In addition, a feed device is provided in order to push at least two rows of stone blocks, which are arranged side by side in the feed direction and are formed in each case by several stone blocks placed one behind the other, through the ageing duct, wherein the stone blocks of the rows of stone blocks are placed in such a manner on the base of the ageing duct that the stone block surface of the stone blocks to be treated is aligned transversely with respect to the feed direction.

Abstract: A method for producing concrete blocks, and in particular paving stones, building blocks or the like, with a storage container forming a receiving space for a plurality of layers of different-colored concrete, dispensing means being provided in order to dispense partial amounts of the layers from the receiving space in such a way that a downstream release device receives a mixture of the layers of different-colored concrete, characterized in that at least a partial portion of a side wall of the receiving space is provided with at least one dispensing opening for dispensing a partial amount of the layers, the size of passage of the dispensing opening being variable by the dispensing means.

Abstract: Device for the artificial aging of stones with at least an aging channel arranged on a support, a vibration device to set the support in motion, and a conveying device to move the stone through the aging channel. The aging channel has at least a first and a second impacting surface, which apply the aging effect to the stone. The aging channel comprises at least two sections, wherein the stone moves through a first section in a first feed direction and wherein a second section runs at an angle to the first section, so the stone is deflected in its feed direction to move into a second feed direction.

Abstract: The invention relates to a device for producing concrete blocks, particularly paving stones, building blocks or the like, comprising a storage container forming a receiving chamber for a plurality of layers of concrete in different colors. Dispensing means are provided, in order to dispense partial amounts of the layers from the receiving chamber such that a release device connected downstream receives a mixture of the layers of concrete in different colors. At least a partial section of a side wall of the receiving chamber is provided with at least one dispensing opening for dispensing a partial amount of the layers. The size of the passage of the dispensing opening can be varied by the dispensing means.

Abstract: The present invention relates to a paving stone having stone flanks which are oriented perpendicular to the laying plane, and wherein the paving stone has interlocking elements of a stone flank of an adjacent paving stone.

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.

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 sorting blocks made of concrete or concrete-like material, in particular paving slabs, having a vibration arrangement and a sorting arrangement which slopes with respect to the horizontal, has an entry part for the blocks which are to be sorted and a sorting part, which has at least one collecting channel running in the conveying direction. The collecting channel has a central part and two lateral run-on surfaces arranged thereon, the width of the central part corresponding at least approximately to one of the two shorter edge lengths of the blocks which are to be sorted. The run-on surfaces are provided with stop elements, the stop elements on one run-on surface being offset in the longitudinal direction with respect to the stop elements on the other run-on surface.
