AMENDED CLAIMS

received by the International Bureau on 17 April 2019 (17.04.2019)

1. Apparatus for producing a paver block (K) having veined tread surface, the ap paratus comprising: a starting table (51); a filling carriage (5) being movable back and forth in a first direction (Fl) along a guide rail (3) above a molding template (6) con nected to the starting table (51) and having at least one mold cavity (6a); and a cham ber (5 a) being open both at its upper and lower sides for receiving a base material is provided in the interior space of the carriage (5); metering trough (1, 2, 3) connected to a dispensing device (41); and the apparatus is provided with a further, second start ing table (8), and a second filling carriage (7) arranged movably along a guide rail (32) over the molding template (6) in the second direction (F2) above the starting table (8), and the apparatus is provided with at least two metering trough (1, 2, 3); and a batch box (4) to be loaded by the dispensing device (41), characterized in that the batch box (4) provided with an open top and an emptying device (42) at its lower side is arranged movably over the starting table (51) on a plane parallel to the plane of the starting ta ble (51); and the second starting table (8) being movable in a second direction (F2) along a guide rail (31) above the molding template (6), the second filling carriage (7) is provided with chambers (7a) open both upper and lower sides ; and a second batch box (9) with open top and lower sides is provided above the second filling carriage (7).

2. Apparatus according to claim 1, characterized in that the second batch box (9) is in a fixed position relative to the guide rail (32).

3. Apparatus according to claim 1, characterized in that the second batch box (9) is movable in the second direction (F2) along the guide rail (32).

4. Apparatus according to claim 1 to 2, characterized in that the first di rection (Fl) and the second direction (F2) include an angle (a) of n * p/2, where n is a natural number.

5. Apparatus according to claims 1 to 4, characterized in that the second carriage (7) is formed as a plate and the chambers open both at bottom and top sides are holes (7 a). 12

6. Apparatus according to Claims 1 to 4, characterized in that chambers (7a) open both at top and bottom of the second filling carriage (7) are formed as a slot system.

7. Apparatus according to Claims 1 to 6, characterized in that the dis pensing device (41) is a screw dispenser.

8. Apparatus according to claims 1 to 7, characterized in that the base material is selected from the group consisting of concrete mortars colored in its mate rial and uncoloured concrete mortar.

9. A method for producing a paver block (K) having veined tread surface by means of the apparatus according to any of claims 1 to 7, wherein first metering trough (1) of the apparatus being filled with a base material colored by a first dyestuff and a second metering trough (2) being filled with a base material colored by a second dyestuff, and the base material being fed from the trough (1,2) into the mold cavity (6a) of the moulding pattern (6), then compacted and allowed to be set, by dividing an inner space of a filling carriage (5) placed on a starting table (51) into target areas (Cl, C2, C3, C4, C5, C6), and during feeding the base material in the mold cavity (6a), a) a part of the base material is fed into a batch box (4) from the trough (1), batch box (4) is moved over the selected target area (Cl) of the interior space of the filling carriage (5), dispensing device (41) of the batch box (4) is activated to feed the base material from the batch box (4) to the target area (Cl), then

b) repeating step a) by filling all other target areas (C2, C3, C4, C5, C6), and c) moving the filling carriage (5) from the starting table (51) in the first direc tion (Fl) over the molding template (6) and retracting it, characterized by

filling up with base material a batch box (9) with bottom and top openings ar ranged above the second filling carriage (7) located on the second starting table (8), and filling the open chambers (7a) of the second carriage (7) from the second batch box (9), and then moving the second filling carriage (7) together with the second start ing table (8) in a second direction (F2) over the molding template (6), and retracting the second starting table (8) in the second direction (F2), thereby feeding the base ma terial arranged in the open chambers (7a) into the surface of the base material fed in the molding template (6) during the step c). 13

10. A method according to claim 9, characterized by filling up the open chambers (7a) of the second filling carriage (7) from the second batch box (9) by mov ing the second batch box (9) in the second direction (F2).

11. A method according to claims 9 to 10, characterized by the second fill- ing carriage (7) is formed as a sheet and the open chambers (7a) of the second filling carriage (7) are formed as holes.

12. A method according to claim 11, characterized by the chambers (7a) open at the top and bottom of the second filling carriage (7) are formed as a system of slits.

13. A method according to claim 12, characterized by selecting the base material from the group consisting of concrete mortars colored in its material and un coloured concrete mortar.
