear end of the first surface section for abrading a projecting leading edge portion of each concrete block as they are conveyed over the rear end. A conveyor displaces concrete blocks over the first and second surface sections, the blocks being tilted when reaching a predetermined position over the ledge to avoid being abraded by the roughing device.
