Abstract
A distributor device (1) for distributing a mix (L) in one or more forming supports (S) for manufacturing articles made of composite stone material. The device (1) comprises mix supply means (10) designed to transport the mix (L) along a longitudinal feeding direction (X) towards the forming supports (S). The distribution device (1) further comprises mix lamination means (16) located between the supply means (10) and the supports (S). The invention also relates to a method and a plant for manufacturing articles made of composite stone material which use the aforementioned distributor device (1).
Claims23
A device for distributing a mix onto one or more forming supports for manufacturing slabs made of composite stone material, the device and the forming supports being movable relative to each other, said distributor device comprising:
- means for supplying a layer of the mix in a longitudinal feeding direction;
- and
- means for laminating the mix, positioned between said supply means and the forming supports and comprising a first lamination roll and a second lamination roll rotatable about respective axes of rotation transverse to the longitudinal feeding direction, the first lamination roll and the second lamination roll being the lamination rolls, rotation being imparted to each of the lamination rolls by means of a respective drive, the forming supports each being formed by a sheet of paper or similar material or by a tray made of elastomer material or similar material and having a form and dimensions corresponding to those of the slabs to be made;
- wherein the device comprises a second transportation and support means or a conveyor element or a conveyor belt positioned downstream of said lamination rolls for transporting and guiding the laminated mix from said lamination rolls toward the forming supports;
- wherein said lamination rolls are spaced apart by an interspace with predetermined dimensions which can be adjusted in order to perform lamination of the mix, the second lamination roll being provided with a motorized adjustment means able to move the second lamination roll so as to adjust the dimensions of the interspace;
- wherein said motorized adjustment means comprise at least one further drive independent from the respective drive for rotation of each of the lamination rolls and connected to at least the second lamination roll of the lamination rolls;
- and
- wherein said motorized adjustment means comprise a pair of gear motors located at opposite ends of at least the second lamination roll of the lamination rolls.

A method for manufacturing slabs made of composite stone material from a mix, comprising the following steps:
- preparing a quantity of mix;
- distributing a layer of the mix on one or more forming supports, the supports each formed by a sheet of paper or similar material or by a tray made of elastomer material or similar material and having a form and dimensions corresponding to those of the slabs to be made;
- compacting the mix distributed in the forming supports;
- hardening the mix distributed in the forming supports;
- and
- upstream of the mix distribution step, a mix lamination step via means for laminating the mix comprising a first lamination roll and a second lamination roll rotatable about respective axes of rotation, the first lamination roll and the second lamination roll being the lamination rolls, the rotation being imparted to each of the lamination rolls by means of a respective drive;
- and
- wherein the method comprises upstream and/or downstream of the lamination step, at least one step for transporting the mix by means of first and/or second transportation means or by means of a conveyor belt;
- and
- wherein said lamination rolls are spaced apart by an interspace with predetermined dimensions, whereby dimensions of the interspace to perform lamination of the mix are adjusted via a motorized adjustment means of the second lamination roll for moving the second roll;
- wherein said motorized adjustment means comprise at least one further drive independent from the respective drive for rotation of each of the lamination rolls and connected to at least the second lamination roll of the lamination rolls;
- and
- wherein said motorized adjustment means comprise a pair of gear motors located at opposite ends of at least the second lamination roll of the lamination rolls.
