<p>For producing stone strips a plurality of moulds (5) are filled with a concrete mixture for which the moulds (5) are continuously transported in a closed path passing a filling station (6) having supply means (7) for the concrete mixture, in which filling station (6) the moulds (5) are filled with the concrete mixture. Then, the moulds (5) pass through a setting distance (18) and arrive at a release station (20) in which the formed stone strips (2) are released fom the moulds (5) after at least partially setting of the concrete mixture. Between the release station (20) and the filing station (6) the moulds (5) are conveyed through a heating distance (22) for heating the moulds (5). The mould includes two elongated mould parts (27) guided on both sides in slots (29) by means of guiding pins (28), said slots (29) being formed in support plates (30) which can be coupled to the transport means (3) and which extend laterally of the mould parts (27), said mould parts being movable with respect to the support plates (30) between a first position, in which the mould (5) is closed and the mould parts (27) sealingly abut each other with their facing sides and enclose the stone strip form, and a second position in which the mould is opened and the formed stone strip (2) can be released from the mould (5).</p> |
