  • Patent number: 11904499
    Abstract: A device for producing concrete blocks, in particular concrete paving slabs, having a mold for filling with a concrete mixture, wherein the mold has at least one mold cavity for receiving the concrete mixture, and wherein the upwardly open mold cavity has walls as lateral boundaries, and wherein the at least one mold cavity can be filled with the concrete mixture by means of a filling device, and wherein the mold with the at least one mold cavity and the filling device are movable relative to one another in a filling axis. The filling axis is oriented obliquely to an axis of symmetry of the at least one mold cavity, with the result that preferably all of the walls of the mold cavity extend neither perpendicularly nor parallel to the filling axis, but at an angle.

  • Patent number: 7048250
    Abstract: A method for producing purpose-made blocks (10). According to said method, several purpose-made blocks (10) are produced in a mold (37) in such a way that the blocks (10) are arranged in at least one row (28) of purpose-made blocks in the mold (37) and respective adjacent blocks (10) of a block row (28) are interconnected in a zone of at least one predetermined breaking point (30). The purpose-made blocks (10) of a block row (28) are removed together from the mold (37) and the blocks (10) are separated from one another in the zone of the predetermined breaking point (30). According to the invention, adjacent purpose-made blocks (10) of one or each block row (28) are produced in the mold (37) in such a way that axes of the purpose-made blocks (10) deviate at least partially in the longitudinal direction (32) of each block row (28) from the longitudinal axis (32) of each block row (28) and that lateral pressure is exerted on the or each molded block row (28) to separate the predetermined breaking points (30).
