ABSTRACT:
The invention relates to the production of concrete roof tiles in an extrusion process, in which a continuous layer of fresh concrete is deposited on pallets supplied in a continuous row to a depositing apparatus and is subsequently compacted by means of a shaping roller and slipper and, if appropriate, profiled, and then the compacted layer of fresh concrete is cut at a cutting station into roof-tile moldings of equal length with a rear edge and a front edge, and the front edge is trimmed. To increase the weathering resistance and the strength of the front edge of the concrete roof tiles produced in this way, and to reduce the efflorescence which occurs in this region, a rounding or bevel starting from the lower cut edge adjacent to the pallet and extending up to the top side of the roof-tile moldings is produced, preferably in steps, on the front edge as a result of a compacting of material. The apparatus provided for this purpose has, as a trimming tool, an indentation tool which matches the profile of the layer of fresh concrete and which, during its movement penetrating into the layer of fresh concrete, compacts the front edge portion produced in the preceding work cycle over the entire cross-section of the latter.
