Abstract: A printing device for building material articles, comprises a tank (2) for a printing material, solid or liquid, to be dispensed, an outlet mouth (3) suitable for dispensing the printing material onto a work surface, a conduit (5) extending along its own main direction (A) between the tank (2) and the outlet mouth (3), in which the conduit (5) comprises at least one deformable wall (6) movable between an operating position, in which it determines the creation of a restriction in the conduit (5) preventing the flow of the printing material towards the outlet mouth (3), and a rest position, in which it allows the flow of the printing material towards the outlet mouth (3).

Abstract: An apparatus for supplying material to a plant for producing slabs. The apparatus comprises means for supplying the material to be formed, first collecting and moving means, a conveyor cassette and second collecting and moving means. The means for supplying the material take the material from reservoirs and deposit it on the first collecting and moving means to form a semi-finished mat. The first collecting and moving means provide a stable base for the material and move the semi-finished mat towards the conveyor cassette, which receives the semi-finished mat and deposits a uniform pad on the second collecting and moving means. The second collecting and moving means provide a stable base for the uniform pad and move it towards successive stations in the plant. The conveyor cassette comprises at least one flap adapted to cross the entire thickness of the flow of material which, goes through the conveyor cassette.

The second means provide a stable base for the uniform pad and move it towards successive stations in the plant. The walls of the conveyor cassette, in use, at least partly support the materials weight and comprise active surfaces The conveyor cassette has, an angled shape, comprising a first rectilinear portion and a curved one.

Abstract: An apparatus for forming desired patterns on ceramic tile from a slurry comprising: a means for preparing a slurry; at least one slurry holding tank for holding at least one type of slurry; at least one pattern forming tray; at least one means for connecting said at least one tank to at least one pattern forming tray and a filter pressing unit; wherein the pattern forming unit dispenses a predetermined type, amount, colors of slurry at a predetermined order into the pattern forming tray to form a desired pattern, said slurry with desired pattern is pressed with the filter pressing unit to form ceramic tiles or slabs with a desired pattern running though its entire thickness.
