Abstract: A process for artificially ageing blocks, in particular concrete blocks, vitrified bricks and natural stones, provides that the blocks are applied to an underlying surface. Essentially freely movable distressing bodies are applied to the surface to be worked of the blocks. The blocks and the distressing bodies are brought into movement in relation to one another by a vibrating motion of the underlying surface in such a way that the distressing bodies act on the surface and the adjoining, exposed edges of the blocks.

Abstract: A device for lifting a layer of stones, particularly of artificially aged cast concrete stones, clinker bricks or natural stones, comprises a vacuum device with a suction opening for drawing up the stones. The suction opening (4) obtains, by means of changeable template elements (5), a pattern consisting of closed and open suction areas (6,7). The created pattern is essentially adapted to the respective layer of stones (1) to be lifted, and concentrates the suction power of the vacuum device, in essence, onto the upper surfaces of the stones.

Abstract: A device for tilting split stones, which have a broken structure on at least one surface such that a surface which is orientated laterally before the tilting process, is rotated to form the upper side of the stone after the tilting process. At least one receptacle is provided for a row of stones, the receptacle having a first bottom surface on which the row of stones rests in an initial position, and a second bottom surface on which the row of stones rests in an end position after the tilting process. A rotational axis extends along a connecting point between the two bottom surfaces and about which the receptacle is rotated to tilt the stones. An actuator is moved linearly and engages one of the two bottom surfaces such that the receptacle rotated about the rotational axis as a function of the linear movement of the actuator device.

Abstract: An apparatus for artificially ageing blocks, in particular concrete blocks, vitrified bricks and natural stones, has an underlying surface, on which the blocks can be placed in such a way that the surface to be worked and the adjoining edges are exposed. Provided here are essentially freely movable distressing bodies for applying to the surface to be worked and the adjoining edges. Also provided is a vibration device, to set 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. Further provided is an extraction device which extracts dust and/or fragments during the distressing action of the distressing bodies, the extraction device having a suction region which at least almost encloses the surface of the blocks to be worked.

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.
