Abstract
Method for forming ceramic tiles or slabs by means of a press provided with at least one cavity, consisting of arranging a hopper above a conveyor belt supported by a movable carriage; depositing in the hopper in a prearranged and/or random manner a mixture of powders of different characteristics such as to create within the hopper a powder mass presenting the veining peculiar to a single block of natural stone; from said powder mass, withdrawing in succession portions having, in the belt advancement direction, a dimension equal to a fraction of the dimension of said hopper in the same direction, and having in the direction perpendicular to the preceding the same dimension as the hopper mouth, such as to withdraw a layer of said mass; depositing said layer onto said belt; by means of said belt, depositing the powder layer into the forming cavity of the press without mixing the powders in the belt translation direction; pressing the powers.
Claims
1. A method for forming ceramic tiles or slabs by a press provided with at least one cavity, comprising the following operative steps: a) arranging a hopper above a conveyor belt supported by a movable carriage, b) depositing into the hopper in a prearranged and/or random manner a mixture of powders of different characteristics such as to create within the hopper a powder mass presenting the veining peculiar to a single block of natural stone, c) from said powder mass, withdrawing in succession portions having in the belt advancement direction a dimension equal to a fraction of the dimension of said hopper in the same direction, and having in the direction perpendicular to the preceding the same dimension as the hopper mouth, such as to withdraw a layer of said mass, d) depositing said portions onto said belt, mutually adjacent to form a continuous strip of powders; e) remove the upper thin layer of powders in order to highlight the veining present in said strip; f) by means of said belt, depositing the powder layer into the forming cavity of the press without mixing the powders in the belt translation direction, g) pressing the powers.
2. A method as claimed in claim 1 , characterised by repeating the operative steps c) and d) to create on said belt a continuous powder strip consisting of a succession of mutually adjacent portions.
GEANDERTES BLATT (ARTIKEL 19) 15
3. A method as claimed in claim 1 , characterised in that the dimension of said powder portions in the belt translation direction is a function of the graphic resolution to be obtained on the finished product.
4. A method as claimed in claim 1 , characterised in that the dimension of said powder portions in the belt translation direction is at most four times the depth of the forming cavity.
5. A method as claimed in claim 1 , characterised in that the dimension of said powder portions in the belt translation direction is preferably between 0.5 and two times the depth of the forming cavity.
6. A method as claimed in claim 1 , characterised in that said portions are deposited into the cavity in an ordered manner by orderly depositing said portions onto said belt, and translating said belt between a loading position in which it lies spaced from said cavity and a discharge position in which, while translating above said cavity towards the discharge position, it deposits a portion of said powders into the forming cavity.
7. A plant for forming ceramic tiles or slabs by a press provided with moulds having at least one cavity, comprising, for containing a powder mixture, a hopper the discharge mouth of which has in plan view a width at least equal to the width of said at least one cavity, powder distribution means being associated with the lower mouth of said hopper, characterised in that said powder distribution means are suitable for withdrawing in succession portions of powders having in one direction a dimension equal to a fraction of the dimension of said hopper mouth in the same direction, and having in the direction perpendicular to the preceding the same dimension as the hopper mouth, such as to deposit said portions mutually adjacent to form a continuous strip of powders onto an

underlying conveyor belt which is arranged to translate between a loading position, in which it lies distant from said cavity, and a position for discharging powder portions of said strip in succession, in which it lies above said at least one cavity and while translating towards the loading position deposits said powders into the cavity until this latter is completely filled.
8. A plant as claimed in claim 7, characterised in that said belt is supported by a movable carriage which enables it to translate between the two said loading and discharge positions.
9. A plant as claimed in claim 7, characterised in that said movable carriage also supports said distribution means.
10. A plant as claimed in claim 7, characterised in that said hopper can translate relative to said distribution means.
11. A plant as claimed in claim 7, characterised in that said powder distribution means comprise a plate provided with a slot perpendicular to the belt translation direction, said plate having a dimension in the belt translation direction equal to at least double the dimension of the lower mouth of said hopper in the same direction, and a dimension in the direction perpendicular to the preceding which is at least equal to the dimension of the lower mouth of the hopper in the same direction, said slot having a dimension in the belt translation direction which is a function of the thickness of the tile to be formed, and a dimension in the direction perpendicular thereto which is at least equal to the dimension of the mould cavity in the same direction.
GEANDERTES BLATT (ARTIKEL 19) 17
12. A plant as claimed in claim 11 , characterised in that the dimension of said slot in the belt translation direction is at most four times the cavity depth.
13. A plant as claimed in claim 11 , characterised in that the dimension of said slot in the belt translation direction is preferably between 0.5 and two times the depth of the press cavity.
14. A plant as claimed in claim 7, characterised by comprising at least one scraper device downstream of said hopper.
15. A plant as claimed in claim 14, characterised in that said at least one scraper device is associated with said belt and is positioned downstream thereof.
