A method for producing paving blocks (K) having ornamented (m) surface, comprising the steps of:
- filling a base material into a mold cavity (4a) of a forming mold (4),
- making a mixture (MK) of ornamenting material of at least a granular material and a binder, the mixture (MK) having an average grain size corresponding to the average grain size of the planned ornament (m) to be formed on the tread surface of the paver (K), and having a tint different from that of the base material, and
- applying the mixture (MK) of ornamenting material into the surface of the base material filled into the mold cavity (4a),
- determining experimentally an adequate screen aperture (X1) of holes (9a) to be created on a metering plate (9,91,92,93),
- creating holes (9a) having the experimentally determined screen aperture (X1) on the metering plate (9,91,92,93),
- applying the mixture (MK) of ornamenting material on the metering plate (9,91,92,93) provided by holes (9a) having the experimentally determined screen aperture (X1), then
- displacing the metering plate (9,91,92,93) parallel to the surface of the base material filled in the mold cavity (4a), while
- moving a metering member (10,101,102,103) on the metering plate (9,91,92,93), and thereby
- making the mixture (MK) of ornamenting material passed through the holes (9a) of the metering plate (9,91,92,93).
The method according to 7, characterized in that applying concrete mortar as the base material and colored concrete mortar as the mixture (MK) of ornamenting material.
