Embodiment Construction

[0025] Referring to said views, the reference number 1 indicates as a whole an apparatus for forming tiles or slabs according to the invention.

[0026] According to one embodiment of the invention, said device 1 comprises a drop-on surface, in this example a conveyor belt 2 , on which is placed a device, indicated in its entirety at 3 , for feeding a mixture of powders 33 In order to produce a continuous or discontinuous powder belt 100 on the belt 2 , the suction scraping system 4 , the continuous extrusion station 5 and the cutting station 6 .

[0027] Said means for feeding the mixture of powders 33 are in figure 1 Examples include three conduits 32 for feeding powder 33 of different properties and / or colors, a collection surface 31 for the powder and a pusher 30 .

[0028] Three conduits 32 are fed with atomized powder 33 by a feed system not shown, each conduit 32 being fed with a powder 33 of a different color than the powder of the remaining conduits. Alternatively, ...

Abstract

A device (1) for prearranging powder (33) for forming tiles or slabs, comprising: means (3) for feeding powder (33), a hopper (34) and a An underlying movable drop-off surface (2, 200, 250) for receiving powders (33) discharged from a funnel (34) shown with a front face (43a) and the prismatic shape of the rear face (34b), said front face and rear face facing each other transversely to the direction of advancement of the drop-on surface (2, 200, 250), the distance (B) between said faces (43a, 34b) being substantially equal to The thickness (S) of the powder band (100, 100') to be compacted deposited on said surface (2, 200), said powder band (100, 100') being replicated with the powder ( 33) The same arrangement for the mixture.

Description

technical field [0001] The present invention relates to a pre-layout method and apparatus for forming tiles and slabs. Background technique [0002] Research in the field of ceramics is currently aimed at obtaining products that imitate natural stones such as marble and granite. These products are characterized by the presence of a continuous random pattern of grain extending through the entire thickness of the board. [0003] Such tiles or slabs are produced by compacting semi-dry atomized ground or regranulated powders in a prearranged or arbitrary manner mixed together by hydraulic presses. [0004] Specifically, the powder mixture is deposited by suitable means in the forming cavity of the hard steel die provided in the extruder and then extruded to obtain the product. [0005] The same applicant has devised a method of brick formation which is described in Italian patent application RE2001A000129. [0006] The method consists in depositing in a hopper a mixture of po...
