The present disclosure is related to a method for manufacturing slabs of artificial agglomerated stone comprising: depositing a first layer (1.1) of a first mixture (M.sub.1) onto a surface (2), wherein the first layer having a first thickness h.sub.1, creating at least one cavity (3), having a width w.sub.i and a length L.sub.i, in the first layer (1.1) of first mixture (M.sub.1), depositing a second mixture (M.sub.2) into the at least one cavity (3) of the first layer (1.1), forming a second layer (1.2) by depositing the first and second mixtures, and the second layer having a second thickness h.sub.2, compacting and hardening the second layer (1.2), wherein the method further comprises after step c) and before step d), inserting a first tool (5) at least partially into the second thickness h.sub.2 of the second layer (1.2), and actuating the first tool (5) wherein the first tool (5) is configured to stir the first wall portion (4.1) while not stirring the second wall portion (4.2).

The present invention relates to a method for manufacturing a slab comprising solid fillers and organic binders. More in detail the present method comprises a method for manufacturing a slab having a front layer and a rear layer, said slab comprising fillers, organic binders and additives. The present method furthermore relates to a slab obtained according to the present method.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

A machine for dry decoration of ceramic slabs or tiles, comprising: a support element (10), provided with a plurality of cavities (11) with a pre-established shape; a dispensing device (20), configured to deposit a pre-fixed amount of powder material inside one or more pre-established cavities (11); an unloading device (30), configured to move the cavities (11) from a loading position, in which they can receive the powder material from the dispensing device (20), to an unloading position, in which they can unload the powder material.

A process for the realization of slabs of ceramic and/or stone material, including the following phases of: supplying at least one base material of the ceramic and/or stone type in the form of powder and/or granules and/or flakes; supplying at least one additional material of the ceramic and/or stone type in the form of powder and/or granules and/or flakes, different from the base material; delivering the base material onto a supporting surface to obtain a slab to be compacted having an initial thickness; pressing the slab to be compacted to obtain a compacted slab having a final thickness. Following the delivery and before the pressing, the following phases of: suctioning a portion of the base material to obtain at least one through groove which crosses the initial thickness along a determined path; and applying the additional material inside the groove.

A method for decorating in thickness a ceramic slab, comprising the following steps: preparing, on a decoration surface (10), a first soft decorated layer (L1) of ceramic material endowed with a decoration (V); progressively transferring, by deposition, the soft decorated layer (L1) from the decoration surface (10) to a first deposition surface (50), situated at a lower height than the decoration surface (10), thus progressively forming on the first deposition surface (50) a second soft decorated layer (L2) which has a head (H) and a tail (T); progressively transferring, by deposition, the second soft decorated layer (L2) from the first deposition surface (50) to a second deposition surface (83), situated at a lower height than the first deposition surface (50), starting from the tail (T) of the second soft decorated layer (L2), thus progressively forming on the second deposition surface (83) a third soft decorated layer (L3).

This invention is an additively manufactured wall panel using computer aided design (CAD) and computer aided manufacturing (CAM) to design and manufacture multi-colored and multi-layered wall panels. This results in a variety of highly attractive, multi-colored wall panel faces ranging from brick, colored grout lines and multi-colored stones to multi-colored geometric designs. The design and manufacturing process greatly reduces the amount of precast cementitious materials by efficiently using higher quality materials. This reduces cost and weight while simultaneously producing a much more comprehensive, multi-functional wall panel complete with an interior frame, exterior insulation and an air, vapor and moisture barriers.

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

Plant (2) for the production of slabs made of composite stone material from a mix (M) containing granules of stone or ceramic or glass material and a binder, comprising at least one temporary support or mould (S), a distributor for the mix (M) designed to distribute a layer of mix (M) on the temporary support or mould (S), a station (4) for performing compaction by means of vacuum vibro-compression of the mix (M) arranged on the temporary support or mould (S) and a station for hardening the mix (M) so as to form the finished slabs. The plant (2) comprises a device (1) positioned downstream of the distributor and upstream of the compaction station (4) and comprising means (16) which act on the top surface of the mix (M) for pre-compaction and levelling of the mix (M) arranged on the temporary support or mould (S). The invention also relates to a method for the production of slabs of composite stone material from a mix (M).
