In the method for manufacturing conglomerate stone slabs using the Bretonstone technology, in the variant where the starting mixture is enclosed between two paper sheets, the improvement consists in replacing each paper sheet with a containment element consisting of a paper sheet, one surface of which has, applied thereon, a film of plastic material which is impermeable to organic vapours, impermeable to the liquids and in particular to the liquid resin constituting the binder of said mixture, resistant to the catalysis temperatures of the said resin and resistant to hot solvents and chemical vapours. Preferably, said plastic material is water-soluble, in particular polyvinyl alcohol.

Method for manufacturing conglomerate slabs

A mix dispenser () comprises a hopper () with a top opening () for filling the hopper with a predetermined amount of mix and a bottom opening (). The dispenser comprises a conveyor () which forms the bottom of said hopper () and is designed to extract the mix from the hopper () and convey it towards an end from where it falls into a mould. The dispenser is characterized in that said conveyor () comprises a supporting meshwork () made of a material resistant to the vapours of solvents such as styrene and operated by an electric motor (). Furthermore a plant comprising such as dispenser is also described.
