Abstract: A dispensing device for granular or powdered materials, comprising: a main body; a dispensing channel, arranged at least partially in the main body and provided with a longitudinal axis, an inlet opening and an outlet opening; a suction means, provided to retain, upon command, at least a part of granular or powdered material inside the dispensing channel, so as to form an accumulation that obstructs the dispensing channel and prevents the flow of material; at least one suction opening, placed in communication with the dispensing channel and with the suction means; a filter, interposed between the suction opening and the dispensing channel; a ventilation portion, associated with the main body and connected to the inlet opening, which is provided with an outer surface placed in communication with an environment at a determined pressure.

Abstract: A machine for dry decoration of ceramic slabs or tiles, comprising: —a deposit plane (50); —a distributor unit (D), arranged to dispense, in a controlled manner, a ceramic compound in granular or powdered form, formed by two or more different ceramic materials; —a storage container (F), interposed between the distributor unit (D) and the deposit plane (50) to store a certain quantity of ceramic compound dispensed by the distributor unit (D), and comprising an unloading opening (0) arranged to allow the deposit of the ceramic compound on the deposit plane (50); wherein the storage container (F) and the deposit plane (50) are in relative movement with respect to one another along a longitudinal direction (Y); —a control module, connected to the distributor unit (D) and arranged to control and regulate the dispensing of ceramic compound by the distributor unit (D); The machine comprises one or more sensors (S), connected to the control module and arranged to detect a significant parameter of the quantity of cera

Abstract: A method for realising a ceramic slab, comprising the following steps: arranging on a first deposition plane (50) a decorated layer (L2) provided with a decoration (200), gradually depositing the decorated soft layer (L2) from a head (H) to a tail (T); gradually transferring the soft layer (L2) by deposition from the first deposition plane (50) to a second deposition plane (83), placed at a lower height than the first deposition plane (50), starting from the tail (T) of the second soft layer (L2), gradually realising a second layer (L3) on the second deposition plane (83).

Abstract: Levelling device for materials in powder or granule form, comprising: a rest plane (2), mobile in advancement along a longitudinal direction (X) and predisposed to transport a layer (L) having a thickness (S) of material in powder or granule form. The device comprises a leveller (5,6), positioned above the rest plane (2).

Abstract: A dispensing device for dispensing a granular material, comprising a dispensing channel (20) provided with an inlet opening (21) and an outlet opening (22). The dispensing channel (20) comprises an intermediate portion (23), which connects the inlet (21) and outlet (22) openings and is provided with a longitudinal axis (Y); the intermediate portion (23) has a length (L) and a height (H), measured on a vertical plane containing the longitudinal axis (Y), wherein the height (H) is measured perpendicular to the length (L). The intermediate portion (23) is configured to enable the deposit and accumulation of a predetermined quantity of granular material coming from the inlet opening (21); Motor means are provided which can be activated on command to cause the granular material to flow in advancement from the intermediate portion (23) towards the outlet opening (22).

Abstract: A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.

Abstract: Dispensing device for granular or powdered materials, comprising: a dispensing channel (2a), provided with a longitudinal axis (X), an inlet opening (21) and an outlet opening (22); suction means, arranged to retain, on command, at least a portion of granular or powdered material in contact with an inner surface of the dispensing channel (2a), so as to form an accumulation which obstructs the dispensing channel (2a) and prevents the flow of material.

Abstract: Levelling device for materials in powder or granule form, comprising: a rest plane (2), mobile in advancement along a longitudinal direction (X) and predisposed to transport a layer (L) having a thickness (S) of material in powder or granule form. The device comprises a leveller (5,6), positioned above the rest plane (2).

Abstract: A pressing method for pressing ceramic slabs, comprising the following steps: spreading a layer (1) of granular or powdered material onto a pressing plane (2), wherein the layer (1) comprises at least a first zone (11), with a prefixed area and border, made of a granular or powdered primary material, and at least a second zone (12), with a prefixed area and border, made of a granular or powdered secondary material different from the primary material; pressing the layer (1) using a press (P); separating at least a main portion (10) of the first zone (11) from the second zone (12).
