Abstract
Process for continuous manufacture of latex foam rest articles such as mattresses, cushions and the like comprising a part able to participate to the manufacture steps and to remain embedded in the article with consequent improvements of final performances. A flexible perforated band, preferably a flat polymeric material net with longitudinal and cross reinforcement members, is placed over a foam laying surface provided with protuberances and in continuous advancement between a foam laying station and an unlimited length article extraction station. The latex foam passes through net holes forming an upper portion and a lower portion relative to said net. The net continuously opposes contraction forces and weight force exerted from upper portion on lower portion. The unlimited length article is subjected to successive cross cuts originating rest articles wherein a foam embedded net is arranged on ends of recesses originated by the protuberances.
