Abstract (en)
[origin: EP1676684A2] Production of building stone especially hollow block stone consisting of inner and outer parts which via legs (3) stretching over only part of the stone height, are connected together in a mold where the stone material is compressed from starting height H1 by means of a press die to final height H2. The compression cross-section in the mold (1) in the compression region over the leg (3) is such that in the leg region a higher degree of compression is attained than in the remaining region of the stone. An independent claim is included for a building stone stone as described above.
