- the term "drop” refers to a movement of the ceramic powders 7 and 8, substantially perpendicular to the conveying plane CP (in other words, vertical) .

- the suction devices 16 and the respective delivering devices 20 are separate, in particular, the delivering devices 20 are downstream (with respect to the conveying direction D) of the suction devices 16.
- the apparatus 1 comprises a recirculation system 32 configured to bring back to the supplying assembly 12 the powder 7 which, in use, the removal device 16 sucks up from the base layer 13. In this way it is possible to reduce the consumption (and costs) of ceramic powder 7 and improve the environmental sustainability of the apparatus 1.
- the apparatus 1 also comprises a delivering assembly 35 which is controlled by a control device CD to feed an additional quantity of ceramic powder 7 (or 8) to the conveyor assembly 10 in order to vary (over time) the quantity of ceramic powder 7 (or 8) supplied by the feeding assembly 21 to the conveyor assembly 10 according to what is detected by a detection device 36.

- Each delivering device consists of a distribution element 38 (more precisely, a thin plate) placed (slightly spaced apart) below a respective lower opening so that ceramic powder 7 (or 8) can accumulate on the distribution element; and a vibrating device (not shown) designed to selectively vibrate the distribution element 38 so that the ceramic powder 7 (or 8) accumulated on the distribution element 38 slides and falls downwards.
- the control device CD is configured to selectively activate each vibrator device independently of the other vibrator devices.
- a method is provided for the production of ceramic products 2, in particular for the production of ceramic products 2 with internal streaks or veins 19.
- the method is implemented by the apparatus 1 described above.
- the method comprises a compacting step, during which, in the area of a work station 33, the powder material 5 (more precisely, the layer 23) comprising the ceramic powders 7 and 8 is compacted so as to obtain the layer 6 of compacted powder material.
- the conveyor assembly 10 conveys the base layer 13 towards (in particular, to) the feeding assembly 21. More precisely, the conveyor assembly 10 moves the base layer 13 in the conveying direction D (in particular, substantially horizontal) .
- the conveyor assembly 10 defines the conveying plane CP (in particular, substantially horizontal) . More precisely (during the supplying step) , the base layer 13 is placed and moves on the conveying plane CP.
- the base layer 13 is moved substantially continuously, in particular at an almost constant speed (excluding, of course, the start up and shutdown steps of the apparatus 1) .
- the method also comprises a removal step, during which the removal device 16 removes (in particular, by suction) at least part of the ceramic powder 7 so as to obtain at least the groove 17 in the base layer 13.
- the removal device 16 is moved (at least) in the direction T to remove, in particular by suction, (at least) part of the ceramic powder 7 and thus determining the groove 17 in the base layer 13.
- the method also comprises: a deposition step, during which the delivering device 16 (which, in particular, moves along the groove 17) deposits, inside the groove 17, the ceramic powder 8, which is different (in particular, a different colour) from the ceramic powder 7, so as to obtain a combined layer; and a feeding step, during which the combined layer (i.e. the ceramic powders 7 and 8 respectively deposited by the supplying assembly 12 and the delivering device 20) is fed (in particular by dropping) by the feeding assembly 21 to the conveyor assembly 25 forming the layer 23 (in particular, continuous) of the powder material 5 (on the assembly 25, in particular on the belt 13) .
- the combined layer i.e. the ceramic powders 7 and 8) is fed by means of the feeding assembly 21 crosswise in the direction D downwards (in particular, vertically) to the conveyor assemb1y 25.

- the removal step and the deposition step are (at least partially) simultaneous (or immediately successive - less than five seconds apart) .
- the delivering device 20 deposits the ceramic powder 8 used to create the vein 19.
- this reduces the risk that part of the groove 17 collapses before the ceramic powder 8 is deposited.
- the removal device 16 and the delivering device 20 follow the same motion law (at least) along the direction T.
- the removal device 16 and the delivering device 20 follow the same motion law in all directions in which they can move. More precisely, the delivering device 20 follows the same motion law as the removal device 16 with a predetermined delay.
- the removal device 16 and the delivering device 20 are moved by the same actuator system 34. More specifically, the removal device 16 and the delivering device 30 are integral with each other.
- the conveyor belt 11 is moved (by a control unit not shown) at a speed VI and the conveyor belt 22 is moved at a different speed V2. More precisely, the ratio between the first speed VI and the second speed V2 is substantially constant. In particular, the first speed VI and the second speed V2 are equal to each other .
- the conveyor belt 11 and/or the second conveyor belt 22 move at a constant speed.
- the position of the decorative element E is coordinated with the position of the ceramic powder 6. More precisely, the position of the decorative element E at least partially overlaps the position of the ceramic powder 8 (i.e. the vein 19 generated by it after the drop) .
- the image 30 is the image of a wooden board (also with its veins 19) .
- the position of the ceramic powder 8 is a position detected, in particular by a visual system.
- the first ceramic powder 7 is an atomized powder and the second ceramic powder 8 is a micronized powder.
- the smaller grain size of the powder 8 allows a vein 19 with a higher definition to be made than a vein 19 made using atomised powder.
- the typical grain size of micronized powders much finer than atomized (the grain size of which is usually in the range of 200 - 500 mpi) , ranges between 40 - 180 mpi .
- the particle sizes are measured as an average diameter D(v.0.5) using a laser granulometer - in particular, using a Mastersizer Microplus Ver.2.19 (Malvern Instruments ® Ltd) laser granulometer. More precisely, the particle sizes are measured according to what is required by the ISO 13320:2009 standard.
- the delivering device 16 delivers into the groove 17, a plurality of different ceramic powders 8 (e.g. of different colours and/or dimensions) .
- the plurality of ceramic powders 8 is delivered in such a way as to determine at least one colour shading. In this way, the visual effect of the vein 19 is more attractive as it is more similar to natural stone.
- the powders 7 and 8 on the conveyor belt 11 are dropped inside the hopper 24, which deposits on the conveyor belt 22 the layer 23 (continuous) of material 5 composed of the base layer 13 and the vein 19. This layer 23 is then pressed by the pressing belt 9, generating the layer 6 of compacted powder material 5. Continuing its path, the surface of the layer 6 is printed by the digital printing device 29 so as to reproduce the image 30 having at least a graphic effect E on the vein 19. Subsequently, the printed layer 6 of compacted powder material 5 passes through the firing assembly 26, in particular making the ceramic product 2.
- the apparatus 1 described above is configured to implement the method described above.
- the present invention makes it possible to create a digital image synchronized with the vein (which will be visible from the edge of the product) despite the randomness of its arrangement due to the drop.
