Abstract

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).

First claim

What is claimed is:

1. A process of forming a processed slab from different particulate mineral mixes, comprising:
positioning a slab mold in a substantially non-horizontal orientation, the slab mold defining a mold space that is at least 6 feet long by at least 2 feet wide;
dispensing a first combination of differently pigmented particulate materials into the substantially non-horizontally oriented mold to define a first layer defined by the first combination of differently pigmented particulate materials;
dispensing additional pigmented particulate material to define a plurality of successive layers of differently pigmented particulate material;
adjusting the mold to a substantially horizontal orientation while the multiple pigmented particulate materials are in the mold; and
vibrating and compacting the multiple pigmented particulate materials arranged in the mold while the mold is in the substantially horizontal orientation.

2. The process of claim 1 , wherein dispensing additional pigmented particulate material comprises pouring multiple differently pigmented particulate quartz mixes into the substantially non-horizontally oriented mold according to a predetermined pattern.

3. The process of claim 2 , wherein the mold space has a first edge thickness that is smaller than and parallel to a second edge thickness proximate to an upwardly facing opening of the mold.

4. The process of claim 1 , wherein dispensing a first combination of differently pigmented particulate materials comprises dispensing each differently pigmented particulate material from separate conveyor lines.

5. The process of claim 4 , wherein the respective differently pigmented particulate materials are transported to a region above the upwardly facing opening of the mold by the respective separate conveyor lines.

6. The process of claim 5 , wherein dispensing additional pigmented particulate material comprises dispensing additional pigmented particulate material from one or more additional conveyor lines that are different than the separate conveyor lines that dispense the first combination of differently pigmented particulate materials.

7. The process of claim 1 , wherein dispensing the first combination of differently pigmented particulate materials into the substantially non-horizontally oriented mold comprises dispensing differently pigmented particulate materials from multiple material distributors.

8. The process of claim 1 , wherein dispensing additional pigmented particulate material comprises dispensing differently pigmented particulate materials from multiple material distributors.

9. The process of claim 1 , wherein the mold is positioned to receive pigmented particulate materials from four material distributors when in the non-horizontal orientation.

10. The process of claim 9 , comprising selectively operating the material distributors to dispense the pigmented particulate materials from one or more of the four material distributors into the mold while the mold is in the non-horizontal orientation.

11. The process of claim 1 , wherein the vibrating and compacting is contemporaneous and provide a rectangular processed slab having a thickness that is generally constant at its four edges.

12. The process of claim 1 , wherein at least some of the successive layers of pigmented particulate material provide lengthwise veins of the processed slab.

13. The process of claim 11 , wherein the successive layers of pigmented particulate material provide at least a first vein extending generally lengthwise from edge-to-edge.

14. The process of claim 12 , wherein a first lengthwise vein is defined by a first particulate quartz mix, a second lengthwise vein is defined by a second particulate quartz mix, and a third lengthwise vein is defined by a third particulate quartz mix.

15. The process of claim 12 , wherein a first lengthwise vein is defined by a first particulate quartz mix, and a second lengthwise vein and a third lengthwise vein are defined by a second particulate quartz mix.

16. The process of claim 1 , comprising, while the mold is in a substantially horizontal orientation, dispensing a pigmented particulate material to provide a transverse pigmented vein that does not extend through an entire thickness of the mold.

17. A process of forming a processed slab from different particulate mineral mixes, comprising:
positioning a slab mold in a substantially non-horizontal orientation, the slab mold defining a mold space that is at least 6 feet long by at least 2 feet wide, the mold space having a first edge thickness that is smaller than and parallel to a second edge thickness proximate to an upwardly facing opening of the mold;
dispensing a first combination of differently pigmented particulate materials into the substantially non-horizontally oriented mold, while a mold end cap associated with the upwardly facing opening is in an open position, to define a first layer defined by the first combination of differently pigmented particulate materials;
dispensing additional pigmented particulate material into the substantially non-horizontally oriented mold, while the mold end cap is in the open position, to define a plurality of successive layers of differently pigmented particulate material;
adjusting the mold to a substantially horizontal orientation while the multiple pigmented particulate materials are in the mold; and
vibrating and compacting the multiple pigmented particulate materials arranged in the mold while the mold is in the substantially horizontal orientation and the mold end cap is in a closed position.

18. The process of claim 17 , wherein the dispensing additional pigmented particulate material comprises pouring multiple differently pigmented particulate quartz mixes into the substantially non-horizontally oriented mold according to a predetermined pattern.

19. The process of claim 18 , wherein dispensing the first combination of differently pigmented particulate materials comprises dispensing each differently pigmented particulate material from separate conveyor lines.

20. The process of claim 19 , wherein the mold is positioned to receive pigmented particulate materials from four material distributors when in the non-horizontal orientation.
