Abstract:
Machinery (10) for producing artificial stones comprises a hopper (30) which is capable of containing an admixture of least cement and water and conveying it in moulds provided into a rotary formwork (40); there are provided on two opposing walls of the hopper (30) two vibrators (36) which are capable of imparting a vibration to the hopper. A process for producing artificial stones comprises the steps of mixing at least cement and water, transferring the admixture obtained to a hopper (30), imparting a vibration to the hopper by actuating two vibrators (36) which are arranged on two opposite walls of the hopper (30), pouring the admixture from an opening (34) of the hopper (30) into at least one mould form of a rotary formwork (40) in order to form at least one artificial stone, rotating the rotary formwork in order to remove, as a result of gravitational force, the at least one artificial stone.
Abstract:
A flexible mat forming system may include an elongate, rotatable drum having a plurality of transverse rows of mold cavities about an outer periphery thereof, an elongate hopper positioned adjacent the drum, the hopper shaped to receive a hardenable paste and deposit the hardenable paste along a facing row of the plurality of transverse rows of mold cavities, a spool assembly for feeding a sheet of mesh material between the hopper and the facing row, and a retaining plate extending partially about the outer periphery of the drum and positioned on a downstream side of the elongate hopper, the retaining plate spaced sufficiently close to the outer periphery to retain the mesh material against the outer periphery of the drum and the hardenable paste within the mold cavities adjacent the retaining plate.
