Abstract

An apparatus for artificially aging blocks such as concrete blocks, vitrified bricks and natural stones, having the following features. An underlying surface, on which the blocks can be placed in such a way that their surface to be worked and the adjoining edges are exposed. Essentially freely movable distressing bodies for applying to the surface to be worked and the adjoining edges. A vibration device sets the blocks and the distressing bodies in motion in relation to one another in such a way that the distressing bodies act on the surface and the exposed edges of the blocks. A limiting device restricts the lateral or horizontal movement of the distressing bodies essentially to the surface of the blocks. A magnet for at least one of depositing and removing the distressing bodies. The height of the limiting device is reducible and/or the limiting device is displaceable in such a way that the magnet can be brought close to the surface of the blocks for the depositing and/or removal of the distressing bodies.
