Plant for continuously manufacturing a foam layer to form rest articles

Plant for manufacturing a foam layer of undefined length comprising a plurality of laying planes provided with protuberances, said laying planes having predetermined width and length dimensions at right angles to each other along a same planar surface, said laying planes being continuously advanced with their width (I) oriented in the advancing direction (F) from a foam laying station to a layer removing station and then to a cutting station, said continuous layer being cut into a sequence of rest articles, said layer being defined by two faces, at least one of which crossed by cells moulded by said protuberances,

• said plant being comprises at least one table provided with said protuberances, said table being overlapped to each laying plane and at least partially covering the laying plane;
• said at least one table provided with protuberances is fitted on each laying plane at least along one of said predetermined dimensions;
• at least one other table provided with protuberances is inactively arranged beside that plant and replaceable with said at least one table provided with protuberances of the plant.
