Claim:
Plant for manufacturing foam products, of latex, shaped as a continuous layer to be subdivided into single pieces, said plant comprising: a laying surface for the foam moving continuously between two stations, first and second stations respectively; driving means for moving said laying surface; a device close to the first station for laying and forming a foam layer, said layer being delimited by a first face touching the laying surface, a second face opposite to the first one and two sides; a vulcanizer between the two stations; wherein the plant comprises: a plurality of plates disjoined from one another, each of them containing at least a base surface provided with moulding means devised to impress figures having predetermined outline and size in the upper part of the layer; operating means for moving said disjoined and disconnected plates from a resting position, where said moulding means are above the layer, to an operative position in a moulding station, where said moulding means impress said figures and to remove said moulding means from the operating position up to said resting position; tight means between the ends of the plates placed adjacent to each other on the continuous layer, said tight means between ends of contiguous plates for producing a hermetic seal between the contiguous plates to avoid penetration of condensation drops inside the foam; supporting means aimed to support the weight of the plates by means of thrusts directed upwardly from the laying surfaces; means for joining the plates to the laying surface of the latex foam; means for advancing forward the plates together with the laying surface of the latex foam from the moulding position to an extraction position before the second station; means for removing each single plate apart from the other ones in an extraction station upstream of the second station.
