Claim:
Plant for manufacturing a continuous foam layer of undefined length comprising: a plurality of laying planes; a plurality of metal tables provided with metal protuberances, said laying planes having predetermined first and second length dimensions at right angles to each other along a same planar surface, said laying planes for continuously advancing with the laying plane first length dimension oriented in an advancing direction (F) from a foam laying station to a layer removing station and then to a cutting station, with said tables having said protuberances, as upwardly cantilevered protuberances, forming a surface for depositing the foam from the foam laying station, said cutting station for cutting said continuous foam layer along the predetermined second length dimension transverse to the advancing direction (F) into a sequence of rest articles wherein the rest articles are mattresses with recesses, said foam layer being defined by two faces, at least one of which crossed by cells moulded by said protuberances, the tables provided with said protuberances overlapped to each laying plane and at least partially covering the laying plane; the tables provided with said protuberances are removably fitted on each laying plane at least along one of said predetermined first and second length dimensions to be removable from the laying plane which the respective table overlaps wherein the plurality of tables comprises spaced juxtaposed side by side placed tables forming a surface for foam deposit, wherein a first said table of said plurality of side by side tables having a protuberance distribution different from that of a second said table juxtaposed placed side by side to said first table, and wherein said tables are slidably removably fitted on the laying plane.
