  • Patent number: 7517483
    Abstract: A procedure for the production of sheets or tiles (10) in agglomerate material consisting of products comprising marble and/or granite and/or sand and/or quartz powders and binding resins, also comprising possible inclusions of elements made from metal, glass, ceramic, wood, precious stones, comprising the following processing stages: a) crushing of the components of the sheets or tiles (10); b) mixing of these components with the aforesaid binding resins; c) pressing and compacting of these components inside a pressing die, and hardening at a predetermined pressure and temperature, in order to obtain a predetermined shape, advantageously quadrangular, and predetermined dimensions of these sheets or tiles (10); and according to which before stage c) is carried out a metal plate (11) is positioned inside the pressing die and presents an irregular structure designed to accommodate the mixture of the components which, during the polymerisation and hardening stages, bond to the plate (11) thus forming the base of

  • Publication number: 20050230868
    Abstract: A method for obtaining antique-look slabs (10) made of stone agglomerate material has a first step of crushing the various materials of which the agglomerate consists, a second step of mixing the crushed materials, to obtain as homogeneous a product as possible, during which the binding resins are added, a third step of preparing a shaped die on the base of which there is a firset layer of paper, advantageously polyethylene-coated paper, a fourth step of pouring the crushed materials into the die, a fifth step of covering the pressed agglomerate material with a second layer of paper, advantageously polyethylene-coated paper, a sixth step of pressing and compacting the agglomerate, during which the desired shape is obtained, a seventh step of hardening the sheet or panel (10) at a predetermined temperature, an eighth step of separating the second layer of paper from the sheet (10), in which the second layer of paper is separated from the sheet (10) by simply lifting and removing the paper substantially in a si

  • Patent number: 6846552
    Abstract: A plant (10) for the production of highly flexible and relatively thin sheets or panels (38) of agglomerate material comprising: a mixer crusher (12), a hopper (15) designed to accept the crushed and rolled material (24) and to transfer it to a distributor or spreader (16) positioned below the hopper, said spreader (16) comprising a substantially cylindrical container (30) with a loading opening (31), adjacent, in use, to said hopper (15) and comprising a discharge slot (32) on the opposite side to said opening (31), and a mixing device of the agglomerate material (24) inside said container (30). The mixing device comprises a pair of blades (35) fixed to a shaft (34) rotating around an axis not corresponding to that of said container (30) and in particular offset towards said slot (32), so that during their rotation the blades almost skim said slot.
