A plant for the production of slabs from a mixture of agglomerate comprises a station (50) with a mixture distribution unit (52) which pours the mixture onto the inner surface of a slab forming mould (11) present in the station. The mould (11) is provided with a sheet (15) of plastic protective material arranged above the inner surface of the mould and which forms the surface for contact with the mixture which is introduced into the mould by the distribution unit (52). The station comprises air suction means which are coupled/connected to suction ducts (54) which are present in the mould and which emerge with their front end inside the mould in a zone of the mould situated between the inner surface of the mould and the sheet (15), so as to allow the suction of air between the sheet and this inner surface and bring the sheet (15) against this surface by means of a vacuum. A method for the production of slabs is also described.
Plant for production of slabs from a mixture of agglomerate, comprising a station with a unit for distributing the mixture and at least one mould, the distribution unit configured for pouring the mixture into an impression of the mould, the mould being provided with an elastic sheet of plastic protective material arranged above the said impression and forming the surface for contact with the mixture which is poured into the mould by the distribution unit, wherein the plant comprises air suction means which are connected to suction ducts that are present in the mould and emerge with their front end inside a zone of the mould situated between a surface of the mould impression and the sheet, so as to allow suction of the air between the sheet and said surface of the impression and bring the sheet against said surface of the impression by means of a vacuum, wherein said sheet of plastic protective material is secured to a peripheral edge of the mould surrounding said mould impression and in that the sheet of plastic protective material is secured to the peripheral edge of the mould by means of an adhesive layer, and wherein the plant comprises, in sequence, upstream of the station with the mixture distribution unit, a first station for application of the adhesive layer on the peripheral edge of the mould and a second station for deposition of the sheet of plastic protective material.
Method for production of slabs from a mixture of agglomerate, comprising the steps of providing a mould with an impression for forming the slab, laying an elastic sheet of plastic protective material over said impression so as to realize with the sheet a surface for contact with the mixture which is to be poured into the mould, securing said sheet of plastic protective material to a perimetral edge of the mould which surrounds the said mould impression, sucking the air between the sheet and a surface of the mould impression so as to bring the sheet against this surface of the impression by means of a vacuum, and pouring the mixture into the mould, wherein the sheet is arranged above said impression with the further step of applying a layer of adhesive between the sheet and a peripheral edge of the mould around said impression, and wherein the step of applying a layer of adhesive between the sheet and the peripheral edge of the mould is performed by a first station and the step of laying the elastic sheet of plastic protective material over said impression is performed by a second station.
