PROCESS FOR THE PRODUCTION OF STONE MATERIAL MANUFACTURED ARTICLES
Process for the realization of manufactured articles in stone material, characterized by comprising the following steps of: providing a block or flat sheet of said stone material, and gluing a support in a flexible material on a surface of said sheet, carrying out the cutting or sectioning of said sheet to obtain a laminated panel with a determined minimum thickness, carrying out the winding of the mentioned laminated panel on a roll or similar curved surface to obtain the crushing of said panel into irregular chunks or parts; carrying out the impregnation or spreading on said crushed panel with polymeric materials or thermosetting resins; recomposing the planarity of said impregnated panel thus obtained.
The present invention relates to a process for obtaining an annular element for a wire for cutting stone material, comprising the following sequential steps: fitting at least one elastically yieldable element (5) on a bar (8); placing a portion of the bar (8) with the elastically yieldable element (5) in a mold (9); and molding, at least around the elastically yieldable element (5), an embedding matrix (6) whereby in the mold (9), an annular element (1a, 1b) is delimited having an external work surface (2) and an internal surface (3) delimiting a through opening (4); the elastically yieldable element (5) being placed at the internal surface (3) and comprising a helical spring (5) placed with position substantially coaxial with the through opening (4), such that the turns of the helical spring (5) delimit respective spirals with centers substantially aligned with a longitudinal axis (x-x) of the through opening (4); the elastically yieldable element (5) at least partially embedded in the embedding matrix (6). The process requires for waiting a certain time period for the hardening of the matrix (6); extracting, from the mold (9), the bar (8) with the at least one annular element (1a, 1b) thus obtained; and removing the one bar (8) from the at least one annular element (1a, 1b), thus obtaining a finished annular element (1a, 1b).
