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: An apparatus for the artificial ageing of blocks, in particular concrete blocks, clinker bricks and natural stone blocks, has a base on which the blocks can be placed in such a way that their surfaces to be treated and the adjoining edges are exposed. Essentially freely movable striking bodies are used for treating the surfaces and the adjoining edges of the blocks. A vibrating device sets the blocks and the striking bodies in motion relative to one another in such a way that the striking bodies act on the surfaces and the exposed edges of the blocks. In this case, the striking bodies are movably fastened to a retaining device in such a way that the striking bodies are freely movable within a defined region of the surface 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.
