Abstract
A casted concrete block surface-roughing machine having an in-line conveyor displaceable over a stationary horizontal support surface for slidingly supporting a lower surface of concrete blocks displaced thereon by the conveyor. At least two pairs of spaced-apart vertically supported conveyor belts are disposed to engage opposed side faces of the concrete blocks to displace them along the stationary horizontal support surface. One of the pairs of the conveyor belts engages the opposed side faces in a lower surface section thereof to expose an upper surface section thereof to be abraded by respective surface abrading devices. The other of the pairs of conveyor belts engage the opposed side faces in the upper surface section of the concrete block to expose the lower surface section thereof to be abraded by further respective surfaces abrading devices.
