A method for producing engineered stone slabs includes depositing fragments onto a surface and using a height limiting device to disrupt the fragments so a height of the fragments at the highest point from the supporting structure is substantially the same height as the height limiting device from the supporting structure. The method then includes using a digital printing device, in a first digital printing step, to print an image onto at least part of a top and side walls of at least some of the fragments, and then depositing additional composite material onto at least some of the fragments. The method further includes using a digital printing device, in an additional digital printing step, to print an image onto at least part of the additional damp composite material, and then using a press roller to press, flatten and stretch the fragments into a slab.

A plant for manufacturing ceramic articles comprising two feeding devices, each of which is configured to contain a powder material of a respective type and feed this powder material to a conveyor assembly. The plant further comprises an operating device, which is configured to allow the powder material to exit selectively from zones of the feeding devices arranged in succession crosswise to the movement direction, moving vertically and independently from one another a plurality of transfer moving parts, each provided with a transit channel through which the powder material moves to reach the conveyor assembly.

This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

The present invention relates to an electrostatic chuck heater having a bipolar structure, the electrostatic chuck heater comprising: a heater body having an internal electrode and an external electrode for selectively performing any one of an RF grounding function and an electrostatic chuck function according to a semiconductor process mode; and a heater support mounted below the heater body so as to support the heater body.

A method of producing concrete blocks for creating a surface covering, wherein each concrete block comprises a multiple-layer concrete block body with at least one level concrete block underside and, opposite the at least one level concrete black underside, an essentially flat concrete block upper side, wherein the multi-layer concrete block body comprises a first concrete block layer designed as a facing concrete layer and forming the concrete block upper surface, at least one second concrete block layer designed as a core concrete layer, as well as at least one third concrete block layer forming the concrete block underside. In the method at least one formwork is provided.

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 (O) 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 ceramic compound contained in the storage container (F) and to process a corresponding measurement signal; The control module is arranged to regulate the dispensing of ceramic compound as a function of the measurement signal received, so as to maintain a desired amount of ceramic compound inside the container (F).
